That's an E-46. They're notorious for water getting into the base of the motor above the gear pump, and for the lift cylinder seal leaking. For any that have been left sitting for a long time with water contamination, they also stand a good chance of the lift cylinder surface being rust pitted and the piston being worn. It looks like this unit has had some work done to it, but it is impossible to say how far they went -- caveat emptor.
For that unit, you will note the solenoid in the base opposite the motor. This is the "down" solenoid. Throw +12v at that and the plow goes down. The terminal at the top of the motor is the "up". You will need a high current relay/solenoid to power that one.
They seem to have one of the pump base bolts rigged up as a ground terminal, which should be fine. The "designed" ground terminal is the bolt to the immediate right of the down solenoid (which they have painted over).
In theory, you can run this thing with just one SPDT switch. In practice, it can be a challenge to find one that is momentary contact in one direction and sticks in the other. Your best bet would probably be two SPST switches, one momentary for lifting, the other latching for lower/float.
IT DOES NOT POWER DOWN, it floats down, so you need to keep the down solenoid powered while plowing.
Also; aside from the missing power angling block, it is identical to an E-47.
This unit can be upgraded to an "E-56" by replacing the pump base and motor. E-56 would be considerably faster/more powerful. That would run you about $300 in NEW parts.
