CART WITH THE AUGER OR TRAC-
TOR RUNNING. SERIOUS OR DEATH CAN
OCCUR DUE TO ENTANGLEMENT WITH
ROTATING COMPONENTS. ALWAYS STOP
ENGINE AND REMOVE KEY BEFORE EN-
TERING CART.
The optional hydraulically-driven auger permits
cart operation using tractors that are not
equipped with a PTO. However, due to the
power requirements of a grain cart, it should
be expected that a hydraulically-driven grain
cart will not unload as quickly as a PTO
driven cart.
IMPORTANT: The hydraulic motor has an
intermittent rating of 55 gpm hydraulic fl ow at
3000 psi. Sustained fl ow and pressure above
these amounts will dramatically reduce motor
life. Be aware of maximum tractor hydraulic
fl ow and pressure before operating auger.
1. Before loading cart or operating au-
ger, verify that the fl ow control door is
closed.
2. Choose an area free from obstructions
and fully unfold auger to the unloading
position.

3. Connect hydraulic hoses to two tractor
hydraulic circuits. Attach pump pressure
hoses to
RETRACT
ports on tractor. If
available, the return hoses may be plumbed
to a low-pressure return port on the trac-
tor.
The dual connections help utilize full tractor
hydraulic power at the cart hydraulic motor.
For tractors that have more than 55 gpm
available pump output, use tractor fl ow con-
trols to regulate total output to a maximum
of 55 gpm.
4.
Engage both auger hydraulic circuits at low
engine RPM, then increase engine to full
throttle.
5. While watching hydraulic pressure gauge,
begin slowly opening fl
ow control door.
Stop opening fl ow control door when pres-
sure (on hydraulic gauge by pump) climbs
to within 200 psi less than maximum tractor
hydraulic pressure.
IMPORTANT: If auger stalls during unloading,
immediately place tractor hydraulic controls for
motor functions in FLOAT to stop auger. Close
fl ow control door, then move all hydraulic con-
trols to HOLD. Relieve auger grain pressure by
opening auger cleanout door to remove some
grain before attempting to restart auger.
6.
To slow or stop grain fl ow, close fl ow door
rather than reducing tractor RPM.
Close
fl ow door fully when unloading is com-
plete.
7.
Stop auger by placing both auger hydraulic
circuits in
FLOAT
. This reduces strain on
driveline components and prolongs hydraulic
motor life. Move controls to
HOLD
after
auger has come to a complete stop.
8. Choose an area free from obstructions and
fully fold auger to the transport position.
