OPERATING INSTRUCTIONS
Designed Use
The folding pulverizer is designed to pull behind wide model field cultivators and discs. It can be used as an indi-
vidual unit with the tractor to prepare a seedbed or after seeding to break down and pulverize large surface clods.
The long drawbar allows for easy, short turns when pulled behind other equipment.
Bleeding Hydraulic System
The first time the machine is connected to the tractor, or any time the hydraulic circuit is
opened, air must be bled from the system. Care must be taken not to raise the wings up
over center before they have been run part way up 7 or 8 times. The wings depend upon
the passage of oil through a flow restrictor to keep from free falling. If the cylinder is not
full of oil the wing will drop and may cause damage to the machine.
Bleed the system by removing the rod end pins from the wing fold cylinders, loosening hose ties as needed, and
turning those cylinders so the rod ends are upward. Then, fully extend and fully retract all cylinders five or six times.
Rod ends may then be reconnected to the lift links. It takes approximately 5 U.S. gallons of oil to fill the hydraulic
systems. Check your tractor oil level to avoid damage.
If the wings were folded to start with, use the same procedures of lifting the wing part way, except start unfolding at
the wings and then refold them.
Change the machine from field position to transport position 2 to 3 times to insure proper functioning of the auto-
matic transport lock.
Hydraulic Lift
This machine is hydraulically controlled by one circuit which controls the lift of the machine and folding of the wings.
CAUTION: Escaping hydraulic fluid under pressure can have sufficient 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 fluid 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 excaping fluid, see a doctor at once. Serious infection or reaction can develop if proper
medical treatment is not administered immediately.
The sequence for the hydraulic circuit is as follows:
To transport position:
1. Machine raises on transport wheels.
2. Wings fold and automatic transport lock is pulled into locking position.
