Adjusting the Skids
The skids should be mounted in the lower position when
operating in height of cuts greater than 2-1/2 inches
(64 mm) and in the higher position when operating in
height of cuts lower than 2-1/2 inches (64 mm).
Adjust the skids by removing the flange bolt and nuts,
positioning them as desired, and installing the fasteners
(Fig. 15).

must be repositioned in the top bracket holes.
To adjust the front rollers (Fig. 16)
1. Remove the screw and nut securing the roller shaft to
the deck bracket (Fig. 16).

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 22.
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.
