Assessment of whole-body vibration and development of mitigation intervention for single-axle tractor–trailer combination

IntroductionTractarization is synonymous with farm mechanization in India. Tractor-trailers are extensively used for the transportation of farm inputs and produce on and off-road, exposing drivers to excessive vibration.ObjectivesThe study was undertaken to assess tractor drivers’ vibration exposure while using trailers and to develop low-cost mitigation interventions.MethodologyThe whole-body vibrations were measured at the tractor seat during the transportation with a no, half (3715 kg soil) and full payload (5910 kg soil) trailer on two terrain conditions, namely, asphalt and farm terrains. The speeds recommended by ISO 5008-1979 of 10, 12 and 14 km/h on asphalt roads and 4, 5 and 7 km/h on farm roads, as well as actual working speeds preferred by the operator (18, 20 and 22 km/h on asphalt road and 8, 10 and 12 km/h on farm terrain), were selected for experiments. Two vibration reduction interventions, namely spring suspended single point hitch (I1) and polyurethane (PU) bush (I2), were developed and installed between the tractor and trailer. Whole-body vibration (WBV) was measured by repeating the experiments.ResultsThe maximum vibration reduction on asphalt road at 22 km/h with I1 was found as 14.3, 19.03 and 23.1%, whereas on-farm terrain at 12 km/h was found as 15.16, 22.43, and 25.56% for no, half and full payload. Similarly, with I1 + I2 interventions, the maximum total vibration reduction at 22 km/h was 16.86, 21.12 and 25.51% on asphalt roads, whereas on-farm tertian at 12 km/h was 17.07, 23.77 and 28.67%. The average value of lower health guidance caution zone (HGCZ) limits on asphalt roads increased by 1.11, 0.95 and 0.92 h and on-farm tertian 1.55, 1.14 and 0.83 h with no, half, and full payload. The average value of upper HGCZ limits on asphalt roads increased by 3.13, 3.21 and 3.68 h and on-farm tertian by 2.24, 2.94 and 3.31 h with intervention.ConclusionsThis infers that with developed interventions an operator can safely perform for a longer duration and at higher operational speeds because of the reduced vibration.

SUBSTANTIATION OF CHANGES IN THE CERTIFICATION OF THE TRACTOR DRIVER’S WORKPLACE IN MODERN MACHINE-TRACTOR UNITS

The study aims to identify possible changes in the working conditions of tractor drivers under the computerisation of workplaces and to develop proposals for changing the requirements for sanitary standards in the design of tractors and agricultural machinery. The article analyses the impact of modern technologies on the working conditions of tractor drivers in agriculture. It investigates various aspects of work, including using on-board computers, air conditioning, and satellite navigation, and their impact on workers’ health. The authors consider health risks, such as increased noise levels and work with on-board computers, and reveal the lack of consideration of these aspects in regulatory documents. In particular, we have found that using on-board computers significantly simplifies the process of controlling agricultural machinery but can lead to increased noise and vibration levels, negatively affecting workers’ health. Some studies have shown that prolonged work with on-board computers can lead to the development of occupational diseases, such as musculoskeletal disorders, impaired vision, and others. In addition, air conditioning in tractor cabs can cause colds due to sudden temperature changes and increase the risk of legionella infection due to the water condensation accumulation in ventilation systems. The research also found that the legal and regulatory documents governing the working conditions of tractor drivers do not consider the use of modern technologies, which creates gaps in worker protection. Regulatory documents should contain requirements for the parameters of monitors and their placement in the working area of tractor drivers in agricultural production, such as adjusting the reflectivity of the screen, the main adjusted visual characteristics of monitors, and the location of video terminals in the tractor cab without being directly in the line of sight. It is necessary to develop measures to prevent the overwork of tractor drivers. Regulations should include rules for the use of air conditioners, as well as for cleaning air conditioning ducts and replacing filters on time. The general conclusion is that there is a need to strengthen the regulation of tractor drivers’ working conditions and to include requirements for using modern technologies in the relevant regulations. These measures will ensure the safety and health of workers in agriculture and reduce the risk of occupational diseases. Keywords: machine-tractor unit, tractor driver, workplace certification, labour protection, video terminal.

DEVELOPMENT OF THE DERMAL EFFECT OF PESTICIDES ON PROFESSIONAL CONTINGENTS USING INNOVATIVE 3RIVE 3D TECHNOLOGY

The skin is the most vulnerable organ when spraying pesticides on fields. Farmers are also exposed to pesticides during mixing, loading of pesticides, and when cleaning equipment and disposing of empty containers. The aim. To study and analyze the features of the risk of pesticides dermal exposure to professional contingents during treatments using the innovative 3RIVE 3D pesticide application technology. Materials and methods. The 3RIVE 3D innovative technological system of introducing was used to applicate Brigade 3Rive 3D, SC formulation. Field experiments on the study of working conditions when using the pesticide were conducted in various soil and climatic regions of Eastern Europe. Statistical processing of the results was carried out using a package of licensed statistical programs IBM SPSS StatisticsBase v.22 and MS Excel. Research results and discussion. During the conducted research, no bifenthrin contamination was found on the open skin of the operator and the tractor driver, who were processing corn crops with the Brigade 3Rive 3D, SC formulation. However, the operator's gloves were found to contain 0.025 mg of bifenthrin. Calculation of the unitless CASd value on the possibility of skin acute effects when applying the formulation showed that bifenthrin and the Brigade 3Rive 3D, SC formulation based on it are characterized by sufficient selectivity of action on the target object (CASd – 645 and 162, respectively, i.e. > 100) and a low level of danger acute dermal toxic effects for workers, which is due to low values of effective consumption rates. The real dermal risk of bifenthrin exposure when using the Brigade 3Rive3D, SC formulation was significantly lower compared to the risk of workers involved in “traditional” air treatment and treatment with unmanned aerial vehicles (UAVs) (p=0.009-0.048 according to Wilcoxon's W-criterion); in comparison with rod and fan processing – it is non-significantly lower (р=0.262-1.000). There was a similar picture in comparison with the dermal aggravated risk – significantly lower in comparison with the risk of workers involved in “traditional” air treatment and processing with the help of UAVs (p=0.009 according to Wilcoxon's W-criterion); in comparison with rod and fan treatment – non-significantly lower (р=0.262-1.000). Conclusion. It was established that the studied active substance bifenthrin and the Brigade 3Rive 3D, SC formulation based on it are characterized by sufficient selectivity of dermal action on the target object and a low probability of acute dermal effects. A higher probability of acute inhalation poisoning than dermal exposure was revealed.

Precision Agriculture: Assessment of Ergonomic Risks of Assisted Driving System

Background: the precision agriculture field optimizes resource use, enhancing performance. However, this leads to exposure to ergonomic risks for operators, in particular, tractor drivers, potentially causing musculoskeletal disorders (MSDs). This study investigates how the display position in a semi-automatic tractor system influences operator comfort and muscle activation during harrowing operations. Methods: the assessment of muscular strain involved the use of surface electromyographic devices, while posture was evaluated throughout the analysis of the distribution of pressure exerted by the operator’s body on the seat, which was observed using two barometric pads, each positioned on the backrest and base of the seat. Finally, infrared thermography (IRT), a non-invasive tool to assess muscle activation, was used to measure the surface temperature of the driver’s back. The results showed a significantly greater muscular activation display for the position of display in semi-automatic driving at 50° and 80°. Conclusions: this study showed how the position of the display on the vehicle negatively influences posture, exposing workers to the risk of developing fatigue and, therefore, discomfort, with the potential onset of MSDs. The combined use of sEMG and IRT allowed for a non-invasive, cheap, and repeatable mechanical and functionality analysis.

Дефицит кадрового обеспечения сельскохозяйственной сферы юга России 1920-1930 гг

The article is devoted to the analysis of the need for staffing of agricultural workers that developed during the period of collectivization in the south of Russia. The territorial framework of the problem under consideration covers the macro-region of the North Caucasus Region within the Rostov Region and Krasnodar Territory. Analysis of documentation and statistical data revealed a number of specialties that collective farms were particularly in need of. The following qualified personnel were required: agricultural technicians, machine operators and tractor drivers, accountants and accountants, as well as farm managers. At the same time, the training and education of these specialists had to take place under the strict supervision of the party. Training and retraining of personnel required not only professional qualities, but also political literacy. The authorities decided to eliminate the shortage of personnel in two ways. In the article, the author analyzes these ways and through the analysis and introduction into circulation of new archival and statistical materials identifies the most successful. In the course of the study, methods of analysis, comparison and chronology were applied. The author states that by the end of collectivization, literally in 4 years, the problem of labor shortage was not as acute as before. The most effective way to solve the problem of shortage of qualified personnel was the way of training and retraining of agricultural workers. The sources of the article were previously unpublished materials of the State Archive of the Rostov Region and the Centers of Documentation of the Modern History of the Rostov Region and the Krasnodar Territory.

The response from colleagues in the sweet eye estate environment towards women and work as female tractor drivers received a positive response.

Traktör Kazasına Bağlı Yaralanmaların Analizi: On Yıllık Retrospektif Çalışma

Objective: Although tractors are highly inadequate in terms of safety equipment compared to other vehicles, they are still frequently employed for agricultural activities and even human transportation. This study investigated patients presenting to the emergency department (ED) due to tractor accidents.
 Material and Methods: Tractor accidents occurring over a ten year period were examined retrospectively. Victims’ demographic data, the cause of the accident, trauma scores (Glasgow Coma Score, Injury Severity Score, Revised Trauma Score and Pediatric Trauma Score), injury localizations, imaging results, and clinical outcomes were recorded.
 Results: One hundred sixty-five patients were included. Their mean age was 46.48±23.24 years, 82.4% were men, and 41.8% were tractor drivers. The most frequent cause of accidents was “falling from the tractor”. The thorax was the most frequently injured anatomical region. Rates of head and thoracic injury were significantly higher in drivers compared to passengers (p=0.005 and p=0.039, respectively). The post-accident exitus rate was 3.6%. The incidence of abdominal and pelvic injuries was significantly higher in the exitus group than in the survivors (p=0.018 and p=0.015, respectively). Glasgow Coma Score and Revised Trauma Score levels were significantly lower in the exitus group than in the survivors (p

A Survey on the Sleep Quality in Agricultural Tractor Drivers in Different Climatic Conditions

Background and Objectives: Among the various agricultural activities, working and driving with farm tractors in different weather conditions lead to fatigue and burnout. The objective of this study was to evaluate the sleep quality of farm tractors drivers in different weather conditions.
 Methods: Amongst tractor drivers in Behbahan, Eqlid, and Kavar, 90 participants (Kavar: 27; Eqlid: 33; Behbahan: 30) were selected. The required data was gathered using the demographic characteristics questionnaire and standard questionnaire Pittsburgh Sleep Quality Index (PSQI). We used Kruskal-Wallis and Post-hoc pairwise comparison tests to analyze the data (α = 0.05).
 Results: The results showed that there were no significant differences in sleep quality and sleep quality parameters between different region tractors drivers (P > 0.05); but there were significant differences in mental sleep quality (P = 0.001), in terms of delays in falling asleep (P = 0.02), going to sleep duration (P = 0.04) and between Kavar and Behbehan tractor drivers, and also there are significant differences in going to sleep duration (P = 0.04) between Kavar and Eqlid tractor drivers.
 Conclusion: Working in critical cold weather (like nights in Eqlid) or critical hot weather (like noon in Behbahan) should be strongly forbidden by providing with a suitable working schedule especially while tractor drivers without driver’s cabin. Drivers’ cabins safeguards drivers against temperature, wind and dust, and, therefore increase their comfort and sleep quality.

The Effect of Diesel Fuel Additives on the Exhaust Gases of Agricultural Tractors During Plowing

The research aims to study the effect of the fuel type, plow types, and engine speeds on carbon monoxide (CO), hydrogen sulfide (H2S), and oxygen (O2) gases. The field experiments were conducted on an experimental farm in Al-Hamdaniya, Nineveh, Iraq. The investigation was factorial, using a Randomized Complete Block Design with Split –Split plot Design. The three types of fuel were placed in the main plot, the plow types in the secondary split plot, and the speed engine in the Split –Split action. The results showed significant differences between the fuel, plows, and engine speeds in most studied traits. There were no significant differences in the interaction between the plow types and the engine’s speed regarding CO emissions at the two levels. Still, the rate at 1000 rpm recorded the lowest emission value. At the two levels (the level of the exhaust nozzle - the status of the tractor driver’s seat), it amounted to 39.833-18.767 ppm, respectively. Moreover, the highest reading of H2S gas emissions was recorded with diesel without added fuel and the moldboard plow. Finally, the results showed no significant difference, as diesel fuel with super additives from Manol and an engine speed of 2000 rpm recorded the lowest emission rate for the emission rate of O2 gas, amounting to 20.550%.

Indicators of the functional state of the circulatory system among agricultural machine operators

Introduction. Identification of functional disorders and prenosological conditions of the circulatory system under the conditions of adverse effects of the occupational environment is a necessary link in the development of measures to prevent health disorders in workers.
 Materials and methods. The study of functional indicators of hemodynamics, endurance and efficiency, functional reserves of the circulatory system, and ECG dispersion mapping using “Cardiovisor-06s” in eighty five male tractor drivers in agricultural production (agricultural machine operators) was carried out. 
 The average age of the surveyed cases was 42.36±1.2 years, the average work experience in the occupation is 19.61±1.26 years.
 Results. Agricultural machine operators, whose working conditions are characterized by the influence of working environment factors with a prohypertensive effect, have been established to reveal changes in the indicators of the functional state of the circulatory system and a decrease in the adaptive capabilities of the body, indicating the manifestation of borderline states between the norm and pathology. Between the duration of work experience in the occupation and the level of functioning of the circulatory system, a statistically significant correlation was established (r = 0.53) According to ECG dispersion mapping, individual values of the “Myocardium” microalternation index in 14.3% of the examined cases corresponded to a borderline state close to the initial stage of probable pathology . The most pronounced changes, indicating a violation of cardiometabolic processes, were noted in workers over 40 years. The average values of the “Rhithm” index (RI), which characterizes the integral component of heart rate variability, which is a marker of the adaptive capabilities of the body, were in the range of 21–35% for all examined persons (with a normal value of 0–20%), which corresponded to an increased tension of regulatory systems or 
 a borderline state. Increased individual levels of RI were more often recorded in people over 50 years.
 Limitations on the study are determined by the area of studying the subject of research in one professional cohort of workers.
 Conclusion. Early detection of prenosological changes in systemic hemodynamics and adaptation of the circulatory system can be one of the tools to identify the risk group of workers who need to develop and implement measures to prevent diseases of the circulatory system.

ОСОБЕННОСТИ ДИНАМИКИ И СТРУКТУРЫ ПРОФЕССИОНАЛЬНОЙ ЗАБОЛЕВАЕМОСТИ В РЕСПУБЛИКЕ ТАТАРСТАН

Introduction. In their labor activities, employees are exposed to some hazardous and harmful factors of the working environment, of which the key ones are physical factors, such as noise or local/general vibration; physical and functional overloads of the musculoskeletal system; aerosols of predominantly fibrogenic action; and dust. The core indicator characterizing the occupational risk of a health problems is occupational morbidity. Aim. Studying the time profile and structure of occupational morbidity in employees of the Republic of Tatarstan. Material and methods. Occupational morbidity over the years 2007-2021 was analyzed. Over the period under research, occupational illnesses were diagnosed in 2,546 employees of 130 occupational categories. Results and discussion. The highest rates of occupational morbidity were recorded among employees of agricultural and mechanical engineering enterprises and companies. About 60% of occupational diseases were diagnosed in those pursuing 7 professions. What stands out is the similarity of occupational pathologies in assembly workers and riveters, fettlers, and farm-machine operators, who were diagnosed with vibration syndrome and occupational deafness. Occupational diseases of respiratory and musculoskeletal systems were additionally diagnosed in fettlers. In milkmaids, the occupational diseases of musculoskeletal system take the leading place. Polymorbidity of occupational pathology is most pronounced in machine milking operators followed by tractor drivers and fettlers. Conclusion. It is necessary to ensure early occupational pathology diagnoses in routine health screenings and timely referrals to the occupational pathology center in order to perform causal relationship assessments between disease and occupation.

Vibration comfort assessment of tractor drivers based on sEMG and vibration signals

In order to comprehensively evaluate the driver’s vibration comfort under different vibration conditions, eighteen subjects were required to drive a tractor at different speeds on field and asphalt roads respectively in the real vehicle experiment. The sEMG signals and vibration acceleration signals of the subjects were recorded. And the time-frequency domain analysis of sEMG signals and acceleration signals were used to determine the relationship among the characteristic indexes, tractor speed and road surfaces. The relevance analysis showed that there was a significant correlation between the integral electromyography (iEMG) and median frequency (MF) of the middle scalene muscle, erector spinae muscle and gastrocnemius muscle, the RMS of weighted acceleration (aw) of the neck, waist and legs, and the subjective comfort feelings. It was proven that the tractor speed had a significant impact on human body vibration based on the ANOVA result (p < 0.05). With the increase of running speed, the time domain indexes of sEMG signals including iEMG, RMS and the vibration acceleration signals of the testing body parts increased significantly, while the amplitudes of frequency domain indexes decreased. Therefore, a quantitative regression evaluation model for the comfort of the neck, waist and legs integrating the sEMG and vibration signals was established, and its relative errors were 5.05, 4.38 and 6.12% respectively. This proposed assessment model can combine characteristics of the partial and overall vibration response of human body effectively, predict the tractor driver’s vibration comfort accurately, provide a theoretical basis for the evaluation of tractor cab vibration comfort.

Analysis of Injuries and Cause of Death in Fatal Accidents with Farm Tractors

Abstract Farm tractor accidents are a frequent cause of death for people in agricultural field of work. The aim of this study was to evaluate the characteristics of the fatal farm tractor accidents, as well as the most significant types of injuries and causes of death. Research is based on epidemiological criteria of subjects, traffic participation, cause of death, distribution of injury, outliving period and toxicological details. The study included 22 (4.2%) farm tractor related fatalities out of all 525 subjects who died from sustained injuries or complications of the injuries sustained in road traffic accidents. The highest number of deaths was reported in men in 95.5%. The highest percentage died of bleeding out (41%), while in 18% of cases, complications that occurred during the outliving period were the cause of death. Analyzing injuries through organ systems, it is observed that the highest number of farm tractor drivers had a chest injury (90%), and the most common chest injury was a rib fracture (82%). When determining the outliving period, the highest number of fatal farm tractor drivers died at the scene of accidents (68.2%). Of all of the subjects, 32% were under the influence of alcohol, while 23% had blood alcohol concentration level greater than 0.5 ‰. The high mortality of farm tractor drivers can be reduced by introducing a mandatory rollover protective structures system and the use of a seat belt in farm tractors with cabs, which would reduce the possibility of the driver falling out of the farm tractor seat and additional injuries due to rollover.

Самоотверженный труд советского крестьянства в годы Великой Отечественной войны (1941–1945 гг.)

The article discusses the selfless feat of Soviet peasants in providing the front and the population with food and agricultural raw materials. It turned out that overnight food and agricultural raw materials became a strategic commodity for the population of the USSR and the Red Army, the front relied on their timely supply Legal documents are considered: Order of the People’s Commissariat of Trade of the USSR No. 275 of July 16, 1941; order of the Ministry of Trade of the Moscow City Executive Committee on the introduction of cards for some food and industrial goods in Moscow. July 16, 1941, No. 289; resolution of the Leningrad Regional Executive Committee of July 17, 1941, No. 66; resolution of the Council of Ministers of the USSR, Central Committee of the CPSU(b) of December 14, 1947, No. 4004. It turned out that in difficult conditions, every extra kilogram of bread in excess of the norm (plan) was given at a huge cost to the enormous loads that fell on agricultural workers. It is noteworthy that due to the shortage of able-bodied population, child labor was used everywhere, there was a special shortage of specialists: drivers; combine harvesters; tractor drivers; livestock breeders. It turned out that the main and obvious result of the peasants’ labor during the war was the uninterrupted supply of food to the army. Despite all the losses and difficulties, the Soviet people managed to concentrate the necessary amount of resources and products in the hands of the state and provide for all basic needs.

Assessment of Body Discomfort and Physiological Cost of Tractor Drivers during Tillage Operation with MouldBoard Plough

Field experiments were conducted in Al-Muthanna Province, Iraq in order to evaluate the Body parts discomfort score and physiological cost of tractor operator during tillage operation while using mould board plough. Three subjects represented 50th percentile of their population were chosen for this study. We used the Corlett and Bishop Technique to evaluate the degree of discomfort in various body parts. According to the findings, both BPDS and HR went up as the engine rpm went up. The most common sites of pain were the neck, lower back, both legs, both feet, and both wrists. The minimum mean of BPDS was 18.90 at tillage depth 10 cm and engine speed 1000 rpm. While the maximum of BPDS was 28.67 at tillage depth 30 cm and 2000 rpm tractor engine speed. The variation in BPDS due to tillage depth and tractor engine speed was significant at 5 per cent level. The lowest value of HR of the operator was obtained at 10 cm depth and 1000rpm whereas the highest value was obtained at 30 cm and 2000 rpm tractor engine speed. The values were 88 and 101 beats/min respectively. Tillage operation with a mould board plough was associated with a “low” workload in steady state, as seen by the observed HR values for all participants, with the exception of 30 cm depth at 2000 engine speed, where the effort was moderate. The variation in ΔHR due to tillage depth and tractor engine speed was significant at 5 per cent level.

Internet of agriculture: Analyzing and predicting tractor ride comfort through supervised machine learning

The aim of this study is to improve ride comfort among tractor drivers by utilizing Internet of Things (IoT) technology and Machine Learning (ML) techniques to analyze and predict vibration exposure. The study explores the association between tractor ride characteristics, including average speed, tool depth, and pulling force, and ride comfort during actual rotary soil tillage operations. Ride comfort was evaluated by calculating the Overall Vibration Value (OVV) at three measurement locations (i.e., the floor, seat pan, and seat backrest). The study employed spectral analysis i.e., Fast Fourier Transform (FFT) and Power Spectral Density (PSD) to determine the predominant resonant frequencies. In addition, ML approaches i.e., Linear Regression (LR), Decision Tree Regressor (DTR), Support Vector Regression (SVR), Gaussian Process Regression (GPR), and Artificial Neural Network (ANN) were used to predict ride comfort response. Three hyperparameter optimization techniques, including Grid Search, Random Search, and Bayesian optimization were used. Tractor-tiller system was operated on a real agricultural field by five male tractor drivers. Vibration levels were measured along three translational axes at three measurement locations using a smart monitoring device based on the IoT concept. Average OVV magnitude was computed as 0.84 m/s2 i.e., exceeding the ISO 2631-1 (1997) threshold limits. FFT and PSD analysis revealed a variety of dominant frequencies, including resonance peaks at 2 Hz, 6–7 Hz, and 9–11 Hz. The analysis of variance (ANOVA) indicates that tractor speed and tool depth are significant variables (at the 5% level) in determining ride comfort. Regarding predictive accuracy, the ANN model exhibits the highest coefficient of determination of 0.90, followed by the SVM and GPR models with a coefficient of determination of 0.89. The DTR and LR models demonstrate slightly lower coefficient of determination values of 0.83 and 0.82, respectively. Furthermore, Bayesian optimization proved to be an effective approach in achieving more accurate predictions of tractor ride comfort. In general, the study outcomes can be utilized by tractor designers in numerous ways to optimize tractor design (such as suspension system, cab design, seat design, etc.) to improve tractor ride comfort in real field applications.
