ASSEMBLY
Plumb Wing Tooth Control
Cylinders
1. Install fitting into 4 x 8 Wing Rephasing Hydraulic
Cylinders. See Figures 2-18 and 2-19.
2. Route Wing Tooth Control hoses from center frame
along front of wing frame to wing cylinders. Wrap both
hoses together with 26" hose wrap at hinge areas.
3. Secure all hoses with Cable Ties and Tie Wraps.

Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching

TABLE OF CONTENTS
Purging the Tooth Control
Cylinders
Pulvi-Mulcher Tooth Control Cylinders are series
cylinders that rephase on retract.
1. The hydraulic system is not filled with oil and should
be purged of air before transporting and field
operations. Check to make sure the tractor hydraulic
reservoir is full of the manufacturer's recommended
oil.
2. Raise Machine. Slowly raise the Shanks, and
continue to hold the hydraulic lever until all Tooth
Control Cylinders are fully retracted. Lower and raise
the shanks to verify that all cylinders are working
simultaneously throughout the stroke. If the cylinders
are not working evenly or together, fully retract the
tooth control cylinders and continue to hold the lever
to purge any remaining air.
3. Do not loosen any hoses or fittings.
4. Recheck tractor reservoir to make sure it is within
operating limits.
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.
