The detrimental compacting effect of agricultural vehicles, including tractors, harvesting machinery, transport vehicles and tillage implements, rises parallel with any increase in the capacities and the weight of the vehicles. Today, the detrimental effects can be noted not only in the top layers of the soil but in other layers as well deeper down. One of the methods to eliminate detrimental soil compacting is medium-deep tillage which is becoming more and more widespread these days. Due to variations in the locations of operation and the jobs to be performed, different tillage implement and engine parameters are required. Therefore, research is aimed at selecting the most favourable tillage angle ranges and implement widths. At the same time, a medium-deep tillage implement has been developed in which the clearance between the gusset plates is continuously adjustable in the 425 - 700 mm range. The new implement is capable of fully satisfying varying agrotechnical and energy requirements.
