Replace Hydraulic Oil Filter
Initially, change filter after the first 50 operating hours,
thereafter, every 800 operating hours, annually, or on in-
dication. Use Toro replacement filter (Part No.
86–6110).
IMPORTANT: Use of any other filter may void the
warranty on some components.
1. Remove seat lock pin, raise seat and hold open with
support rod. Also remove front panel (secured with mag-
nets) ahead of the seat.
2. Clean area around filter mounting area (Fig. 93).
Place drain pan under filter and remove filter.
3. Lubricate new filter gasket and fill the filter with hy-
draulic oil.
4. Assure filter mounting area is clean. Screw filter on
until gasket contacts mounting plate. Then tighten filter
one–half turn.
5. Start engine and let run for about two minutes to
purge air from the system. Stop the engine and check for
leaks.
6. Check hydraulic oil level (see Check Hydraulic Sys-
tem Fluid).

NOTE: Under certain conditions, a bypass valve in the
filter mounting plate allows oil to bypass the filter. Before
the filter starts to bypass a warning light on the steering
console will illuminate. The warning light may come on
momentarily when the oil is cold. If the light does not go
out after the oil is warm, the filter is clogged or an electri-
cal problem exists. Correct problem before commenc-
ing operation.

ating hours, or annually, whichever comes first. More
often in extremely dusty or dirty conditions.

wrench. Install new breather (Fig. 94).
