Tire Pressure; Checking The Torque Of The Wheel Nuts - Toro Greensmaster
3150 Operator's Manual

Mobil. Contact your Toro Distributor for details. The oil is
available in 5 gallon (19 l) containers from your Toro
Distributor, order part no. 100–7674.
Note: Use of this fluid requires installation of an Oil Cooler
Kit, Part No. 105–8339, to the traction unit. This
biodegradable fluid will break down quickly if the
temperature exceeds 180°F (82°C).
Premium Biodegradable Hydraulic Fluid—Mobil EAL
EnviroSyn 46H
Important Mobil EAL EnviroSyn 46H is the only
synthetic biodegradable fluid approved by Toro. This fluid
is compatible with the elastomers used in Toro 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 5
gallon (19 l) containers or 55 gallon drums from your
Mobil Distributor.
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.
This red dye is not recommended for use with
biodegradable fluids. Use food coloring.
Important Regardless of the hydraulic fluid type used,
any traction unit used for off green applications,
verticutting or used during ambient temperatures above
85°F (29°C) should have Oil Cooler Kit, Part No.
105–8339, installed.
Filling the Hydraulic Tank
1. Position the machine on a level surface. Make sure the
machine has cooled down so the oil is cold. Check the
oil level by viewing the sight gauge on the side of the
auxiliary oil tank (Fig. 16). If the oil level is up to the
Full mark next to the gauge, the oil level is sufficient.
2. If the oil level is below the Full mark on the auxiliary
tank, remove the cap from the hydraulic oil tank and
slowly fill the tank with the appropriate high quality
hydraulic fluid until the level is up to the mark next to
the sight gauge. Do not mix oils. Install the cap.
Important To prevent system contamination, clean the
top of the hydraulic oil containers before puncturing them.
Ensure that the pour spout and funnel are clean.
Note: Make a close visual inspection of the hydraulic
components. Inspect them for leaks, loose fasteners,
missing parts, improperly routed lines, etc. Make any
corrections necessary.

Tire Pressure

The tires are over-inflated at the factory for shipping
purposes. Reduce the pressure to the proper levels before
starting the unit.
Vary the tire pressure for the front wheels, depending upon
your turf conditions, from a minimum of 8 psi to a
maximum of 12 psi (55 to 83 kPa).
Vary the tire pressure for the rear wheel from a minimum of
8 psi to a maximum of 15 psi (55 to 103 kPa).
Checking the Torque of the
Wheel Nuts
Warning
Failure to maintain proper torque of the wheel
nuts could result in personal injury.
Torque the wheel nuts to 70–90 ft.-lb. (95–122 NVm)
after 1–4 hours of operation and again after 10
hours of operation. Torque every 200 hours
thereafter.
