Pour point, ASTM D97
FZG, fail stage
Water content (new fluid)
Industry Specifications:
Vickers I-286-S, Vickers M-2950-S, Denison HF-0,
Vickers 35 VQ 25 (Eaton ATS373-C)
The proper hydraulic fluids must be specified for
mobile machinery (as opposed to industrial plant usage),
multiweight-type, with ZnDTP or ZDDP anti-wear additive
package (not an ashless-type fluid).
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 fl oz)
bottles. One bottle is sufficient for 15 to 22 liters (4 to 6
US gallons) of hydraulic oil. Order part 44-2500 from
your Authorized Toro Distributor.
Synthetic, Biodegradable Hydraulic Fluid
(available in 19 liter (5 gallon) containers or 208 liter (55
gallon) drums—see the parts documentation or your Toro
distributor for part numbers)
This high-quality, synthetic, biodegradable fluid has been
tested and found compatible for this Toro model. Other
brands of synthetic fluid may have seal compatibility problems
and Toro cannot assume responsibility for unauthorized
substitutions.
Note: This synthetic fluid is not compatible with the
Toro Biodegradable Fluid previously sold. See your Toro
Distributor for more information.

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
1. Hydraulic tank cap
-36.7°C to -45°C (-34°F to
-49°F)
11 or better
500 ppm (maximum)
29). 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 6 mm (1/4 inch) of the mark 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 Reel-to-Bedknife
Contact
Each day before operating, check the reel-to-bedknife contact,
regardless of whether the quality of cut had previously been
acceptable. There must be light contact across the full length
of the reel and the bedknife (refer to Adjusting the Reel to
Bedknife in the cutting unit Operator's Manual).
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 83 kPa (12 psi).
Note: Maintain the recommended pressure in all tires to
ensure a good quality of cut and proper machine performance.
DANGER
Low tire pressure decreases machine side hill
stability. This could cause a rollover, which may
result in personal injury or death.
Do not under-inflate the tires.
Torquing the Wheel Nuts
Service Interval: After the first hour
After the first 10 hours
Every 200 hours
Torque the wheel nuts to 61 to 88 N-m (45 to 65 ft-lb).
WARNING
Failure to maintain proper torque of the wheel nuts
could result in personal injury.
Maintain proper torque of the wheel nuts.
Positioning the Seat
Changing the Seat Position
The seat can move forward and backward. Position the seat
where you have the best control of the machine and are most
comfortable
