OPERATION
To fold the Pulvi-Mulcher, stop and raise the machine with
the hydraulic lift system. Engage the fold system circuit on
the tractor to retract the Wing Cylinders until the cylinders
are completely retracted and the Wing Frames are resting
on their bumpers.
The Fold Circuit requires approximately 6.0 gallons of
hydraulic oil with wings folded and 7.2 gallons of
hydraulic oil with wings unfolded.
Hydraulic Tooth Control
The Pulvi-Mulcher is designed with hydraulic tooth
control. The cylinders in conjunction with the Shank Depth
Control are used to control shank position. Each tooth
control cylinder has an adjustable anchor bolt.
1. To set the anchor bolt unfold Pulvi-Mulcher, machine
raised, with all tooth control cylinders fully extended.
Shanks should be set with tooth tubes parallel to the
frame. See Figure 3-4.
2. If Tooth Tubes are not parallel to the frame, check
measurement from the center frame tube or wing
frame tube to the cylinder pin. See Figures 3-2 and
3-3. Note the dimensions shown are a starting point.
3. Adjust the Cylinder Anchor Adjustment Nuts until the
tooth tube is parallel to the frame. Be sure both center
frame cylinders anchors are set the same to ensure
left side is synced with right side.
Circuit utilizes rephasing cylinders that rephase in the
retract position. System can be air purged or rephased by
retracting cylinders or raising shanks and continue to flow
oil for an extended period of time.
The Tooth Control Circuit with shanks raised requires
approximately 2.3 gallons of hydraulic oil, and with
shanks lowered requires 2.6 gallons of hydraulic oil.
Shank Depth Control Adjustment
1. A more precise adjustment of the Shanks can be
made using the Shank Depth Control. The "F" setting
refers to the maximum operating depth. See
Table 3-2.

If making adjustment all Tooth Tube Bearing should be

2. Adjust the Shank Depth by turning the Depth Stop
Handle until the desired letter that matches the
required shank depth is centered on the depth Stop
Indicator. See Figure 3-4.
