Hydraulic System
Maintenance
Hydraulic System Safety
• Seek immediate medical attention if uid is injected
into skin. Injected uid must be surgically removed
within a few hours by a doctor .
• Ensure that all hydraulic-uid hoses and lines are
in good condition and all hydraulic connections
and ttings 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
uid.
• Use cardboard or paper to nd hydraulic leaks.
• Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
Hydraulic Fluid
Specications
Every 1,500 hours/Every 2 years (whichever
comes rst)
Hydraulic T ank Capacity: 23 L (6 US gallons)
Use only 1 of the following uids in the hydraulic
system:
• T oro Premium T ransmission/Hydraulic T ractor
Fluid (refer to your Authorized Service Dealer for
more information)
• T oro Premium All Season Hydraulic Fluid
(refer to your Authorized Service Dealer for more
information)
• If either of the above T oro uids are not available,
you may use another Universal T ractor
Hydraulic Fluid (UTHF ), but they must be only
conventional, petroleum-based products. The
specications must fall within the listed range for
all the following material properties and the uid
should meet the listed industry standards. Check
with your hydraulic uid supplier to determine if the
uid meets these specications.
Note: T oro will not assume responsibility for
damage caused by improper substitutions, so use
only products from reputable manufacturers who
will stand behind their recommendations.

Note: Many hydraulic uids are almost colorless,
making it dif cult to spot leaks. A red dye additive
for the hydraulic system uid is available in 20 ml
(0.67  oz) bottles. One bottle is suf cient for 15 to
22 L (4 to 6 US gallons) of hydraulic uid. Order
Part No. 44-2500 from your Authorized Service
Dealer .
Checking the
Hydraulic-Fluid Level
Service Interval : Every 25 hours
Refer to Hydraulic Fluid Specications ( page 37 ) .
1. Park the machine on a level surface, engage
the parking brake (if applicable), and lower the
grinder .
2. Shut of f the engine and remove the key .
3. Look into the glass bubble on the right side of
the machine. If you cannot see hydraulic uid in
the bubble, continue this procedure to add uid.

4. Remove the cover plate; refer to Removing the
Cover Plate ( page 21 ) .
5. Clean the area around the ller neck of the
