Leveling the Mower Deck

Setting Up the Machine
Note: Ensure the mower deck is leveled before matching the
height-of-cut (HOC).
1. Position mower on a flat surface.
2. Disengage the blade control switch (PTO), move the
motion control levers to the neutral locked position
and set the parking brake.
3. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
4. Check tire pressure of the tires. If needed, adjust to
90 kPa (13 psi).
5. Position the mower to the 76 mm (3 inch) height-of-cut
position.
Deck Leveling
1. Position the mower on a flat surface.
2. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
3. Check the tire pressure in the drive tires. Proper
inflation pressure for tires is 90 kPa (13 psi). Adjust
if necessary.

5. Push the deck lift pedal all the way forward and the
deck will latch at the 14 cm (5-1/2 inch) transport

6. Insert the height adjustment pin into the 3 inch (7.6
cm) cutting height location.
7. Release the transport lock and allow the deck to lower
to the cutting height.
8. Raise the discharge chute.
9. On both sides of the deck, measure from the level
surface to the front tip of the blade (Postion A). The
measurement should read 3 inches (7.6 mm) (Figure
72).
1. 3 inches (7.6 cm) at A is
correct
2. 3 1/4 inches (8.3 cm) at B
is correct
10. If needed, loosen the whizlock nut on the side of the
yoke and the jam nut on top. Fine tune the screw
adjuster by turning it to get 3 inch (7.6 mm) height (see
Figure 73).
To increase the height, turn the adjuster screw
clockwise; to decrease, turn counterclockwise.
