Changing Gear Box Lubricant - Toro 30385 Operator's Manual

2. Raise the seat and open the needle valve. This
allows the lift arms to float freely.
3. Adjust the lift arms heights, making sure that the
machined surface on top of each traction unit lift
arm is parallel to the ground (Fig. 11). (Raise or
lower the lift arm casting by pushing up or down
from behind the front tires or by using a wrench in
front of the tractor)
4. Check for dirt and debris on mating parts and clean
as required.
5. Turn the castor wheels so they point straight for-
ward and the deck moves easily toward the tractor.
6. Secure the first lift arm assembly to the traction
unit as follows:
A. Remove the hair pin cotter and clevis pin
securing the latch cover to the lift arm.
B. Pivot the release lever upward.
C. Slide the cutting unit lift arm onto the traction
unit lift arm, inserting the shaft latch into the
slot in the traction unit lift arm.
Note: If the latch does not fall into the slot in
the traction unit lift arm, raise or lower the lift
arm casting by pushing up or down from
behind the front tires.
D. Pivot the release lever downward and tighten
securely by rotating clockwise.
7. Install the other lift arm on the tractor by rotating
the deck toward tractor, aligning the lift arm to
tractor arm and repeating step 5. If the latch does
not fall into the slot in the traction unit lift arm, the
arms are not lined up.
A. If the lift arms on the traction unit are not at
the correct height for deck arms to slide on,
push up or down on the lift arm castings from
behind the front tires until deck arms line up
and slide on.
B. If lift arms on deck do not line up side to side,
rotate the castor wheels side ways so the deck
moves easier from side to side. Move the
deck side to side until the lift arms line up and
slide on.

8. Move the deck from side to side to check for tight-
ness and re-tighten the latches, if required.
9. Install the latch covers to the lift arms and secure
them with clevis pins and hair pin cotters.
10. Connect the drive shaft to the traction unit.
11. Close the needle valve and lower the seat.
12. Start the tractor and raise the deck to the highest
possible position. Then turn off the engine.
13. Align the height-of-cut straps with the hole for
desired height of cut, install the clevis pin and
secure it with a hair pin cotter.
