Adjusting the Controls
The factory adjusts the controls before shipping the machine.
However, after many hours of use, you may need to adjust
the traction control alignment, the N
EUTRAL
position of the
traction control, and the tracking of the traction control in the
full forward position.
Contact your Authorized Service Distributor to adjust the
controls of your machine.

Hydraulic Fluid
Specifications
Use only 1 of the following fluids in the hydraulic system:
•
Toro Premium Transmission/Hydraulic Tractor
Fluid
(refer to your Authorized Toro Dealer for more
information)
•
Toro Premium All Season Hydraulic Fluid
(refer to
your Authorized Toro Dealer for more information)
•
If either of the above Toro fluids are not available,
you may use another
Universal Tractor Hydraulic
Fluid (UTHF
), but they must be only
conventional,
petrolium-based
products. The specifications must
fall within the listed range for all the following material
properties and the fluid should meet the listed industry
standards. Check with your hydraulic fluid supplier to
determine if the fluid meets these specifications.
Note:
Toro 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 fluids are almost colorless, making
it difficult to spot leaks. A red dye additive for the
hydraulic system fluid is available in 20 ml (2/3 fl oz)
bottles. One bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic fluid. Order Part No. 44-2500 from
