Rotation speed of the Topdresser brush can be mea-
sured with a rotating contact RPM indicator to see if
brush motor performance is correct. Before performing
this test, the System Flow Test should be completed to
make sure that hydraulic flow from the wheel motors is
correct.
NOTE: If system flow and brush RPM are correct and
conveyor is not operating correctly, thoroughly inspect
conveyor rollers and bearings for wear or damage. If
conveyor components are found to be in good condition,
consider that the conveyor motor needs repair.
NOTE: The brush motor rotation speed will be affected
by brush bearing condition and/or binding of the brush
assembly. Make sure that these items are checked be-
fore proceeding with this test procedure.

Procedure for Brush Motor Efficiency Test:
1.
Perform System Flow Test to make sure that wheel
motor output (flow) is correct.

IMPORTANT: Make sure to thoroughly clean around
all hydraulic connections that will be disassembled.

to allow accurate testing of the brush motor:
Remove conveyor motor from the hydraulic system

Hose (supply) to conveyor motor
Hose (return) to hydraulic manifold
A. Disconnect hydraulic hose from the straight hy-
draulic fitting on the brush motor (Fig. 24). Install a
clean steel plug into disconnected hose end.

B. Disconnect hydraulic hose from the longer elbow
fitting on the conveyor motor (Fig. 25). Install a clean
steel cap onto the fitting.
C. Pull hose that was disconnected from conveyor
motor through hole in frame. Connect this hose to the
open fitting on brush motor to allow a complete hy-
draulic circuit for brush motor operation. Make sure
that hose is safely positioned away from the brush
and other rotating machine parts.

Turn the Topdresser control handle switch to the ON
position.
Start engine on tow vehicle and tow the Topdresser.

While operating the machine, monitor the vehicle
speed and the brush rotational speed using a rotating
contact RPM indicator. Brush speed is dependant on
ground speed and should be as shown in the chart to the
right (Fig. 26).
Ground Speed
Brush RPM
160–180 RPM
245–270 RPM
325–360 RPM
405–450 RPM

If system flow is correct and brush RPM is low, con-
sider that the brush motor is worn or leaking internally.
