Cannot adjust weight
transfer: (Green Handgrips)
Reset flow on tractor and readjust weight transfer, per operating manual.
If valve is opened completely and lower pressure to wings is desired reduce tractor
flow rate further.
If tractors flow is still too high to adjust weight transfer be sure to set flow so it is
running no more than 1500lbs, 1000lbs is preferred.
Turn the weight transfer knob while running active hydraulics. The audible tone
should change with every turn of the knob. If not the bypass valve is faulty.
