Abstract
An experiment was conducted on the field of the College of Agriculture at Abu-Ghraib in 2011.This was to study some technical parameters for machinery units .The study consisted of two factors: first factor was practical depth with two levels: 10 and 20 cm represented main plots, second factor was tractor speed with two levels(3.11 and 5.61) km/h representing sub plots, . Slippage percentage, practical productivity, field efficiency and soil disturbed volume were studied in this experiment. The results showed that spring cultivator gave best performance in scored higher speed (4.013 Km/hr) while chisel plow scored lower speed( 3.808Km/hr) , spring cultivator gave lower slippage percentage (8.40%), while chisel plow gave higher slippage percentage( 12.81%) . Spring cultivators gave best performance in scored higher practical productivity )0.761ha/hr) while chisel plow scored gave lower practical productivity ) 0.675ha/hr) , spring cultivators gave best performance in scored higher field efficiency (%58.3) while chisel plow scored gave lower field efficiency) 47.4%) , spring cultivators gave best performance in scored higher soil disturbed volume (987 m3/h) while chisel plow scored gave lower soil disturbed volume (888 m3/h).The spring cultivator gave best performance as compared with chisel plow in recording low slippage percentage, higher practical productivity, ,higher field efficiency and higher soil disturbed volume as well ass the depth 10 cm gave best performance in recording low slippage percentage ,higher practical productivity ,higher field efficincy and the slow speed gave the lower slippage percentage.
