Servicing the Blade Plane

The rotary deck comes from the factory preset at 2.00
inch (5 cm) height-of-cut and blade rake of 0.310 inch
(7.9 mm). The left-hand and right-hand heights are also
preset to within ±0.030 inch (0.7 mm) 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) (Figure 12) and measure height from table
to cutting edge of blade.

5. Rotate the marked end of the blade to the 3 and
9 o'clock positions (Figure 12) and measure the
heights.
6. Compare the 12 o'clock measured height to the
height-of-cut setting. It should be within 0.030 inch
(0.7 mm). The 3 and 9 o'clock heights should be
0.150±.090 inch (3.8±2.2 mm) higher than the 12
o'clock setting and within 0.090 inch (2.2 mm) of
each other.
If any of these measurements are not within
specification, proceed to Adjusting the Blade Plane.
Adjusting the Blade Plane
Start with the front adjustment (change one bracket at a
time).
1. Remove the height-of-cut bracket, (front, left, or
right) from the deck frame (Figure 13).
2. Adjust 0.060 inch (1.5 mm) shims and/or 0.030 inch
(0.7 mm) shim between the deck frame and bracket
to achieve the desired height setting (Figure 13).
