Mower Deck Maintenance; Leveling The Mower Deck - Toro 74311TE Operator's Manual

Every 500 hours—Change the hydraulic filter
and reservoir hydraulic fluid when using Toro
™
HYPR-OIL 500 hydraulic fluid (more often in dirty
or dusty conditions).
Note: Use a summer filter when the temperature is 0° C
(32° F) and above. Use a winter filter when the temperature is
0° C (32° F) and below.
1. Move the speed control lever to the N
to stop the machine.
2. Disengage the PTO, engage the parking brake, shut off
the engine, and wait for all moving parts to stop.
3. Carefully clean the area around the filter.
Important: Ensure that no dirt or contamination
enter the hydraulic system.
4. Unscrew and remove the filter and allow the fluid to
drain from the reservoir.
Note: Do not change hydraulic system fluid (except
for what can be drained when changing the filter),
unless it is felt the fluid has been contaminated or
been extremely hot. Changing the hydraulic fluid
unnecessarily could damage the hydraulic system by
introducing contaminates into the system.
5. Before installing the new filter, fill it with Toro
™
HYPR-OIL 500 hydraulic fluid and apply a thin coat
of fluid on the surface of the rubber seal.
6. Turn the filter clockwise until the rubber seal contacts
the filter adapter, then tighten the filter an additional
2/3 to 3/4 turn.
7. Fill the reservoir as stated in
Fluid (page 51).
8. Raise the rear of machine up and support with jack
stands (or equivalent support) just high enough to
allow drive wheels to turn freely.
9. Start the engine and move the throttle control ahead to
full throttle position.
10. Move the speed control levers to the full speed position
and run the machine for several minutes. Shut down
the machine and check the fluid level.

Note: Ensure that the mower deck is leveled before
matching the height of cut (HOC).
1. Position the machine on a flat surface.
2. Move the speed-control lever to the N
to stop the machine.
3. Disengage the PTO, engage the parking brake, shut
down the engine, and wait for all moving parts to stop.
4. Check the tire pressure of the drive tires. If needed,
adjust the pressure to 103 kPa (15 psi).
Leveling the Deck

3. Verify all hairpin cotters are in the 7.62 cm (3 inch)
mower deck height holes with the spacers under the
hairpin cotters (Figure

4. Shorten or lengthen each mower deck support pin to
obtain blade tip height of 7.62 cm (3 inches) at the
front of the deck and 8.26 cm (3 1/4 inches) at the rear
of the deck (Figure
Note: The front pins are thread into the mower deck
and have a jam nut. The rear pins have a rod end
threaded into them with a jam nut.
