Opener Hydraulics - Continued
Pressure Adjustment (On the Go) - Continued
Pressure adjustment on the go
, requires input from the operator to function.
The operator will have selected the operation valve to be in the bleed off/service position.
The adjustable reducing valve (Pressure Valve) will be set to provide correct trip and packing pressure.
With the Contour Air Drill moving forward, lower openers into the ground. Hold tractor hydraulic lever until the maximum
preset operating pressure is reached. This ensures that all of the openers are fully charged and engaged. To reduce
operating pressure on the go:
• Place tractor hydraulic lever into “Float Position” until pressure drops to desired operating point.
• Release hydraulic lever once desired pressure is reached.
Note: If pressure drops too rapidly when tractor remote is put into float, the “Operating” valve can be turned
in a few turns to reduce bleed-off speed.
To increase operating pressure:
• Operate tractor hydraulic lever to increase pressure.
With the tractor lever in the float position the pilot operated check valve does not receive
any pilot pressure to open it and the directional lock out valve does not receive any
pilot pressure to close it.
The oil flows from the accumulator and the butt end of the opener cylinders through
the operation valve and the one way check valve back
to the tractor. When the tractor hydraulic lever
is released the oil is again trapped and the
pressure will be reduced. If the pressure
reduction is too great the operator will have
to pressure the system up to the desired
pressure.
