Checking "proper PTO shaft length" question.

[Runs With Scissors]

I tried searching but couldn't quite find what I needed.

When I originally bought my tractor, I purchased a QH-15 and had the dealer cut all the implements shafts.

Well I forgot to bring the the QH-15 back the last time, so its uselessly sitting on the floor in the pole barn.

I want to use the tiller this weekend, but I'm concerned that without the QH-15 the shaft might be too long and cause a binding situation.

I was thinking of hooking it up and "turning it by hand" (with motor off) to check for binding.

Does anyone have a better/proper suggestion?

You could consider raising the 3-point with tiller installed, collapse the driveshaft and lay the coupling on top of the PTO shaft, the do the same in the fully lowered position. Be reminded that when operating the tiller, it be lower than when just sitting on the ground.

Raise the implement to the point the distance between the ends of the PTO shafts is the shortest.

An easy rule of thumb is you should be able to install the PTO shaft at this position. If you can't, I'd take the safety covers off to measure the actual PTO shaft overlap distances and make sure you aren't hitting the limits.

Good day. I am not aware of a simple way to measure or trim the PTO shaft with your backho , so I’d start by watching this video. I’ve seen your projects and you have the tools and are more than capable….it’s a simple mod. Honestly I’d hook it up and check the measurements and math first and see where it. Unless you checked it, it’s hard to guess who/what did the cutting at the dealer and did they use the correct dimension. Anyway I’d check the math (maybe it’s fine as long it sits…you don’t know unless you check) and if necessary give it trim. Keep in mind it’s more difficult to uncut it if you plan To put back on with the QH….only you can decide that one. They’re nothing like a well kempt shaft.

I've always done the 'turning-by-hand' method, though that tractor has pure 'mechanical' PTO so it 'freewheels'. seems a lot of Kubs have 'clutched' PTO shafts and don't 'freewheel'.

Thanks guys.

I forgot that I have to grab the boat for a fishing trip next week, so my SIL would have to do this.

I guess he will just have to wait to till his food plots until I get back with the QH-15.

He's a good guy, but kind of a knuckle head as far as "mechanical things" go, and if he busted the shaft on the General Lee's PTO, I'd be in prison for ....well....you know.
