Correcting Mismatch Between
Cutting Units
Due to differences in grass conditions and the counterbalance
setting of the traction unit, it is advised that a sample area
of grass be cut and the appearance checked before formal
cutting is started.
1. Set all cutting units to the desired height of cut; refer to
Adjusting the Height of Cut.
2. Check and adjust front and rear tractor tire pressure to
172-207 kPa (25-30 psi).
3. Check and adjust all castor tire pressures to 345 kPa
(50 psi).
4. Check charge and counterbalance pressures with
engine at high idle using test ports defined in Hydraulic
Systems Test Ports. Adjust counterbalance to 2241
kPa(325 psi).
5. Check for bent blades; refer to Checking for a Bent
Blade.
6. Cut grass in a test area to determine if all cutting units
are cutting at the same height.
7. If cutting unit adjustments are still needed, find a flat
surface using a 2 m (6 foot) or longer straight edge.
8. To ease measuring blade plane, raise the height of cut
to 7.6 to 10.1 cm (3 to 4 inches); refer to Adjusting the
Height of Cut.
9. Lower cutting units onto the flat surface. Remove the
covers from the top of the cutting units.
10. Loosen the flange nut, securing the idler pulley, to
release the belt tension on each cutting unit.
Front Cutting Unit Setup
Rotate 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 height of cut to decal

Side Cutting Unit Setup
Rotate blade of 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
arm(s) to match height of cut to decal
outside blade spindle only, refer to Adjusting the Cutting Unit
Pitch.

Matching Height Of Cut Between Cutting Units
1. Position blade side to side on outside spindle of both
side cutting units. Measure from the floor to the tip of
the cutting edge on both units and compare. These
numbers should be within 3 mm (1/8 inch) of each
other. Make no adjustment at this time.
2. Position blade side to side on inside spindle of side
cutting unit and corresponding outside spindle of front
cutting unit. Measure from the floor to the tip of the
