Belt Maintenance
Check the condition and tension of the alternator belt after
the first day of operation and every 100 operating hours
thereafter.
Tensioning the Alternator Belt
1.
Open the hood.
2.
Check the tension of the alternator belt by depressing
it, with moderate thumb pressure, midway between the
alternator and the engine pulley (Figure 61).

Alternator belt
The belt should deflect 7 to 9 mm (0.28 to 0.35 inch).
If the deflection is incorrect, proceed to step 3. If
correct, continue operation.
3.
Loosen the bolt securing the brace to the engine
(Figure 61), the bolt securing the alternator to the brace
and the pivot bolt.
4.
Insert a pry bar between the alternator and the engine
and pry out on the alternator.
5.
When you achieve the proper tension, tighten
the alternator, brace and pivot bolts to secure the
adjustment.
Hydraulic System
Maintenance
Changing the Hydraulic Fluid
Change hydraulic fluid after every 800 operating hours, in
normal conditions. If 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.
Stop the engine and raise the hood.
2.
Place a large drain pan under the fitting secured to the
bottom of the hydraulic fluid reservoir (Figure 62).

1.
Hose
3.
Disconnect the hose from the bottom of the fitting and
let the hydraulic fluid flow into the drain pan.
4.
Install the hose when hydraulic fluid stops draining.
5.
Fill the reservoir with approximately 30 liters (8 U.S.
gallons) of hydraulic fluid; refer to Checking the
Hydraulic Fluid.
Important:
Use only hydraulic fluids specified.
Other fluids could cause system damage.
6.
Install the reservoir cap.
7.
Start the engine and use all of the hydraulic controls to
distribute hydraulic fluid throughout the system. Also
check for leaks.
8.
Stop the engine.
9.
Check the level of the hydraulic fluid and add enough
to raise level to the Full mark on the dipstick.
Important:
Do not over-fill.
