Servicing the Blade Plane

The cutting unit comes from the factory preset to a 5 cm
(2.00 inch) height of cut and a blade rake of 7.9 mm ( 0.310
inch). The left and right heights are also preset to within +/-
0.7 mm (0.030 inch).
The cutting unit is designed to withstand blade impacts
without deformation of the chamber. If a solid object is
struck, inspect the blade for damage and the blade plane for
accuracy.
Inspecting the Blade Plane
1. Remove the hydraulic motor from the cutting unit and
remove the cutting unit from the traction unit.
2. Use a hoist (or minimum of 2 people) and place the
cutting unit on a flat table.
3. Mark one end of the blade with a paint pen or marker.
Use this end of the blade to check all heights.
4. Position the cutting edge of the marked end of the
blade at 12 o'clock (straight ahead in the direction of
mowing) and measure height from table to cutting edge
of blade (Figure
9:00
5. Rotate the marked end of the blade to the 3 and 9
o'clock positions and measure the heights
