Filtering the Closed-loop Traction Circuit (continued)
Field Pro® 6040

Use caution when performing this procedure. The rear wheels will
be rotating during the procedure.
While engaging the traction circuit, monitor the indicator on the
high flow hydraulic filter. If the indicator shows red, either reduce
the pressure on the traction control or reduce the engine speed to
decrease the hydraulic flow through the filter.
8. With the engine running at low-idle speed, slowly move the traction control
to the reverse direction for a piston (traction) pump failure, or to the forward
direction for a wheel motor failure to allow flow through the traction circuit and
high-flow filter. Keep the traction circuit engaged for 5 minutes while gradually
increasing the traction control pressure and the engine speed. Monitor the
filter indicator to ensure that the green color is showing during the operation.
If you are using a filter that is not the Toro high flow filter that is
bi-directional, do not press the traction control in the opposite
direction. If the flow is reversed when using a filter that is not
bi-directional, unwanted material from the filter will again enter the
traction circuit.
9. When using a high flow bi-directional filter, alternately move the traction
control in opposite directions with the engine running at high-idle speed.
While monitoring the filter indicator, continue this process for 5 more minutes.
10. Set the key switch to the O
switch.
11. Remove the high flow hydraulic filter and hydraulic hose kit from the machine.
Flush clean and install the preciously removed hydraulic tube; refer to
Installing Hydraulic Hoses and Tubes (O-Ring Face Seal Fitting) (page
12. Install the rear wheel; refer to
(page 7–5).
13. Check the hydraulic fluid level in the tank and adjust if necessary; refer to
the traction unit Operator's Manual.
14. Operate the machine and check for leaks before returning the machine to
service.
