Intake feed hopper speed is regulated by the volume and pressure generated by
the hydraulic system of the tractor. When tractor engine rpm is increased, the
speed of the flighting in the hopper is increased.
The speed of the main auger will also increase, effectively preventing the
overloading of the main auger under normal conditions. If the intake feed hopper
is overloading the main auger, decrease the amount of grain flow from your truck
or trailer.
For proper intake feed hopper function, the hydraulic motor must receive
adequate gallons per minute (gpm) at the proper pressure (psi). The minimum
volumes and pressures are:
• The 10” intake feed hopper must receive a minimum of 10 gpm (45.5 lpm) at
1500 psi (10,342 kPa).
Note:
The minimum requirements listed are essential for efficient auger operation.
Additional gallons per minute will increase the speed of the hydraulic motor
(flighting rpm) while a higher pressure will create additional torque to maintain
motor speed under load.

Do not exceed a constant back pressure of 300 psi (2068 kPa) in the hydraulic
motor.
• The hydraulic system on some tractors is designed so that the return flow
of hydraulic fluid from the hydraulic motor to the tractor is restricted. This
creates excessive back pressure inside the hydraulic motor and deprives
it of an adequate flow of hydraulic fluid. The result will be
seal failure,
overheating, rough running,
and
loss of power
.
To date, these problems occur primarily with certain John Deere tractors. Kits to
correct the problem are available from your John Deere dealer (Figure 8.1).
Important:
John Deere Series 50 tractors with a single hydraulic lever will require this kit.
Series 50 tractors with double hydraulic levers have the kit pre-installed.
Note:
The problem discussed in this section may exist on tractors other than the John
Deere. Should you experience this situation, contact your tractor dealer or
Westfield Industries.
