Blade Plane
The rotary deck comes from the factory preset at 2.00 inch
height-of-cut and blade rake of 0.31 inch. The left-hand and
right-hand heights are also preset to within 0.03 inch of
the other.
The cutting deck is designed to withstand blade impacts
without deformation of the chamber. If a solid object is
struck, inspect the blade for damage and blade plane for
accuracy.

1. Remove hydraulic motor from cutting deck and remove
cutting deck from tractor.
2. Use hoist (or minimum of two people) and place cutting
deck on flat table.
3. Mark one end of blade with paint pen or marker. Use
this end of blade to check all heights.
4. Position cutting edge of marked end of blade at 12
o'clock (straight ahead in direction of mowing)
(Fig. 10) and measure height from table to cutting edge
of blade.
