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
(Figure 26).

Adjusting the Cutting Unit Rollers
The cutting unit rollers 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).
1. Remove the bolt and nut securing the gage wheel to
the cutting unit brackets (Figure 27).

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.
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 charge and counterbalance pressures
with engine at high idle using test ports defined
in Hydraulic Systems Test Ports. Adjust
counterbalance setting to be 220 psi (1517 kPa)
higher than charge pressure reading.
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 6 foot (2 m) or longer straight edge.
