Twist in pto shaft

motionclone · Feb 21, 2019

Got a little problem with the pto shaft that came with my new to me LP 2572 finish mower.

Can I get this shaft material somewhere or do i twist it back somehow. Its still surprisingly flat, 1/16th " bend in it.

How about the plastic safety housing? Is that something I can get to replace whats missing?

Trying to avoid buying a whole new assembly .

A couple years ago I went to a local dealer that sold agricultural trailers and axles, he sold that material by the length or you might try a shop that repairs driveshafts. If you find shaft they may also have the plastic.

If it isn't cracked and doesn't vibrate I would use it as it. Just keep an eye on it.
I'm sure you can find the tubing for it it make one yourself.
I would think you can find a new one for around $100+.
After you are finished re-vamping the mower you may think it's worth it.
The replacement sleeve alone may cost you half of that.

When the the shaft is twisted like that, it throws the clocking of the joints out and will vibrate and bind, so not a good thing.

I have a local farm store that I can get parts like that, but pricing out a new cover and shaft you're better off just spending a we bit more and getting a complete new shaft, and if you don't have the clutch for it, get the shaft with the clutch to prevent the new shaft from suffering the same fate.

I was going to the the exact same thing; and add that maintaining the clutch is always a good idea as well. LP's owner's resources both online and on paper outline it.

I should have caught that. I have to reconsider my answer and agree with Wolfman....unless somehow you can have it straightened or "un-twisted". But I would suspect that heating it to straighten it would make it more likely to twist again. I am wondering if it wasn't bent at one time rather than twisted and the efforts to straighten it left it twisted. Who knows?
A machine shop may be able to re-align it or you if you have the equipment and the knowledge. But if you have to pay someone to do it and then buy the plastic shield I suspect you are getting into the price range of a replacement shaft.

Appreciate all the input. I think Im going to look around for a replacement shaft. Dont want vibrations.

Ditto twisted shaft gets u-joints out of phase.

ASC Agri-Supply www.AgriSupply.com has them pretty cheap. I've bought more than one replacement from them in the past. Much better pricing (shipping included) than Tractor Supply and light years cheaper than the local dealers.

89797 is a good example and comes with a slip clutch.

TSC sells replacement weld on shafting if you are handy with a welder. You'll need to replace the male and female however as both are twisted.

Even if the existing shaft is usable, or you can replace it yourself, I suspect this would include cutting and welding the replacement in place. At best it would be better, but not as accurately aligned as a factory assembly.

You don't want something like this to put undue stress and ware on your tractor pto bearings, clutch, seal and other parts.

There is a time and place to DIY, or find a cheaper alternative. To me this isn't it.

My 5 cents of opinion.

Does look like good prices at agrisupply. Couple questions though. How do I know what length to get? Measure the distance between pto out and spindle on mower then add XXX amount for overlap?

The original mower came with no slipper clutch according to the manual, do i really need one? Is the pulley to belt friction supposed to be the give? (belt slips when hit object)? The pulleys were all rusted up when I got the mower so maybe they were sticky from the rust scale

Sorry, gave bad info, seen mower, not finish mower, yes you are right no slip clutch needed.

Shaft length is PTO to shaft, make sure it's shorter than max length ( Example: you measure 54" get a shaft that will shrink to 50" to be safe) or you will drive the PTO shaft right through the tractor (that's really bad), and make sure it's max working length is more than needed.

If you don't find one short enough, you can always cut them down, you just pull the sheilds off both sides and cut equal length off of each end.
