This unit is based on a Meyers E-47 12 volt snow plow pump (6" stroke) that I put together about 10 years ago to use on my JD 650 tractor. For front end hydraulics all you do is connect two leads to your tractor battery and stick the up/down and Left-Right angle switch box to the tractor (Switch box has a magnet). The pump has drip less connectors and was test run recently after a few years storage and everything works as designed. Not shown in the pictures is additional mounting iron used under the tractor. This can be modified to fit your application. The Meyers E-47 pump is an older model but all parts are still available. The 6' blade that I used is no longer available.
(The red iron in the picture is a small hand cart used to move the pump around).
