11.3 Operating the Windrower
When ready for field use be sure to remove the drum transport pin. After completing field work always prepare
machine for road transport be reinstalling the transport pins.
Then set the working depth of the windrower teeth to desired level. Do this by screwing the depth stop collar on
the drum of the hydraulic cylinder in or out.
In order to protect the driveline against excessive shock loads a shear bolt is provided on the universal joint
assembly between the gearbox and chain case. Should the shear bolt break during operation replace as
outlined in the 'Maintenance' section of this manual.
Fully raise the drum off the ground BEFORE engaging the PTO. Failure to do so could result
in shear bolt breakage.
Do not exceed 5 mph (8 km/h) while operating the windrower. In heavy rock conditions reducing your forward
speed will ensure that rocks are not skipped.
If too much dirt is being carried into the windrow, reduce the working depth. The axle plates can also be
adjusted up or down to bias the working depth to one side or the other. Typically the axle of the right leg on the
pivoting wheel standard is set 1" lower then the left leg. This is to help bring material to the surface.
If large rocks are being carried into the windrow, slow the tractor rpm.
12. Roadside Operation
The axle on the left side of the windrower must be
set ¾" lower than the axle on the right side.
Running the discharge end of the drum slightly
higher allows smaller material to drop out as the
ridge moves across the drum. Only grass will be
left, which will dry and blow away.
The windrower should never be operated on the
center (crown) of the road as this will cause
excessive wear of the hard surfacing on the teeth
near the center of the drum.
Only skim the surface of the road when moving the
ridge from the side of the road to the center. Letting
the teeth "hammer" the surface of the road will
cause accelerated wear of the hard surfacing.
The drum should be checked frequently for wear.
Teeth must be hard surfaced before the bare tooth
is exposed. If the hard surfacing is not properly
maintained, highly accelerated tooth wear will
result.
