Engine specification
Tyres
The loader can be equipped with different type of tyres for different operating conditions. Grass pattern (GR) tyres will
damage the ground surface less than tractor (TR) tyres, but provide less traction.
For the best stability and controllability, always use the largest tyres possible. Tyres that are narrower than the standard
tyres are intended for special purposes only with width restriction on the machine. Use only tyres and rims that meet
the original specifications and dimensions to avoid potential issues with load capacity, tyre size, or bearing load on
drive motors. Consult your dealer if further information is needed. Special tyres, such as studded wheels may also be
available. Consult your dealer for further information.
