Servicing the Blade Plane
The rotary deck comes from the factory preset at 5 cm
(2.00 inch) height-of-cut and blade rake of 7.9 mm
( 0.310 inch). The left-hand and right-hand heights
are also preset to within ± 0.7 mm (0.030 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 the
blade plane for accuracy.
Inspecting the Blade Plane
1.
Remove the hydraulic motor from the cutting
deck and remove the cutting deck from the
tractor.
2.
Use a hoist (or minimum of two people) and
place the cutting deck 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)
height from table to cutting edge of blade.
