Replacing the Transmission
Filter
Change the transmission filter after the first 10 hours of
operation and every 800 hours thereafter.
Only the Toro replacement filter (Part No.75-1330) can be
used in the hydraulic system.
Important Use of any other filter may void the
warranty on some components.
1. Position machine on a level surface, lower the cutting
units, stop the engine, engage the parking brakes, and
remove key from ignition switch.
2. Clean area around filter mounting area (Fig. 67). Place
drain pan under filter and remove filter.
3. Lubricate new filter gasket with hydraulic oil.
4. Ensure that the filter mounting area is clean. Screw
filter on until gasket contacts mounting plate. Then
tighten filter 1/2 turn.
5. Start engine and let run for about two minutes to purge
air from the system. Stop the engine and check for
leaks. Check fluid level and replenish if necessary.
Changing the Rear Axle
Lubricant
Note: This procedure is for model 03544 only.
After every 800 hours of operation the oil in the rear axle
must be changed.
1. Position machine on a level surface.
2. Clean area around the drain plugs (Fig. 68).
3. Remove plug allowing oil to drain into drain pans.
4. After oil is drained, apply thread locking compound on
drain plug threads and reinstall in axle.
5. Fill axle with lubricant; refer to Checking the Rear Axle
Lubricant, page 22.

Adjusting Rear Wheel Toe-In
The rear wheels should have 0 to 1/8 in. toe-in when they
are pointed straight ahead. To check toe-in, measure the
center-to-center distance, at axle height, in front and rear of
steering tires. If toe-in is not within specifications, an
adjustment is required. After every 800 operating hours or
annually, check rear wheel toe-in.
Models 03540 and 03543
1. Rotate the steering wheel so the rear wheels are straight
ahead.
2. Loosen the jam nuts on both tie rods (Fig. 69). Adjust
both tie rods equally until center-to-center distance at
front of rear wheels is 0–1/8 in. (0–3 mm) less than at
the rear of the wheels.
