OK, let me start by saying I have a spare Gravely L, and a warped mind. I am also into boat building, so I figured I would put the two together. I am thinking of building a wooden skiff, and installing the gravely tractor to power it. It could be doable. It would give me forward/reverse, and a high/low speed. I figure I would sit the unit sideways, and attach the prop shaft to the axle output. This would also leave the PTO hookup on on the tractor to power a winch, or something else. What do you think? Am I strange, or does this sound like a good idea? I figure with the low speed, and high tork, I would need a good size prop, but I think it may work.
