multi-viscosity hydraulic fluids which allows operation at
lower temperatures without the increased viscosity, which
is associated with straight viscosity fluids.
Note: When changing from one type of hydraulic fluid to
the other, be certain to remove all the old fluid from the
system, because some brands of one type are not
completely compatible with some brands of the other type
of hydraulic fluid.
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 l) of hydraulic oil. Order
part no. 44–2500 from your authorized Toro distributor.
Not recommended for biodegradable fluid (use food
coloring).
1. Position the machine on a level surface.
2. Check the fluid level by viewing it in the sight gauge
(Fig. 27). If the fluid is cold, the level should be at the
bottom of the gauge. If the fluid is hot, the level should
be at the center of the gauge.

3. If the fluid level is not at least at the bottom of the
gauge when it is cold, remove the cap from the
hydraulic fluid reservoir (Fig. 27) and slowly fill the
reservoir with high quality hydraulic fluid until the level
in it reaches the bottom of the sight gauge. Do not
overfill.
Important To prevent system contamination, clean the
top of the hydraulic fluid containers before puncturing.
Ensure that the pour spout and funnel are clean.
4. Install the reservoir cap. Wipe up any fluid that may
have spilled.
Checking the Tire Pressure
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 16–20 psi (110–138 kPa).
Important Maintain the recommended pressure in all
tires to ensure a good quality-of-cut and proper machine
performance. Do not under-inflate.
Checking the Reel to Bedknife
Contact
Each day before operating, check the reel to bedknife
contact, regardless if the quality of cut had previously been
acceptable. There must be light contact across the full
length of the reel and bedknife; refer to Adjusting the Reel
to the Bedknife in the Cutting Unit Operator’s Manual.
Checking the Torque of the
Wheel Nuts
Failure to maintain proper torque of the wheel
nuts could result in personal injury.
Torque the wheel nuts to 45–65 ft.-lb. (61–88 Nm)
after 1–4 hours of operation and again after 10
hours of operation. Torque every 200 hours
thereafter.
