Preparing the Tow Vehicle
No Parts Required
Procedure
1.
Verify your tow vehicle meets the specifications
listed in the table in
2.
Determine whether your machine has an open
or closed hydraulic system.
Important:
Special operating precautions
must be taken if your machine has a
closed hydraulic system. See Operating
Instructions.
Note:
Contact your tow vehicle's Authorized
Service Dealer for proper installation of the
remote hydraulics because damage may occur
to the system if it is improperly installed.
3.
Ensure that the tow vehicle's hydraulic system
will couple to the remote hydraulic supply/return
lines of the transport frame control valve. Quick
disconnect couplers are included with the
transport frame, but different sized hydraulic
quick coupler tips may be substituted to match
the existing machine couplers.
4.
The hydraulic system of the transport frame is
filled at the factory with high-quality hydraulic
fluid. Check the level of the hydraulic fluid in the
tow vehicle before the engine is first started and
daily thereafter. Before operating the transport
frame, make sure the hydraulic fluid is suitable
for use with the tow vehicle hydraulic system.
The recommended replacement fluid is as
follows:
Recommended replacement fluid: Toro
Premium Transmission/Hydraulic Tractor Fluid;
available in 19 L (5 US gallon) pails or 208 L (55
US gallon) drums.
Alternative fluids: If Toro Premium Tractor Fluid
is not available, you may use other conventional,
petroleum-based Universal Tractor Hydraulic
Fluids (UTHF), provided that its specifications
fall within the listed range for all the following
material properties and that it meets industry
standards. We do not recommend the use
of 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.
Material Properties:
Viscosity, ASTM D445

Pour Point, ASTM D97
Industry Specifications:

FNHA-2-C-201.00, Kubota UDT, John Deere J20C,
Vickers 35VQ25, and Volvo WB-101/BM
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 (⅔ fl oz) bottles. A bottle is sufficient for
15 to 30 L (4 to 8 US gallons) of hydraulic fluid.
Order Part No. 44-2500 from your authorized
Toro distributor.
5.
Adjust the tow vehicle seat to a comfortable
operating position.
6.
Adjust the drawbar (hitch) position of the tow
vehicle so that the mounting hole is less than
125 cm (50 inches) from the outside of the rear
tow vehicle tire
interference with the front cutting unit lift arms.
Refer to the Operator's Manual for your tow
vehicle for the drawbar adjustment procedure.
Note:
If the tow vehicle drawbar hitch cannot
be adjusted as described above, use caution
when turning to avoid contact.
