LOWER Moldboard/FLOAT MODE
Lower Moldboard / Float Mode
See DWG. NO. 4117
When the joystick is moved to the down position
power is supplied to P2-2. This wire is connect-
ed though the P1-3 J1-3 connector to the down
solenoid S3 located on the plow power unit. Bat-
tery ground is provided through the P8 J8 con-
nector to the power unit housing.
Turning on the down solenoid bleeds the oil
from the up cylinder, back into the oil tank as the
weight of the plow moldboard pushes against it.
The down movement latches the down solenoid
on, also called float mode, so that the moldboard
can rise and fall with the surface being plowed.
A raise movement will turn off the down solenoid
and cancel the float mode.
