Bleeding the Hydraulic Lift System

Unfold the planter, raise and lower it several times to help force trapped air toward the tractor or wheel module cylinders.

Lower the planter on level ground, remove clamps and collars (A) from front of master cylinder.

With the collars removed, the wheel modules can then be bled by one or two persons. If only one person is bleeding the wheel modules, proceed as follows:

CAUTION: When bleeding the wheel modules, open the bleeder valve slowly to prevent injury from hydraulic oil, or from sudden wheel movement.

With planter in raised position and tractor engine shut off, place remote cylinder operating lever in neutral, install bleeder hose (A) on bleeder valve. Bleed trapped air from each wheel module cylinder (alternating sides of planter), allowing planter to lower and oil to flow until it is free of air foam. Repeat as required.

IMPORTANT: Be certain to alternate sides of planter when bleeding wheel module cylinders to prevent row units from dragging sideways on the ground.

When all the trapped air has been removed from the wheel modules, fully raise the planter and hold the remote cylinder operating lever rearward approximately five seconds. Lower the planter and replace the collars.

If two people are bleeding the system, proceed as follows:

Move the remote cylinder flow valve lever (A) to the "tortoise" position.

Throttle back to 1500 rpm or less.

Raise the planter and hold the remote cylinder operating lever rearward.

CAUTION: When bleeding the wheel modules, open the bleeder valve slowly to prevent injury from hydraulic oil, or from sudden wheel movement.

Have second person install bleeder hose (A) on bleeder valve. Bleed trapped air from each wheel module cylinder until oil is free of foam.

If the oil is caught in a clean container and is not contaminated, it can be poured back into the tractor. However, if the oil is quite foamy, allow it to stand until the air is gone before pouring it back into the tractor.

Check the oil in the tractor and add as necessary.

Move the remote cylinder control valve lever back to the "HARE" position.

Raise, fold, unfold and lower the planter several times.

Recheck the wheel modules to be sure you have removed all trapped air and foam from the lift system.

Replace the collars on the master cylinder.
