Hitching to Tractor (continued)
Clean hydraulic hose couplers before connecting to the tractor. For convenience, it is recom-
mended to connect the fl ow door circuit hoses to tractor implement coupler #1, auger spout
circuit hoses to coupler #2, and attach auger fold circuit to coupler #3.
This unit is equipped with color bands attached to the hydraulic hoses. This will help in
identifying the hose function and correct hook up.
Green: Raise and Lower Auger
Red: Flow Door Open and Close
Yellow: Spout In and Out
After initial set-up or replacement of any hydraulic component on the cart, air must be re-
moved from the cart’s hydraulic system.
Route hoses away from areas that may cause abrasion or kinking of hoses during operation.
Before disconnecting hoses from the tractor, relieve pressure in the system. See the tractor’s
Operator’s Manual for the proper procedure. Shut off engine and apply parking brake before
disconnecting hoses. Install couplers into storage slots provided.
Hydraulic Connections for Hydraulic Drive
It is possible that the tractor utilizes more than one pump to achieve higher hydraulic fl ow rates.
To maximize hydraulic fl ow to auger hydraulic drive motor, refer to tractor’s Operator’s Manual to
determine which couplers should be used to achieve maximum fl ow. A fl ow test by your dealer’s
tractor technician can be performed and is recommended to assure maximum fl ow without
exceeding motor limits.
A case drain hose is supplied with the 100 gpm kit and can be used.
• The case drain line is to be connected to the tractor’s low pressure return line ONLY! DO
NOT connect to the hydraulic couplers! DO NOT plumb both case drain and hydraulic drive
return lines to low pressure return. Pressure in return lines will back flow into case drain and
shorten motor life.
To avoid thermal shock, maintain a temperature difference less than 50 degrees between
the tractor’s hydraulic fl uid and the motor’s hydraulic fl uid. With the fl ow door closed, run
the motor in very short intervals (bursts with 15 second pauses) or low hydraulic fl ow rate
at startup, in order for hydraulic oil to slowly exchange colder oil in the motor with warmer
oil from the tractor. Particularly advised on cold days and/or fi rst loads of the day.
