Power Dump Option; Hi-Dump ® Option - Walker D21d Operator's Manual

Operating Instructions

Power Dump Option

When equipped with the optional power dump
system, the operator dumps the catcher while
sitting in the seat. A toggle switch operating a
power ram is used to raise and lower the catcher.
The back door automatically opens and closes
during the dump cycle.
Hold the toggle switch UP or DOWN to RAISE or
LOWER the catcher. When the catcher reaches
the full raised or lowered position, the power ram
clutch will make a ratcheting sound. Release the
toggle switch as soon as this sound is heard. DO
NOT operate the ram with the clutch ratcheting
for an extended time as this will cause extra wear
on the clutch mechanism.
The operator should be in the seat and by-
standers stay clear when the power dump
is operating. The power dump is used
ONLY for tailgate dumping. Do not attempt
to use the optional dump bag or any other
bag with the power dump.
NOTE: If grass tends to hang up in the catcher
after raising the catcher with the power dump,
"jiggle" the steering levers and make the tractor
bounce a little to unstick the grass and make it
slide out of the catcher.
NOTE: With the power dump mechanism in the
normal operating position (catcher down), the
catcher can be manually raised for access to the
engine and the catcher can be manually dumped.
