Hey All, I built this thing out of a small manure spreader a few years back. Really all I did was remove the beaters from the manure spreader and then bolt on a treadmill for the side dump conveyor. The unfortunate thing is I built this thing starting with a manure spreader that is ground driven. So this means that I am locked in to a particular speed of the apron chain (a kind of conveyor that pulls the wood chips to the back of the wagon). I would like to convert the drive mechanism of the apron chain to hydraulic drive, but I do not know how to select the right hydraulic motor size or rating. An older farmer stopped by today and said that he figured 20 or 30 hp would do the trick, but I don't know how many foot lbs torque rating to look for when buying a motor. How much do I need to gear it down to get the right speed? (very very slow!) What do I use for a speed controller? Do I even need to gear it down? Do hydraulic motors have all their torque at low rpm?
I had my wife take a video of the tool a few years back. Unfortunately no matter how hard I try I simply cannot seem to get her to keep the camera on the tool and off the scenery. This is the best I have got.
Thank you for any help hyraulic gurus! I wanna start building with hydraulic motor power!
