Hydraulic System
Maintenance

Hydraulic System Safety

•
Ensure that all hydraulic-fluid hoses and lines are in
good condition and all hydraulic connections and
fittings are tight before applying pressure to the
hydraulic system.
•
Keep your body and hands away from pinhole leaks
or nozzles that eject high-pressure hydraulic fluid.
•
Use cardboard or paper to find hydraulic leaks.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic system.
•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.

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 fluid.
1. Park the machine on a level surface, lower the cutting
units, engage the parking brake, shut off the engine,
and remove the key.
2. Raise the hood.
3. Disconnect the case return line from the bottom of the
reservoir and let the hydraulic fluid flow into a large
drain pan.
4. Connect the line when the hydraulic fluid stops
draining.
5. Fill the reservoir with approximately 28.4 L (7.5 US
gallons) of hydraulic fluid; refer to
of the Hydraulic Fluid (page
Important: Use only the 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.
8. Check for leaks and shut off the engine.
9. Check the fluid level and add enough to raise the level
to the Full mark on the dipstick.
Note: Do not overfill the hydraulic system.

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. Park the machine on a level surface, lower the cutting
units, engage the parking brake, shut off the engine,
and remove the key.
2. Clean the area around the filter mounting area.
3. Place a drain pan under the filter and remove the filter
(Figure 79 and Figure
4. Lubricate the new filter gasket and fill the filter with
hydraulic fluid.
