Opener Operation
Crushing Hazard:
Keep all persons well away during drill operation. You will be
seriously injured or killed if you are caught between raising
openers and drill frame. Always stop tractor engine, set
parking brake, and remove key before adjusting or servicing
openers.
The openers are raised and lowered on their own
hydraulic circuit. When used with an active hydraulic
system, constant hydraulic down pressure is placed on
openers for even soil penetration across the drill. To
operate openers with live hydraulic power, always
connect the opener-lift hoses to the circuit designated for
hydraulic-motor control.
To achieve proper opener flotation, the opener hydraulic
circuit must be powered by an active hydraulic system.
An active hydraulic system requires a tractor with
closed-center hydraulics or pressure-flow compensated
hydraulics powered by a variable displacement hydraulic
pump.
To run drill on tractors with open-center hydraulics or on
tractors with fixed-displacement hydraulic pumps, you
must install a Great Plains kit, part number 194-143A.
Contact your Great Plains dealer for ordering
information.
If you are not familiar with your tractor’s hydraulics,
consult your tractor dealer.

High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Check all hydraulic lines and fittings before applying pressure.
Relieve pressure before disconnecting hydraulic lines. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Fluid escaping from a very small hole
can be almost invisible. Use paper or cardboard, NOT BODY
PARTS, to check for leaks. Escaping fluid under pressure can
have sufficient pressure to penetrate the skin causing serious
injury. If hydraulic fluid is injected into the skin or eyes, seek
immediate medical assistance from a physician familiar with
this type of injury. Within a few hours gangrene can start to
develop. DO NOT DELAY.
