2. Remove the flange-head bolts and nuts from each skid
(Figure 25).
3. Move each skid to the desired position and secure them
with the flange-head bolts and nuts.
Note: Use only the top or center sets of holes to
adjust the skids. Use the bottom holes when switching
sides, at which time they become the top holes on the
other side of the mower.
4. Torque the screw at the front of each skid to 9 to 11
N⋅m (80 to 100 in-lb).
Adjusting the Cutting-Unit Rollers
The cutting-unit rollers should be mounted in the lower
position when operating in height of cuts greater than 64 mm
(2-1/2 inches) and in the higher position when operating in
height of cuts lower than 64 mm (2-1/2 inches).
1. Remove the bolt and nut securing the gage wheel to
the cutting-unit brackets

2. Align the roller and spacer with the top holes in the
brackets and secure them with the bolt and nut.
(Figure 26).
Correcting Mismatch Between Cutting
Units
Due to differences in grass conditions and the counterbalance
setting of the traction unit, cut and inspect a sample area of
grass before cutting the entire area.
1. Set all cutting units to the desired height of cut; refer to
Adjusting the Height of Cut (page
2. Check and adjust front and rear tractor tire pressure to
172 to 207 kPa (25 to 30 psi).
3. Check and adjust all castor tire pressures to 345 kPa
(50 psi).
4. Check charge and counterbalance pressures with the
engine at high idle, using test ports defined in Hydraulic
Systems Test ports..
5. Adjust the counterbalance to 2241 kPa (325 psi).
6. Check for bent blades; refer to
Blade (page 53).
7. Cut grass in a test area to determine if all cutting units
are cutting at the same height.
8. If cutting unit adjustments are still needed, find a flat
surface using a 2 m (6 foot) or longer straight edge.
9. To ease measuring blade plane, raise the height of cut
to 7.6 to 10.1 cm (3 to 4 inches); refer to
Height of Cut (page
10. Lower the cutting units onto the flat surface.
11. Remove the covers from the top of the cutting units.
12. Loosen the flange nut securing the idler pulley to
release the belt tension on each cutting unit.
Front Cutting Unit Setup
Rotate the blade on each spindle until the ends face forward
and backward. Measure from the floor to the front tip of the
cutting edge. Adjust 3 mm (1/8 inch) shims on front castor
fork(s) to match the height of cut to the decal
