Checking the Hydraulic
System
Service Interval: Before each use or daily—Check the
hydraulic fluid level.
The machines reservoir is filled at the factory with
approximately 6 U.S. gallons (22.7 l) of high quality hydraulic
fluid. Check the level of the hydraulic fluid before
the engine is first started and daily thereafter. The
recommended replacement fluid is Toro Premium All
Season Hydraulic Fluid (Available in 5 gallon pails or 55
gallon drums. See parts catalog or Toro distributor for part
numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. Toro does
not recommend the use of synthetic fluid. Consult with your
lubricant distributor to identify a satisfactory product Note:
Toro will not assume responsibility for damage caused by
improper substitutions, so use only products from reputable
manufacturers who will stand behind their recommendation.

hydraulic systems and is suitable for a wide-range
of temperature conditions. This fluid is compatible
with conventional mineral oils, but for maximum
biodegradability and performance the hydraulic system
should be thoroughly flushed of conventional fluid. The
oil is available in 19 liters (5 gallon) containers or 55
gallon drums from your Mobil Distributor.
Important: Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive
for the hydraulic system oil is available in 20 ml (2/3
oz.) bottles. One bottle is sufficient for 15-22 liters (4-6
gallons) 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, and stop the engine.
2. Clean the area around the filler neck and cap of the
hydraulic tank (Figure 30). Remove the cap.

3. 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 within the marks on the dipstick.
4. If the level is low, add the appropriate fluid to raise the
level to the full mark.
5. Install the dipstick and cap onto the filler neck.
Checking the Tire Pressure
Service Interval: Before each use or daily
The tires are over-inflated for shipping. Therefore, release
some of the air to reduce the pressure. The correct air
pressure in the tires is 97 to 124 kPa (14 to 18 psi).
Note: Maintain the recommended pressure in all tires to
ensure a good quality of cut and proper machine performance.
