Checking The Planetary Gear Drive Oil - Toro 30411 Operator's Manual

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.
Biodegradable Hydraulic Fluid – Mobil 224H
Toro Biodegradable Hydraulic Fluid
(Available in 5 gallon pails or 55 gallon drums. See
parts catalog or Toro distributor for part numbers.)
Alternate fluid: Mobil EAL 224H
This is vegetable–oil based biodegradable oil tested and
approved by Toro for this model. This fluid is not as
resistant to 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.
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 (Fig. 5). 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.

Check the oil level after every 400 hours of operation or if
external leakage is noted. Use high quality SAE
85W-140 wt. 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
