Standard adjustment of the wheel tread by the 
manufacturer is 1,500mm. 
The rear wheels tread can be adjusted by a 
change of position of the rim and disk when the 
rear part of the tractor is lifted. It is necessary to 
ensure free rotation of the wheels. 
Before lifting the tractor do not forget to secure the tractor against any 
movement by chocking of the front wheels! 
After a change of the wheels tread tighten all bolts, connecting the disk with 
the rim, by a torque 200 to 220Nm and the nuts of bolts, connecting the disk 
with the shaft, by a torque 400 to 470 Nm. 
−  After each release of the beed joint tighten the bolts to the prescribed 
torque. 
−  After covering of 100m with unloaded tractor retighten the joints to the 
prescribed torque value. 
−  After loading of the tractor retighten the joints after 3 operating hours. 
−  After 10 operating hours recheck tightening of nuts of the disks and wheel 
rim beeds. 
−  Carry out frequent checks of tightening of nuts of disks and beeds on the 
front and rear wheels within first 100 operating hours (at least 6 checks in 
the course of first 100 operating hours). 
−  Recheck tightening of nuts of disks and rim beeds on the front and rear 
wheels every other 100 operating hours.
