The effect of some operating parameters on field performance of tractor

الملخص EN

This study using two levels of plow types (mould board and standard disc), three levels of the wheel pressure (2.5, 2 and 1.5) bar and three levels of the forward speed (3.94, 7.49 and 9.59) km/h, the impact of these treatments in the characters of the slipping, field efficiency and productivity was measured .

The results indicated that the interaction between the treatments had a significant impact in some of these characters, the mould board plow, wheel pressure (1.5 bar) and forward speed ( 3.94 km/h) is superiority in other treatments in the character wheel slipping which was ( 8.74 % ) , while the treatment superiority mould board plow, wheel pressure (2 bar) and forward speed ( 7.49 km/h) on the other treatments in the characters of field efficiency and productivity which was ( 77.94 % , 0.67 ha/h ) respectively.
