Hydraulic Fluid Specications
The reservoir is lled at the factory with high-quality
hydraulic uid. Check the level of the hydraulic uid
before you rst start the engine and daily thereafter;
refer to Checking the High-Flow Hydraulic-Fluid Level
( page 60 ) .
Recommended replacement uid: T oro PX
Extended Life Hydraulic Fluid; available in 19 L (5 US
gallon) pails or 208 L (55 US gallon) drums.
Note: A machine using the recommended
replacement uid requires less frequent uid and lter
changes.
Alternative uids: If T oro PX Extended Life
Hydraulic Fluid is not available, you may use another
conventional, petroleum-based hydraulic uid having
specications that fall within the listed range for all the
following material properties and that it meets industry
standards. Do not use synthetic uid. Consult with
your lubricant distributor to identify a satisfactory
product.
Note: T oro does not assume responsibility for
damage caused by improper substitutions, so use
products only from reputable manufacturers who will
stand behind their recommendation.
High V iscosity Index/Low Pour Point
Anti-wear Hydraulic Fluid, ISO VG 46
Material Properties:
V iscosity , ASTM D445 cSt @ 40°C (104°F)
44 to 48
V iscosity Index ASTM D2270
140 or higher
Pour Point, ASTM D97 -37°C to -45°C (-34°F
to -49°F)
Industry Specications: Eaton V ickers 694 (I-286-S,
M-2950-S/35VQ25 or
M-2952-S)
Note: Many hydraulic uids are almost colorless,
making it dif cult to spot leaks. A red dye additive for
the hydraulic uid is available in 20 ml (0.67  oz)
bottles. A 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 T oro distributor .
Checking the High-Flow
Hydraulic-Fluid Level
TC Models Only
Service Interval : Before each use or daily —Check
the high-ow hydraulic-uid level
(TC models only). (Check the level
of hydraulic uid before the engine
is rst started, and daily thereafter)
1. Park the machine on a level surface.
2. Engage the parking brake.
3. Shut of f the engine and remove the key .
4. Clean the area around the ller neck and the
cap of the hydraulic tank ( Figure 70 ).
5. Remove the cap from the ller neck.

1. Cap
6. Remove the dipstick ( Figure 70 ) from the ller
neck and wipe it with a clean rag.
7. Insert the dipstick into the ller neck, then
remove it and check the uid level.
Note: The uid level should be between the 2
marks on the dipstick.
8. If the level is low , add the appropriate uid
to raise the level to the upper mark; refer to
Changing the High-Flow Hydraulic Fluid and
Filter ( page 61 ) .
9. Install the dipstick and cap onto the ller neck.
10. Start the engine and turn on the attachment.
Note: Let them run for about 2 minutes to purge
air from the system.
Important: The machine must be running
before starting the high-ow hydraulics.
1 1. Shut of f the engine and attachment and check
for leaks.
