3. To adjust distance, locate adjuster bolt on rear pivot
link of cutting unit
adjuster bolt. Loosen or tighten adjuster bolts until
10-16 mm (0.38-0.62 inch) clearance is attained, then
tighten jam nut.
4. Repeat procedure on opposite side of cutting deck.

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 (page
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
Blade (page 55).
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
Height-of-Cut (page 27)
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
