Correcting Cutting Unit
Mismatch
Due to differences in grass conditions and the
counterbalance setting of the traction unit, it is advised that
grass be cut and appearance checked before formal cutting
is started.
1. Set the cutting unit to the desired height of cut; refer to
Adjusting the Height of Cut, page 13.
2. Check and adjust front and rear tractor tire pressure to
25–30 psi (172–207 kPa).
3. Check and adjust all castor tire pressures to 50 psi
(345 kPa).
4. Check for bent blades; refer to Checking for a Bent
Blade, page 21.
5. Cut grass in a test area to determine if all cutting units
are cutting at the same height.
6. If cutting unit adjustments are still needed, find a flat
surface using a 6 foot (2 m) or longer straight edge.
7. To ease measuring blade plane, raise the height of cut to
the highest position; refer to Adjusting the Height of
Cut.
8. Lower cutting unit onto the flat surface. Remove the
covers from the top of the cutting units
9. Rotate the blade on each spindle until the ends face
forward and backward.
10. Measure from the floor to the front tip of the cutting
edge.
11. Adjust 1/8 in. shims on castor fork(s) to match height of
cut to decal (Fig. 16); refer to Adjusting the Cutting
Unit Pitch.
