Thinking about mounting our martin side slinger manure spreader on a truck for some hayfields too far for a tractor. Was wondering the best/easiest way to go about powering the pto shaft on the spreader. Also need to have hydraulics to open the door to let the manure out to spread. Saw a pto drive motor on surpluscenter.com that looks like a simple setup but not sure how to match to the pump on the truck. The truck has a dump pump on it now.
