OPERATING INSTRUCTIONS
Designed Use
The folding pulverizer is designed to pull behind wide model f eld cultivators and discs. It can be used as an
individual unit with the tractor to prepare a seedbed or after seeding to breakdown and pulverizer large sur-
face clods. The long drawbar allows for easy, short turns when pulled behind other equipment.
Tractor Preparation
Lock tractor drawbar in center position. Do not allow the drawbar to swing, especially during
transport.
Pulverizer Preparation
Hydraulic oil capacity of pulverizer is approximately 2.0 gallons.
Clean hose f itting before connecting to tractor. It is also necessary during initial operation to watch tractor oil
level closely to avoid damage.
In feld working position with the three cylinders at the end of their stroke the wing gang will be able to f oat
which allows them to follow the ground contour. At the same time the axle tires will be raised 4 inches off the
ground to avoid making tire tracks on the pulverized field.
Bleeding Hydraulic Cylinders
CAUTION: Escaping hydraulic f uid under pressure can have suff cient force to
penetrate the skin, causing serious personal injury. Relieve pressure in hydraulic lines
before uncoupling hydraulic hoses from tractor. On most tractors this can be done by
operating valves after engine is stopped. Before applying pressure to the system, be
sure all connections are tight and that lines and hoses are not damaged.
Hydraulic fuid escaping from a very small hole can be almost invisible. Use a piece of cardboard or a
piece of wood, rather than hands, to search for suspected leaks.
If injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop if proper
medical treatment is not administered immediately.
Bleed the air from the hydraulic system before moving the machine. Bleed the air from the transport system
frst. This can be done by partially raising and lowering the machine slowly 5 or 6 times. Gradually increase
the length of stroke until the last two cycles are the full stroke on the cylinder.
Bleed the air from the wing folding system next. Raise center of machine, then push transport lock down.
Tighten the 1” nut in the transport cylinder anchor to hold the center up. For machines with manual transport
lock place or remove transport lock on hydraulic cylinder instead of tightening or loosening 1” nut. If the wings
are unfolded, begin partially folding them and then unfolding t hem again. When unfolding hold the tractor
valve to get the most oil in that side of the cylinder. Be careful that neither wing goes over 90°. Repeat this
process 8 or 9 times gradually raising the wings closer to 90°. After bleeding procedure is complete loosen 1”
nut in the transport cylinder anchor to allow free movement.
If the wings were folded to start with, use the same procedures except start unfolding at the wings and then
re-fold them.
If it becomes necessary to drain the oil from one or more cylinder, it is important to bleed the air out of the
system before operating.
Change the machine from field position to transport position 2 to 3 times to insure the automatic transport lock
is functioning properly.
