Hydraulic System

Hydraulic Fluid Specifications
The reservoir is filled at the factory with high-quality
hydraulic fluid. Check the level of the hydraulic fluid
before you first start the engine and daily thereafter;
refer to Checking the High-Flow Hydraulic-Fluid Level
(page 60).
Recommended replacement fluid: Toro 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 fluid requires less frequent fluid and filter
changes.
Alternative fluids: If Toro PX Extended Life
Hydraulic Fluid is not available, you may use another
conventional, petroleum-based hydraulic fluid having
specifications that fall within the listed range for all the
following material properties and that it meets industry
standards. Do not use synthetic fluid. Consult with
your lubricant distributor to identify a satisfactory
product.
Note:
Toro does not assume responsibility for
damage caused by improper substitutions, so use
products only from reputable manufacturers who will
stand behind their recommendation.
High Viscosity Index/Low Pour Point
Anti-wear Hydraulic Fluid, ISO VG 46
Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM D2270
Pour Point, ASTM D97
Industry Specifications:
Note:
Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic fluid is available in 20 ml (0.67 fl oz)
bottles. A bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic fluid. Order Part No. 44-2500
from your authorized Toro distributor.

Checking the High-Flow
Hydraulic-Fluid Level
TC Models Only
Service Interval: Before each use or daily—Check
the high-flow hydraulic-fluid level
(TC models only). (Check the level
of hydraulic fluid before the engine
is first started, and daily thereafter)
1. Park the machine on a level surface.
2. Engage the parking brake.
3. Shut off the engine and remove the key.
4. Clean the area around the filler neck and the
cap of the hydraulic tank
5. Remove the cap from the filler neck.
1. Cap
6. Remove the dipstick
neck and wipe it with a clean rag.
7. Insert the dipstick into the filler neck, then
remove it and check the fluid level.
Note:
The fluid level should be between the 2
marks on the dipstick.
8. If the level is low, add the appropriate fluid
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 filler 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-flow hydraulics.
11. Shut off the engine and attachment and check
for leaks.
