Adjusting The Skids; Adjusting The Cutting Unit Anti-Scalp Rollers - Toro 31598 Operator's Manual

Figure 28
Note: When operating at 64 mm (2-1/2 inch) height
of cut or higher, the axle bolt should be installed in
the bottom castor fork hole to prevent grass buildup
between the wheel and the fork. When operating at
heights of cut lower than 64 mm (2-1/2 inch) and grass
buildup is detected, reverse the machines direction to
pull any clippings away from the wheel/fork area.
3. Remove the tensioning cap from the castor spindle
shaft (Figure 29) and slide the castor shaft out of
the castor arm. Put 2 shims (1/8 inch [3 mm]) onto
the shaft as originally installed. Slide the appropriate
number of 1/2 inch spacers onto the shaft to get the
desired height-of-cut.
Note: The shim washers may be used in any
combination above or below the castor arm hub as
required to achieve the desired height of cut or deck
level.

Adjusting the Skids

The skids should be mounted in the lower position when
operating at heights of cut greater than 64 mm (2-1/2 inch)
and in the higher position when operating at heights of cut
lower than 2-1/2 inches (64 mm).
Note: When the skids become worn, you can switch the skid
to the opposite sides of the mower, flipping them over. This
will allow you to use the skids longer before replacing them.
1. Loosen the screw at the front of each skid

2. Remove the flange-head bolts and nuts from each skid
(Figure 30).
3. Move each skid to the desired position and secure them
with the flange-head bolts and nuts.
Note: Only use the top or center sets of holes to
adjust the skids. The bottom holes are used when
switching sides at which time they become the top
holes on the other side of the mower.
4. Torque the screw at the front of each skid to 9 to 11
N-m (80 to 100 in-lb).
