ASSEMBLY
Purging the Hydraulic System

WARNING
Figure 2-26: Hydraulic Leak Detection
The hydraulic system is not filled with oil and should be
purged of air before transporting and field operations.
Carefully hitch the Pulvi-Mulcher to the tractor and
connect the hydraulic lift hoses. Check to make sure the
tractor hydraulic reservoir is full of the manufacturer’s
recommended oil.
Purge the Lift Cylinders
Slowly raise machine and continue to hold hydraulic lever
until lift and leveling cylinders are completely extended.
Lower and raise unit completely extend and retract
cylinders 5-6 times to purge air from the lift circuit. Do not
loosen hoses/fittings. Recheck tractor reservoir oil level.
Lift circuit requires approximately 4.1 gallons of hydraulic
oil and with machine lowered requires 3.7 gallons of
hydraulic oil.
Purge Fold Circuit
With fold cylinders disconnected from wings and blocked
up to allow for rod movement, connect fold circuit hoses
to tractor. Ensure tractor reservoir is full of manufacturer’s
recommended oil. Extend fold cylinders. Recheck tractor
oil reservoir. Extend and retract fold cylinders 5-6 times
or more if movement is not smooth or until air is purged
from the circuit. Fold Circuit requires approximately 5.9
gallons of hydraulic oil and with wings unfolded requires
7.2 gallons of hydraulic oil.
Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands. See
Figure 2-26. Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
