Abstract

The article presents the results of experimental studies of the soil tillage unit based on a new modular power machine of variable traction class. It includes the universal tractor of drawbar category 1.4 (2.0) and technological unit as an additional bridge, having active drive wheels from synchronous PTO-shaft of the tractor. The new modular power facility with experienced five-part plow has been investigated in wheat stubble plowing. Obtained operational and technological parameters are compared with the same regulatory parameters of the tillage unit as part of a tractor of class 1,4 and a three-part plow. It is found that the performance of a new replaceable unit is 1.9 times higher and the specific fuel consumption is 27.5% less in comparison with the standard unit.
Special laboratory and field experimental studies established the degree of influence of the wheels on the process of compaction of different initial moisture content (12.8…20.8%) after the passage of the wheels of the front and rear axles of the tractor of class 1,4.
