Note: Many hydraulic fluids are almost colorless, making it
difficult to spot leaks. A red dye additive for the hydraulic
system oil is available in 2/3 oz. (20 ml) bottles. One bottle
is sufficient for 4–6 gal (15–22 1) of hydraulic oil. Order
part no.44–2500 from your authorized Toro distributor.
1. Position machine on a level surface, raise the
implement, and stop the engine.
2. Unscrew dipstick cap (Fig. 24) from the filler neck and
wipe it with a clean rag. Screw dipstick cap finger tight
onto filler neck. Unscrew the dipstick and check level
of fluid. If level is not within 1/2 in. (13 mm) from the
groove in the dipstick (Fig. 24), add enough fluid to
raise level to groove mark. Do not overfill by more
than 1/2 in. (13 mm) above groove.
Important
When adding oil to the hydraulic system,
use a funnel with a fine wire screen—200 mesh—and
ensure funnel and oil are immaculately clean. This
procedure prevents accidental contamination of the
hydraulic system.

Checking the Rear Axle

The rear axle has three separate reservoirs which use SAE
80W-90 wt. gear lube. Although the axle is shipped with
lubricant from the factory, check the level before operating
the machine.
1. Position the machine on a level surface.
2. Remove check plugs from axle and make sure lubricant
is up to bottom of each hole. If level is low, remove fill
plugs and add enough lubricant to bring the level up to
the bottom of the check plug holes (Fig. 25).
