Belt Maintenance
Servicing the Alternator Belt
Service Interval: Every 100 hours
Check the condition and tension of the belts (Figure 54)
after every 100 operating hours.
1. Proper tension will allow 3/8 in. (10 mm) deflection
when a force of 10 lb. is applied on the belt midway
between the pulleys.
2. If the deflection is not 3/8 in. (10 mm), loosen
the alternator mounting bolts (Figure 54). Increase
or decrease the alternator belt tension and tighten
the bolts. Check the deflection of the belt again to
ensure that the tension is correct.

Hydraulic System
Maintenance
Changing the Hydraulic Fluid
Service Interval: Every 800 hours
Change the hydraulic fluid after every 800 operating
hours, in normal conditions. If the fluid becomes
contaminated, contact your local Toro distributor
because the system must be flushed. Contaminated fluid
looks milky or black when compared to clean oil.
1. Turn the engine off and raise the hood.
2. Disconnect the case return line from the bottom of
the reservoir and let the hydraulic fluid flow into a
large drain pan. Connect the line when the hydraulic
fluid stops draining.
3. Fill the reservoir with approximately 7.5 gallons of
hydraulic fluid; refer to Checking the Hydraulic Fluid.
Important: Use only the hydraulic fluids
specified. Other fluids could cause system
damage.
4. Install the reservoir cap. Start the engine and use all
of the hydraulic controls to distribute hydraulic fluid
throughout the system. Also check for leaks; then
stop the engine.
5. Check the fluid level and add enough to raise level
the level to the FULL mark on the dipstick. Do not
overfill.
Replacing the Hydraulic Filters
Service Interval: After the first 200 hours
Every 800 hours
Change the 2 hydraulic filters initially after the first 200
operating hours. Thereafter, change the filters after
every 800 operating hours, in normal conditions.
Use Toro replacement filters Part No. 94-2621 for the
rear (cutting unit) of the machine and 75-1310 for the
front (charge) of the machine.
Important: Use of any other filter may void the
warranty on some components.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, engage the parking
brakes, and remove the ignition key.
2. Clean the area around the filter mounting area. Place
a drain pan under the filter and remove the filter
(Figure 55 and Figure 56).
