2. Align the roller and spacer with the top holes in
the brackets and secure them with the bolt and
nut.
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 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 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
Bent Blade (page
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 (page
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.
