Abstract
This study aims to develop, construct and field evaluate small-scale mower for grass harvesting. The mower machine is fabricated from local materials which redesign and modify the cutting drum. The results indicated, reducing friction and improved the mower performance, reduce noise, maximize cutting efficiency and minimize energy requirements. The results can be summarized as follows: Maximum effective field capacity of 587.4 m2/h was obtained with forward speed of 2.16 km/h, cutting height of 2 cm and cutting speed of 6 m/s, the maximum cutting-efficiency of 98.8 % was obtained at forward speed of 0.84 km/h, cutting height of 2 cm and cutting speed of 6 m/s, and the maximum specific energy of 11.27 kW.h/fed. was obtained at forward speed of 0.84 km/h, cutting height of 5 cm and cutting speed of 6 m/s.
