Track widths
The tractor can be equipped with adjustable, reversible wheel discs that allow the track
width to be changed.
Whenever the wheels are reversed, check to make sure that the arrows indicating the
turning direction on the tyre are pointing in the correct direction.
The overall width of the tractor is governed by laws when the tractor is driven on the
roads: comply with the laws in force in the country of use.
WARNING: When disassembling the tyres:
• Take the greatest care
• Use tools and equipment that set the tractor in safe conditions
• Use tools to lift heavy wheels.
Wheel bolt torque values
A The driving torque to fix the flange to the
disc is:
ø 12” = 10Kgm (98Nm)
ø 15”/16” = 15Kgm (147Nm)
ø 18”/20”/24” = 25Kgm (245Nm)
B The driving torque to fix the wheel disc to
the hub is:
Front (M14X1.5) = 15Kgm (147Nm)
Rear (M16X1.5) = 22Kgm (215Nm)
Transmission ratio
The ratio between the tip speed of the front
and rear wheels must be accurately
determined so that the front wheels are in
advance. failing this, the tyres will be
subjected to excessive wear.
sk your dealer for advice when you
change the size of tyres.
