| Abstract | ||
| r 80 tractor to investigate the effect different levels of tires pressure on the field performance when field experiments by using the mold oard plough in three depths ( 10, 15, and 20 ) cm for loading Antar 80 tractor.four front speeds (0.48, 0.76, 1.20, 1.68) m/sec., and three levels of air pressure for forward tires of (0.75,1, 1.5) bar were employed .The experiments were carried out in silty lay soil . The results showed on increase in the roll resistance with increasing the forward speed from 0.48 to 1.68 m/sec . when the forward tires pressure was 1 bar , the roll also increased with an increased forward speed. The result indicated that the 1 bar pressure gave lower roll resistance while the pressures 0.75 and 1 bar gave lower roll than that of 1.5 bar . The lack in the ability ( power) was lower at in the 1 bar than that at other pressures .The pressure 1 bar was the best and gave high tractive efficiency which equal to( 0.74 , 0.78, 0.71) for the air pressures ( 1.5, 1, 0.75) bar respectively . | ||
