HYDRAULIC AUGER OPERATION
For PTO & DIRECT DRIVE Applications
250946
1. Initial start-up: Flow Door is to be closed.
2. With flow door closed, engage hydraulic motor with maximum oil flow from
tractor. NOTE: Free running auger oil pressure will range 500 PSI or less.
3. The pressure gauge will register system work load as flow door is opened.
Slowly open flow door to #1 setting on auger tube decal gauge. While
monitoring the auger discharge rate and hydraulic pressure, gradually increase
flow door opening to approximately 2 - 2 1/2 setting. Watch the pressure gauge
and stop opening door once pressure reaches 2000 PSI.
4. Peak performance is obtained by matching your highest continuous auger
rpm to the flow door opening setting. It is necessary to initially monitor the
auger speed and adjust the flow door UP or DOWN to arrive at the optimum
output performance. If the flow door is opened too wide, the oil pressure will
rise, but the GPM and the hydraulic motor RPM could slow down - resulting in
less auger output. Also if the tractor has a higher GPM output, it is possible that
the flow door could be opened wider and still maintain performance.
5. Bushels-per-minute output depends on the following factors:
a. Oil flow (GPM) from tractor.
b. Flow door opening setting.
c. Grain moisture content.
6. The hydraulic motor is capable of handling 32 to 35 GPM. If extra hydraulic
ports are available on the tractor, it is possible to increase oil flow to the
hydraulic motor by teeing together two pressure ports to the single pressure
hose, and teeing two hoses from return hose to the tractor return ports.
