Recently leading producers of farm tractors even more often apply in running systems triangular caterpillar contour (TCC). In such running system one of the most problem knots is the back idler (BI) which is loaded by reaction from a caterpillar track and from weight of the casco having on this support. Thus the vertical component of reaction from a tension of a caterpillar track in addition loads with a tie-rod tangential force suspension bracket BI, thereby disturbing with a casco and reducing smoothness of a course of a tractor. Modelling and the analysis of dependence of affecting of vibration on a seat of the motor-man depending on applied type of a suspension bracket of a back idler are in-process executed. The analysis of parameters of smoothness of a course for the circuit design with triangular caterpillar contour and the offered suspension bracket of a back idler showed that in comparison with base configuration of a tractor of family VT On transport operations, at traffic on the soil road with the lifted tool, affectings on a seat of the operator decrease in 1,1-1,7 times in vertical and in 1.1-1.2 times in horizontal directions, at work with nominal loading, and also with Rkr=50 kN, on an eddish, provides minor alteration of smoothness of a course, the divergence of values of affecting on a seat of the operator, on the average, makes 12–19 %. In comparison with triangular caterpillar contour and "a classical" suspension bracket of a back idler, various displacement-yoke systems of a back idler, at work on transport operations, slightly influence a divergence of parameters of affecting on a seat of the operator which make 2.6 % and 4 % for vertical and horizontal affectings accordingly. At work with nominal loading on an eddish, affectings on a seat of the operator decrease in 1.7–2.7 times in vertical and in 1.4–1.8 times in horizontal directions and at work with draw-bar loading of Rkr=50 kN on an eddish, affectings on a seat of the operator decrease in 1.4–2.1 times in vertical and periodically increase on some speeds no more than by 30 % in a horizontal direction.
