Checking The Hydraulic Fluid; Checking The Planetary Gear Drive Oil - Toro 30410 Operator's Manual

Checking the Hydraulic Fluid

The machines reservoir is filled at the factory with
approximately 8 gallons of high quality hydraulic fluid.
Check the level of hydraulic fluid before the engine is
first started and daily thereafter. Appropriate hydraulic
oils are listed below.
The following list is not assumed to be all–inclusive.
Hydraulic fluids produced by other manufacturers may be
used if they can cross reference to find an equivalent to the
products listed. Toro will not assume responsibility for
damage caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.

Important
The ISO VG 46 Multigrade fluid has been
found to offer optimal performance in a wide range of
temperature conditions. For operation in consistently high
ambient temperatures, 65 F (18 C) to 120 F (49 C), ISO
VG 68 hydraulic fluid may offer improved performance.
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. Not
recommended for biodegradable fluid (use food coloring).
Biodegradable Hydraulic Fluid – Mobil 224H
Important Mobil EAL 224H is the only biodegradable
oil tested and approved by Toro. 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 published by

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.

Checking the Planetary Gear
Drive Oil
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
so that the check/drain plug (Fig. 6) is at either the 2 or
10 o'clock position.
