AbstractA field experiment was conducted in the experiment fields of the college of agriculture - University of Baghdad – Abu Ghraib , 2016 in a silt clay loam soil , to Evaluate the effect of some primary tillage equipment and two of levels of soil moisture content in some of performance efficiency indicator for different forward speed , ArmaTrac 845e and ITM 285 New tractor with moldboard and chisel and sweep plow as a machinery unit have been used in this study .
Two levels of soil Moisture content include (18 – 20 % ) and (14 – 16%) represented main plot , three types of plow ( moldboard , chisel and sweep) represent sub plot , five machinery speeds included ( 1.5 , 2.53 , 3.75 , 5.3 and 6.71 km.hr-1 ) represent sub plot , Slippage percentage (%) , fuel consumption (L.hr-1) , drawbar pull (KN) , Field capacity (he.hr-1) are have been been measured in this study . And the results have been analyzed by using the order of the spilt - spilt - plot with randomize complete block design with three replicates and tested by the way averages less significant difference and the level of probability of 0.05 .
The results show that : the soil moisture content ( 14 – 16 % ) has got a less value of slippage percentage % , fuel consumption L.hr-1 , drawbar pull Kn and higher field capacity ha.hr-1 , and sweep plow has got a less value of slippage percentage , fuel consumption and drawbar pull , and the chisel plow has got a higher field capacity , and when the tractor speed is increased it leads to a increase in the slippage and fuel consumption and drawbar pull and field capacity will be an increase .-1.
