摘要：
Tractor speed, tractor power and tractor tire inflation pressure with different tillage implements were investigated. The influence of the above parameters on travel reduction, drawbar pull, soil resistance to cone penetrometer pressure and soil bulk density was also studied Measured drawbar pull was consistently higher than estimated drawbar pull. Increasing the tire inflation pressure from 83 to 110 kPa increased travel reduction from 12. 6 to 13. 4% while the estimated drawbar pull decreased from 1. 25 to 1. 11 kN for a given tractor. The measured drawbar pull decreased from 2. 21 to 1. 37 kN.
