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 9). 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).
