Adjusting the Lift Cylinders
To regulate the height of the front-cutting units when in
the raised (transport) position, you can adjust the front-lift
cylinders.
1. Lower the cutting units to the ground.
2. Loosen the jam nut on the clevis of the cutting-unit-lift
cylinder that needs to be adjusted.
3. Disconnect the cylinder clevis from the lift arm.
4. Rotate the clevis until you attain the desired height.
5. Connect the cylinder clevis to the lift arm and tighten
the jam nut.

Changing the Hydraulic Fluid
and Filter
Service Interval: After the first 50 hours—Change the
hydraulic filter.
Every 800 hours—Change the hydraulic fluid.
Every 800 hours—Change the hydraulic filter.
If the oil becomes contaminated, have your Toro distributor
flush the system. Contaminated oil looks milky or black when
compared to clean oil.
1. Clean the area around the filter mounting area
59). Place a drain pan under the filter and remove the
filter.
1. Hydraulic filter
Note: If the oil is not going to be drained, disconnect
and plug the hydraulic line going to the filter.
2. Fill the replacement filter with the appropriate hydraulic
fluid, lubricate the sealing gasket, and hand turn it until
the gasket contacts the filter head. Then tighten it 3/4
turn further.
3. Fill the hydraulic reservoir and small-auxiliary tank with
approximately 32 L (8-1/2 US gallons) of hydraulic
fluid; refer to
Checking the Hydraulic-Fluid Level (page
22).
4. Start the machine and run it at idle for 3 to 5 minutes
to circulate the fluid and remove any air trapped in the
system. Shut off the engine and check the fluid level.
5. Dispose of the oil and filter properly.
Note: If the leak-detector alarm sounds, turn the key
off and wait a few minutes for the oil level to equalize in
the tanks. Check the fluid level and add oil, if required.
