- Wondering how to change PTO shafts, or if you even have a dual speed unit on your tractor? This video explains the process. It also applies to White tractor models such as the 2-85, 2-105 and others.
All you videos are great and informative. Keep up the good work
Very helpful. Thank you.
You're welcome!
Good info! People ask this question fairly regularly so thanks for documenting it! Are the stub shafts the same on the 50 series and 55 series? I cut 1" off my 540 stub shaft so I could run it at 1000 for smaller stuff and just idle the engine down more. Used an optical tach to find 540 on the shaft and a marker on the tractor tachometer to mark where 540 is at. PTO Shield? Never heard of her! lol! I just picked up an 1855 and he gave me the PTO shield and I was like "what is this thing!???" lol. Took me a second, but I remembered they're supposed to have a shield lol! Thanks for the video!
Yes, the shafts are interchangeable between 50 and 55 series. 1650/55 shafts are their own animal, but they will interchange with an American series shaft. There's no shifter on those, so I'm not sure if it justifies a video.
Thanks I just rebuilt my pyo in my 2 85 and was wondering why it would go into 1000 in 540 lol it was machined down lol
That's better than the whack some guys would give the shaft to shear the pin off
can i leave the 540 shaft in and change to 1000 rpm? i have a 1000 rpm rotary mower and can not seem to find an over run coupler and would like to have an over run coupler to prevent tearing up pto clutch from the centrifugal force of mower when when shutting down, seems these clutches are available for 540 and not 1000. i would just put a 540 yoke on pto shaft and mow. thanks for any input
There is a pin that drops when you're in 1000 that prevents the 540 shaft from going in all the way, at least when it's all working right. A lot of farmers "did things" to make it happen so yours might possibly be "modified" by now.
@@ThatOliverGuyChris how would i go about removing the pin?
@@jimkurk5575 It's internal, so you'd have to remove the pto unit to get it out. I have a video on rebuilding these units that shows the pin. Of course, I don't recommend removing it, because there's liability in that.
@@ThatOliverGuyChris i understand where you are coming from, thanks for reply
@@jimkurk5575 i also dont recommend shortening the 540 shaft until it's the same length as the 1000.
Another good informative video. Think you’d ever film your 4-225?
I haven't yet, but can do that in the near future. Thanks.
Uploading a video for you right now.
Chris Losey thank ya sir
Thanks, I have to do this for my neighbor. No, I'm not Amish Haha.
Hi Chris, you helped me out with the over/under in this tractor the other day. Now I’m digging into it I see my pto has a snap ring I’m familiar with behind the bolts you’re taking out. It doesn’t seem to have the shifter. This is a 67 1850. Is it a switchable pto or just 540?
If it doesn't have the shifter, then it is a single speed unit. There will be a plug driven in the hole to keep the oil in, but no shift rail or bolt.
You’re a good man. Thanks again for the expertise

Mine won't come out, is the bearing stuck in the pto housing? You made it look so easy.
Sometimes they can be hard to get out. I've been thinking of taking an old pto shaft and making s slide hammer out of it. Hook it up and slide the hammer to get it out.
@@ThatOliverGuyChris OK, so nothing should be holding it back besides rust?
@@jwdozer8524 correct.
I'm going to check my 1755 it be nice to use it for 1000 work
How is it for the 1800a series ? Cause we got one that is leaking oil !!
Where is it leaking
@@ThatOliverGuyChris around the shaft out the bottom
Watch this video, at 10 seconds I pull the shaft support housing off the main PTO housing. ua-cam.com/video/jkglNaGbm8g/v-deo.html
The one on your 1800 looks a little different, but comes off the same way. Underneath is a round cover held on by 4 bolts just like in my video. You'll want to drain the rear end down before you remove it. There are shims behind it, so don't lose/wreck them. Remove the 4 bolts and pry that round cover out of the PTO housing and you'll find a seal in the back of that cover. That is most likely your leak.
@@ThatOliverGuyChris Will do, Thanks !!
