The wheel track of 1500 is adjusted by 
the manufacturer as standard. 
The rear wheel track is adjusted by 
changing the position of the rim and disc 
with the rear part of the tractor lifted.  
The wheels must turn freely.  
Before the lifting do not forget to secure the tractor against moving by wedg-
ing the front wheels! 
After changing the wheel track tighten all the screws connecting the disc with the rim 
with the torque of 200 - 220 Nm and the nuts of the screws connecting the disc with 
the wheel shaft with the torque of 400 - 470 Nm.  
 After every loosening of a rim connection tighten the screws to the prescribed 
value.  
 After driving 100 m with the tractor without load re-tighten the connections with the 
prescribed torque.  
 After loading the tractor re-tighten the connections after 3 hours of work.  
 After 10 hours of work check the tightening of the nuts of discs and wheel rims 
again.  
 Until reaching the first 100 hours of work perform frequent checks of tightening the 
nuts of the discs and rims of the front and rear wheels (at least 6 times in the 
course of the first 100 hours of work).  
 Then, always check the tightening of the nuts of the discs and rims of the front and 
rear wheels after every 100 hours of work.
