Abstract
The dependences of the coefficient of use of the working time of the change of the proposed multifunctional unit for harrowing winter crops with simultaneous additional fertilizing with solid mineral fertilizers are theoretically justified. In the conditions of agriculture of Krasnodar Territory, with an increase in the working speed of the unit, a significant decrease in this coefficient was found for various ruts and capacities of the fertilizer silo. For the proposed unit, all components of the cycle time spent on performing two working and two idle passes through the field with the shuttle method of movement, as well as the number of cycles per shift, the actual duration of the shift time and its utilization rate are calculated. With an increase in the working speed of the unit, all other things being equal, the value of the shift time coefficient decreases.
Highlights
In order to achieve an increase in grain yield, it is necessary to improve the system and methods of tillage, use the most advanced machines
It is possible to create a multifunctional unit in another way by placing several working bodies to perform a certain number of technological operations on one common frame [3, 4]
We have proposed a new multifunctional unit that combines the operations of fertilizing and simultaneous harrowing of crops [5]
Summary
In order to achieve an increase in grain yield, it is necessary to improve the system and methods of tillage, use the most advanced machines. These include multifunctional units (MFUs) and machines.
