Leveling The Mower Deck - Toro 74381 TimeCutter Z4202 Operator's Manual

Leveling the Mower Deck

Check to ensure the mower deck is level any time you
install the mower or when you see an uneven cut on
your lawn.
The mower deck must be checked for bent blades
prior to leveling; any bent blades must be removed
and replaced. Refer to the Checking for Bent Blades
procedure before continuing.
The mower deck must be leveled side-to-side first then
the front to rear slope can be adjusted.
Requirements:
• The machine must be on a level surface.
• All four tire must be properly inflated. Refer to
Checking the Tire Pressure in the Drive System
Maintenance section.
Side-to-Side Leveling
1. Park the machine on a level surface and disengage
the blade control switch.
2. Move the motion control levers outward to the
park position, stop the engine, remove the key, and
wait for all moving parts to stop before leaving the
operating position.
3. Set the height-of-cut lever to middle position.
4. Carefully rotate the blades so that they are all side
to side (Figure 48).

6. Move to the left side of the machine. Loosen, but
do not remove, the rear locking nut on the hanger
bracket (Figure 49).
7. Loosen the side locking nut on the hanger bracket
just enough to allow the eccentric plate to be adjusted
(Figure 49). Use a 3/8 inch drive extension on a
socket wrench to manipulate the eccentric plate. Use
the wrench to reposition the height of the mower
deck and adjust to the desired height.
8. Stop the deck at the adjusted position and tighten the
side locking nut on the hanger bracket to hold the
new position (Figure 49). Tighten the rear locking
nut on the hanger bracket.
9. Continue leveling the deck by checking the
front-to-rear blade slope; refer to Adjusting the
Front-to-Rear Blade Slope.
