What to Do When Your PTO Shaft Won't Extend

- It's pretty frustrating when you get all backed up to the brush hog (or finish mower, or tiller) and get the three point all hooked up and you get ready to extend the PTO to get it attached and it won't come out. Then you're stuck with the tractor in the way of getting at a good angle to pull and yank on the shaft until it extends...and maybe it won't! The purpose of this video is to discuss why that PTO shaft won't come out and some options to resolve the situation.
There are two pieces to a PTO shaft. One end that has a larger "female" shaft inside and the other with the smaller "male" part that slides inside of it. When the shaft won't move in or out usually there are one of two problems present, one that you can repair and one you can't.
Let's talk about the bad one first, the one you can't repair. If the shaft is bent anywhere in the area the two pieces slide together, it's done. Best option is to go buy a new PTO shaft from your local dealer or farm supply store. Any "tweak" of ever-so-slight bend in those shafts and it's productive life is over. That can happen when the implement is raised too high and contacts the deck of the implement, or when the implement (usually a cutter) is driven through a ditch. Here's a link to a video where I show what can happen: • The Quickest and Easie...
Hopefully, if you have this happen, it's the other problem, and that is, they're just stuck. That happens a lot when the machine is stored outside and a little water gets in between those two shafts, forms some rust, and prevents them from sliding apart. In the video I give you a couple of options for getting them apart if that has happened. When you get them apart, make sure to keep a thin layer of grease on the parts that slide together from then on, hopefully you'll never have this problem again. Good luck!

Mine was stuck hard on a used shredder I bought.. I hooked a chain to the end of the shaft, ran it under the tractor to the bucket on the loader with the bucket swiveled down, and pulled the shaft out by swiveling the bucket up. Easy as it can be, even for 57 year old me.
Excellent. Looking forward to learning how the maintain the pto shaft. Us newbies really appreciate these vids.
My trick was to tie a tow strap around the end of the shaft and to the drawbar on the tractor and drive forward until it broke free and slid out. After I did this a couple times i figured out that storing the entire shaft in the shop with the two halves separated during the winter would keep it from seizing up on me
+Moto Shooter You're stealing my thunder...one of my future videos recommends taking the whole thing off if its going to be outside in the winter and storing it in the garage. You take it one step further by separating the halves so you can lubricate them as you're putting them back together. GREAT IDEA!
take the shaft apart and grease it really well and it won't stick and while you have the grease gun in you hand grease every thing that has a grease zerk, down on the farm we grease everything every month.
Thanks Mike, I was struggling with the same issue and was about to go buy a new shaft. You saved me a bunch.
Vibration and PBR Blaster worked for me. Tied a concrete vibrator around the shaft, lubed the shaft at the joint with PB Blaster and turned on the vibrator. A half hour later the shaft slid apart without further assistance. I've done the same using an electric pad sander.
lol I'm having this exact problem and it's even a brush hog! Thanks Mike!
Thanks. I think my PTO shaft is rusted. It's just not telescoping in and out properly. Thanks for the video and ideas.
I had a stuck PTO shaft recently. I discovered a fairly easy way to pull the stuck pieces apart. By accident I used an oscillating saw ( the ones that move a small distance but at 12,000 times per minute) to cut away a portion of the plastic shield to get penetrating oil between the male & female shats. After about 1 minute of cutting plastic, the shafts just fell apart. The saws vibration was transferred along the metal shafts and just broke loose that fast.
Thank you Mike, just sorted mine.
This is really helpful. Thank you Tractor Mike!
Awesome video. My Woods brush hog PTO shaft was stuck, and I just got it freed up from watching this. Thanks!@!!
Glad to help. That's what CZcams is best at...
I had to use the come along for a new PTO shaft that came with my rototiller that wouldn't extend . Then, it was a struggle to get it to close. Once I shortened it to fit the tractor, it worked fine .
Rookie from last video. Found your video on my trouble here. Thanks...i will probably need to replace the shaft.
Michael Schaefer if it's not bent no reason to replace it iv had pto shafts that I had a tractor tied to one end and a f 150 truck on the other dragged the pickup a good 20 feet before It broke free cleaned it up oiled it up put it back together and I'm still using it 10 years later
Thanks for the inspiration and keep on trucking!
keep the pto shaft lubed yearly. with grease and/or oil. I grease the male end (when in use) and lightly run oil inside the female end (for storage) to lessen chance of shaft freezing. plus I store my implements under cover as much as possible.
Mike, thanks for you'r time and effort, love the vidios
😂😂😂. The Bear Guy! Excellent choice!
Mike how do you remove the PTO from the cutter gear box? I have a 6' Land Pride and need to bring the PTO to the local shop - have yet to find any video that shows this in detail - thank you for the great vids!
I didn't know how complicated the connection between PTO speed,Engine RPM, and grown speed is until I had to explain it to someone. My dad just told use the seat of your pants that made perfect sense at the time.
I've had this problem too. It took a sledgehammer, motor oil, and grease gun.
My opinion if the male & female are frozen. Use a sledgehammer to jar it lose if possible. When it does move minimally, poor oil down the end of the outer shaft and keep using the hammer.
Thanks i just hooked my jeep driveshaft to my cherry picker all 2tons a litte heat an kapow done 👍🇺🇸
Did it make the sound "Kapow" when it came apart :)?
A local tractor shop is a total ripoff. They said they need to look at it to price repair, kept it three days and did nothing when I call them for some idea when they will get to it and an idea of price they said "next week $200". Therefore I picked it up before they robbed me. If you have a deep freezer (or plenty of room in any freezer) freeze it 48+ hours and pull it chained to a tree.
Thanks for the tip.
thank you for these very informative and useful videos! do you have a video on how to calculate per acre rate flow for sprayers ?
No. Growing up on an apple orchard you'd think I'd be an expert on sprayers and I'm not, but I know someone who is and I'll see if I can't get him involved in a future video series on sprayers. GREAT IDEA!!!
Can't get my 5140 John Deere PTO to flip to low RPM won't go in far enough for snap ring
Good video. Thanks.
Had a similar problem with the shaft for my post hole digger. the actual metal to metal shaft was able to slide into each other, but the guard ends were so tight that I couldn't pull them apart. Tried grease, silicone, even wax and nothing worked.
Thank you Sir!
Good info. I appreciate that
From what I have seen, you never talk about heating the shaft. Why is that? I have heard that is a good way to go. Also, should I take the shaft out over the winter when it just sits? thanks. Good videos.
If it comes off easy, pull the PTO off and throw it in the garage. I got that tip from a viewer and I think it is wise, especially if the implement is stored outside.
My problem is I cannot remove the telescopic shift from the yoke bought a Tiller and the shift is too short so I need to buy a replacement but don't need to buy the whole set up but I cannot get the shaft out of the yolk
i have the same model bush hog, thats a good one
can of Blaster overnight couple taps with Hammer wood block bam free shaft
Does a PTO shaft pull all the way out if one hooks up a puller to it? If it does then I could clean it easier.
I have a Squealer mower that I can't find the release to remove the drive shaft from the PTO. Any thoughts?
Connect one end to the tractor and the other end to a winch and pull it apart.
Clean it all up good and grease it.
If you can't raise the deck all the way without damaging the PTO shaft you need to cut the shaft down a couple of inches at a time until you can.
What do I do to keep the brush hog hooked to pto, do i need a new knuckle or pin?
i am trying to remove my pto shaft from my bush hog. I removed the big pin, but it looks like there is a washer clamp thingy that needs to be pried off. How do I remove the washer clamp thingy
Maybe it's a snap ring? It should be sitting in a groove and and can be pried off, but there's a special tool that spreads the ends apart for easy installation and removal. I'm guessing that's what it is, your "washer clamp thingy" description sounds like me trying to tell our boat repair place what needs to be repaired on our SeaRay :).
@@TractorMike that was it, thanks
Hey Mike how do you remove the pto from the bush cutter?
Detach from gearbox shaft. I had the same question on mine, and it has a slip clutch. Two bolts. None clutch should have one bolt.
Hello Mike I think that you said not to leave your PTO shaft end outside during the winter months or raining season. I installed a new shaft cover on my auger. I put the tractor end in my hay shed while the rest of the auger is attached to a large post. The lady at my local tractor dealer said not to separate the ends and always keep them together. What is the best way when storing the auger outside?
Tractor Mike
The other side is U-Joint connected to the auger. I have shoved white lithium up in the big end. I am going to place a trash bag on both sides. Thanks for your advice. I bought my first tractor 2 years after doing everything manually for years.
My PTO wont disengage when I move the lever to the off position. 2013 Kubota L3800. Seems like the cable is too loose. How can I adjust that?
I think if you go here: apps.kubotausa.com/illustrated-parts/ and enter your model number and find the PTO page you'll see how it is all put together and be able to see how to adjust it. The manufacturer's parts pages are lifesavers when it comes to figuring out how to work on stuff.
How does the shafts get bent going through a ditch? I mow my neighbors motorcycle dirt track with lots of dips and jumps. As a follow-on question, what is the proper way to mow in this type of situation?
This will show you: czcams.com/video/lRrGBu7MNvI/video.html. You're supposed to go through a ditch at an angle, not straight up and down, but if they're too steep the best advice is to avoid them.
My pto shaft on my bush hog is having problems extending and when I push it back. It's still new so I don't know why I'm having these problems. I spray WD40 on it and put grease on it to see if it helps but it still giving me trouble.
Any solve?
I've a hard time getting my new-ish shafts to extend. I was wondering about a lubricant, as I think the resistance is in the plastic guard. Perhaps silicon spray?
Thanks!
Hey Mike!
I've got a 67 AC D17 using an unknown brand of pull behind type rotary cutter. Cutting an old overgrown garden at the house, I hit a random, no point in being there, chunk of granite. In doing so, my PTO shaft twisted the sleeve coming from the cutter.
My question being; would it be possible to cut off and weld on a new piece of that sleeve since it only bent roughly 12"-15"? Or would I be better off to buy another PTO shaft?
There's probably a local shop in your area that does driveline repair that can fix it. Here's a video about what I did with a similar problem: czcams.com/video/ApnU87qOQh8/video.html.
What do you think of PTO extensions?
Would a small one cause increased wear on my driveline?
Are you talking about an overrunning clutch? That's the only PTO extension that I'm familiar with and I don't think they'd cause additional wear on the driveline as long as the shaft is not too long when one is installed.
Mike, I have a rhino rotary cutter with a driveshaft that will not extend. I tried everything to get it to work without success. So I decided to remove the shaft but I can get the ujoint off the gearbox shaft. It has a shearpin connection. I removed the shearpin but there is a collar on the gearbox shaft that will not let the ujoint slide off. Any idea how to remove the collar?
A lot of cutters will have a snap ring back there to keep the whole shaft from coming off if the shear pin breaks. Usually they're pretty fun to get out and then again to get back in without special tools. It could just be a ring, open on one end that that sets in a groove that can be pried out, its hard to know without seeing it. Guys that work on that stuff all the time can get those rings out easily, for the rest of us it's somewhat of an ordeal. Good luck.
How about connecting one end to a tree and the other end to your truck and pull?
Whatever works and is safe. Make sure it's a good sized tree.
I have a 1967 MF 150 gas, I cannot find neutral on the pto , how do you determine what pto drive you have ? It's my understanding they have 2 types ,
Well, it's either a "live" PTO with a two stage clutch, or, the less common, "independent" PTO. Have someone watching the PTO while you're running the tractor. Engage it, then push down the clutch. If it's "live", the PTO will stop with the clutch down. If it's "independent" it will be spinning regardless of where the clutch is and you shouldn't have to touch the clutch to engage the PTO, just move the lever back.
Tractor Mike ok thank you sir
How much over lap should I have on the ahaft?
Terry, the owner's manual should tell you based on the torque requirements of the implement. Usually 6-8" is minimum.
I just bought a 8 ft brush hog,the shaft refuses to move.i hooked it to a tractor and the back of my hoe.no luck!!I'm so aggravated. Unfortunately it set outside.Im going to let it soak overnight and try again
Bear guy. hehehe. Rent-a-bear for those especially beastly projects. :-)
He's back there. He's the one that eats all the donuts the tool-selling reps bring by...
Oh ya, I know who your talking about. He works right next to elephant guy, u know, the guy that works for peanuts, gentle demeanor. When he speaks up, though, he blows his own trumpet. Ya that guy! HA ba dum, bump. (sorry, just had to go therre!).
Mike, How do I determine the PTO series I have on my implement? Thanks,,,
I'm a little unclear on the question Harry. Do you mean what type of PTO shaft is on it? What are you trying to do and we'll try to help. Give me a little more info.
Harry Holida - are you asking about style (solid off square - old old style [my 50+ year old tiller has this]) or newer (aka Eurocardan -triple lemon- quoted from Ted of Everything Attachments)? But take in account there are also different "grades" for different implements.
Hope that helps
The series is what size the PTO size is for what size the brush hog is for example most likely a 5 foot brush hog will use a series 4, bigger goes higher!😇🤠🇺🇸
Couldn't you just take the guard off. Then put a wedge at the mating end of the outside shaft and hit the wedge with a hammer or small sledge hammer until it moves. Then put the cover back on. That's the way I do it, but mine didn't come with a guard.
my wife never says my shaft is too short
ABC ABC, it’s nice of her not to bring it up, you have a good wife.
What joke. Take it to a dealer get in the shop and get the hammers and torch and pentrating oil . Main thing grease the two half's so they don't rust and store with pto in a upper position so water cannot run down into the two parts if stored outside .
