Maintenance
4. Stop the engine, remove the key and wait for all
moving parts to stop.
5. Blades may be adjusted for cutting height by using
the four 1/4 inch (.64 cm) spacers found on the
blade spindle bolts (factory setting is two above
and two below). This allows a 1 inch (2.5 cm)
range in 1/4 inch (.64 cm) increments of cutting
height in any axle position. The same number
of blade spacers must be used on all blades to
achieve a level cut (two above and two below, one
above and three below, etc.).
6. Raise front of deck and support with jack stands.
7. Hold blade bolt on bottom and loosen spindle
nut on top.
8. Adjust number of spacers between bottom of
spindle and blade as indicated in the Cutting
Height Adjustment Table and notes in the
Adjusting the Cutting Height section.
9. Install unused spacers between top of spindle and
spindle nut.
10. Torque bolt to 75–80 ft-lb (102–109 N-m) (see
Figure 11).

PTO engagement assist arm beneath the front, left
hand corner of the engine deck.
1. Stop engine and wait for all moving parts to stop.
Engage parking brake. Remove key or spark plug
wire(s).
2. With PTO engaged (lever pulled up, adjust the

Figure 12). Make sure the assist arm is against the
rear assist arm stop on the deck (see Figure 13).
Push the lever down to the disengaged position.
The assist arm should contact the front assist arm
stop on the deck. If it does not contact, readjust
so that the bellcrank is closer to the gusset.
