Seasonal Disconnect

So this evening after yarding some hay, I pulled the old 300 in the shop and had the thought of disconnecting the pto. It makes a gawd awful racket when the pto isn't engaged. So under I went and now, I'm stumped. The book says pull the lever back. It won't go back but 1/2 an inch. Its in the rearward hole already. PTO works fine, by the way. Try to shove it forward, no go. Solid as a rock. So what gives? Was the coupler removed some time in the past and straight shafted? Could the unit have been rebuilt and the lever put back in wrong way round? I confess I'm stumped on this. The old SMTA just popped out pretty as you please. Any advice?

Some of them wear the coupling and jump out of gear when used. Owners then move the coupling together and spot weld it, or clamp the coupling in place. There are several farmer methods. Jim
 
Thank you Jim. I was hoping to hear from you. I wonder, would new brake disks stop the whining? I've taken the wretched things up until I'm nearly out of threads. Or maybe not? It makes a terrible whining as it is, and I'm only going to be needing it about once or twice a year mowing. Thanks for the advice.

I've heard people say it is best to leave the PTO run all the time. Quieter and less wear and tear on the brake.
 
If I recall the bolt will be in rear hole engaged and front hole of lever disengaged. Lot of times when drive dogs were replaced with a solid coupling the internal disconnect lever was removed and the external lever will move wherever unless they spaced the end of shaft so internal nut tightened shaft and lever. But dogs could be welded or a clamp put in to hold dogs engaged. If the shift lever is forced very much the internal lever on end of shift shaft will get messed up. PTO noise is caused by bearings and planetary gears spinning. Brake bands should only wear when shifting or out of adjustment and slipping. Linning does come loose sometimes.
 
Right, and its opposite of that now. Which makes me think its been fiddled with at some point. Ah well, I think I'll just leave it go for now. By the sound of it, the gear whine wouldn't have been cured anyway.

Thanks, Mac
 
If it works and you can spin the PTO shaft when the lever is midway between off and on, all is well. The Bands don't make noise, it is the gear sets inside it. Jim
