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.
Biodegradable Hydraulic Fluid - Mobil EAL 224H
Toro Biodegradable Hydraulic Fluid
5 gallon pails or 55 gallon drums. See parts catalog or
Toro distributor for part numbers.)
* Use only when temperatures are above 30° F.
This is vegetable-oil based biodegradable oil tested and
approved by Toro for this model. This fluid is not as
resistant to high temperatures as standard fluid, so
install an oil cooler if required by the operator manual
and follow recommended fluid change intervals with
this fluid. Contamination by mineral-based hydraulic
fluids will change the biodegradability and toxicity of
this oil. When changing from standard fluid to the
biodegradable type, be certain to follow the approved
flushing procedure. Contact your local Toro Distributor
for details.

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 10) is at
either the 2 or 10 o'clock position.
