High Viscosity Index/Low Pour Point Anti-wear
Hydraulic Fluid, ISO VG 46 (cont'd.)
Viscosity Index ASTM D2270
Pour Point, ASTM D97
Industry Specifications:
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 gallons (15-22
1) of hydraulic oil. Order part no. 44-2500 from your
authorized Toro distributor.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, and remove the key.
2. Unlatch the seat, raise it, and engage the prop rod.
3. Clean the area around the filler neck and cap of the
hydraulic tank (Figure 12). Remove the cap from
the filler neck.

4. Remove the dipstick from the filler neck and wipe
it with a clean rag. Insert the dipstick into the filler
neck; then remove it and check the fluid level. The
fluid level should be between the two marks on the
dipstick.
5. If the level is low, add the appropriate fluid to raise
the level to the upper mark.
6. Install the dipstick and cap onto the filler neck.

Checking the Planetary Gear Drive Oil
Service Interval: Every 400 hours
Check the oil level after every 400 hours of operation
or if external leakage is noted. Use high quality SAE
85W-140 gear lube as a replacement.
The capacity of the system is approximately 16 oz (0.5 l).
1. With the machine on a level surface, position the
wheel so that the check/drain plug (Figure 13) is at
either the 3 or 9 o'clock position.

1. Check/drain plug
2. Add gear oil to the hole in the planetary, if necessary,
to bring the oil up to the proper level. Install the
plug.
3. Repeat the procedure on the opposite gear assembly.
Checking the Rear Axle Lubricant
Service Interval: Every 400 hours
The rear axle is filled with SAE 85W-140 gear lube.
Check the oil level before the engine is first started and
every 400 hours thereafter. The capacity is 80 oz (2.4 l).
Visually inspect for leaks daily.
1. Position the machine on a level surface.
2. Remove a check plug from one end of the axle
(Figure 14) and make sure that the lubricant is up to
the bottom of the hole. If the level is low, remove
the fill plug (Figure 14) and add enough lubricant to
bring the level up to the bottom of the check plug
holes.
