I have recently bought a wd tractor that has a AC hydraulic cement ram attached on the back of it. It has a special frame that is connected to the frame behind the front wheels and goes towords the back and is attached to the axles also and the seat is also mounted on the frame as well as the hydraulic valves and controls for the ram. The fenders are also mounted on the frame and they are spaced wider than usual because of it. The hydraulic pump that runs it comes out of the front of the tractor and it also has a big hydraulic tank (around 10 gallon capacity) placed to the left of the engine. If anyone knows more about this attachment or how it works I would like to know. I am also wondering if it changes any of the controls to operate the tractor or how it would normally function. I know this implement it probably rare and I am also wondering what it is worth.
