Hydraulic Tooth Control
System
The Puliv-Mulcher is equipped with Hydraulic Tooth
Control System which controls the Tines, either full
engagement or completely out of the ground.
1. Be sure the system is fully charged with hydraulic oil
before raising and lowering the Tines. The system
needs to be charged with oil initially and any time the
system has been opened for repair such as cylinder,
hose, or fitting replacement/repairs.
2. Check to make sure the tractor hydraulic reservoir is
full of the manufacturer's recommended oil.
3. Fully extend the Tooth Control Cylinders and continue
to hold the lever until all cylinder rod movement stops.
Retract and extend the cylinders about 5 or 6 times to
purge air from the system to verify that all cylinders
are working simultaneously throughout the stroke.
4. Do not loosen any hoses or fittings. Recheck tractor
reservoir to make sure it is within operating limits.
Tooth operating depth is controlled by 4 hydraulic
cylinders equipped with depth stops. Always raise the
machine into the full transport position before operating
the machine to release the stop valve and allow the tooth
control cylinders to retract to the preset depth. In
operation, the transport cylinders must be completely
retracted. This in turn retracts the small drawbar cylinder
permitting the drawbar to flex and providing the necessary
hydraulic pressure to hold the tooth control cylinders in
the preset position.
The Tooth Control Circuit requires approximately
1-1/2 gallons of oil.

TABLE OF CONTENTS
General Operation
1. The minimum horsepower requirements are typically
6-8 horsepower per foot. This will vary widely due to
speed, depth, moisture, residue and types of soils.
Local dealers can help in making recommendations
for your areas.
2. Operating speed is typically 5-8 mph. Excessive
speed can cause rapid sweep/point wear. Reduce
speed in rocky conditions to prevent wheel breakage.
3. Lift wheels must always be in raised position. It is not
necessary to raise machine up on transport wheels
during turns. Pulverizer wheels are used to gauge the
depth of each frame section.
4. Do not turn with the teeth in the ground, this can put
excessive side load on the Tines. Raise the Tines
slightly using hydraulic tooth control when making
turns to prevent bent or broken Tines, additionally
excessive side load can also bend the Tine Tubes.
5. Allow just enough looseness so each wheel will turn
by itself. If wheels become worn, loosen the clamp at
the end of each roller axle and tighten as needed. See
Figure 4-2.
6. Always raise and lower the Wings with the machine
raised into transport position to ease the side load on
the roller bearings and the end roller clamps.
