Note:

Do not raise auger in high winds.

1. Start with the tractor's hydraulic oil level in a normal operating range.
2. Add

about

4 L (1 US gallon) to the tractor's hydraulic oil reservoir.

3. Start tractor, then raise auger until the lift-assist is fully extended and track

shoe has moved about 1’ from trackstop.

4. With tractor still running, lower auger to full down position.
5. Repeat steps 2, 3, and 4 until about 19 L (5 US gallons) have been added

and tractor hydraulic oil level in the reservoir remains within the operating
range.

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 8.3).

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
Wheatheart Manufacturing.
