Study of the feasibility of using doubled or tripled tires of wheeled power vehicles

Goal. To determine and justify the conditions under which use of double/triple tires wheeled energy vehicles instead single ones will be appropriate. Methods. Theoretical studies were carried out using basics theory tractors agricultural machines. The object research was MTZ1221 multipurpose-weed tractor, front axle studied in variants with single, double, triple tires. Soil compaction passage zones these taken as an argument for yield function crop (spring barley). Results. Calculations established that intensity reducing depth wheel track, compacting soil, increasing cultivated barley) higher when a double tire compared to one, lower case replacing one. Due created track reduced. Conclusions. A new analytical dependence obtained, could used evaluating feasibility doubled or tripled reduce their effect on soil correspondingly increase crops. By different numbers example it tire, three-wheel one led decrease by at least 30%, 42%, 2.2 times.
