Hi, yesterday I ran my tractor for an hour or more while I used an atv winch to pull my chicken coop up onto a trailer to transport. Well thats a little beside the point, but you know people like to hear what you did with your GT today.
So as I pulled away with the coop loaded (among the heaviest loads it's ever pulled) the mowing deck started spinning. I clicked the PTO switch back and forth a few times, when it was on the blades of course went full speed, and when off, they surged back and forth a little, but did pick up to feel speed.
So the PTO is dragging. Later in the garage I shut down the engine, removed the belt and turned the PTO by hand. There was obvious friction and a nasty grinding noise. Then I flipped the switch with (engine still off) and turned again. The PTO was locked and with the little force I could produce I could feel the cylinders moving. It's sounds better with the PTO engaged.
The tractor is a Deere 317 with a Kohler Magnum 18, restored and repowered, and bought at auction, so I don't know poo about the history. It's been a lovely machine and super reliable so far.
So where should I start in fixing this? Would a new PTO unit solve it, is the dragging bearing or surface likely to be housed in the PTO?
Is there any harm in using the tractor with nothing attached to the PTO and always on?
