How to remove a stuck PTO shaft on a JD 475

My neighbor is going to give his daughter and son-in-law his 475 and wanted me to spruce it up some. It isn't too bad but the rear PTO coupler will move back and forth but the splined portion will not come off. Do any of you have a pet method for removing this? I went online and there is a guy who unbolts the deck end and then removes the deck to get to the stuck collar. That didn't look too bad but I was wondering if there might be a better way. On the old couplers, they would lock open if they were turned once pulled back. But this model does not have that feature. I guess JD saved $5 by omitting that feature. Any hints? Thanks

Re: How to remove a stuck PTO shaft on a JD 475

The deck can slide forward enough for driveshaft to come apart, then you have more room to work on peice stuck on tractor. I bought a rebuilt kit for my ole X485, worked sweet after that

Hit it with chemicals. PB Blaster is my personal favorite. Let it soak in for a few, and tap it with a hammer. That helps the chems penetrate better. It's likely just dirty/crusty.

This is what I'd try first. There is a floating ball that sits in a depression between the collar and PTO stub, locking the shaft in place. When the collar is retracted it allows the ball to come out of the depression so the shaft can be slid off the stub. Most likely, the ball is frozen to the stub and won't release the shaft.

Get the coupler lubed and it will probably twist and lock too.

Re: How to remove a stuck PTO shaft on a JD 475

I jacked the front of the tractor up and tried to pull the deck free but it would not come off. I was afraid that I might be doing something wrong. I'll give it another try. I'm sure it's just a lube issue but getting to it is a bear with the deck in place! I can see why JD went to the belt drive on later models. It is way easier than this method especially for someone with a bad back!.

Re: How to remove a stuck PTO shaft on a JD 475

Man, I'm learning a lot with this mower! Number one my neighbor isn't the best person to take care of his mower. Two, I found out that this shaft has a set screw in it to prevent it from separating from the other half. Three, I got the deck out by taking the gearbox end loose from the shaft and then I could slide the deck out. I have learned a trick from working on these old JD's and that is to use carb or brake cleaner instead of a penetrant. I sprayed the hell out of it and it finally came off. I took it apart and cleaned all of the balls and holes and then regreased it. Put it back together and it works really well now. The sleeve will stay locked open once it is removed from the shaft and will not reset until it is pushed onto the PTO shaft. Oh boy, that was just getting the deck off! I am not looking forward to the rest.

JD did not go back to belts on later models. High end models use shaft drive, the x4X5 series is now the x7XX series.

Carefully back it up onto ramps and then slide under with creeper between rear wheels (for future readers).

Re: How to remove a stuck PTO shaft on a JD 475

Now I need to remove the instrument cluster and it looks bad. Has anyone removed an X475 cluster an easy way? It looks like the wheel has to come off and then the whole tunnel screen. How about the brake and cruise control handles?

Re: How to remove a stuck PTO shaft on a JD 475

I see your point Zebra, but I sort of wanted this to be about the X475 rather than a specific problem. As I progress with the rehab, I will probably have other questions about it. One thing I had forgotten since I owned an X475 is how big they are. They are like a 455 but seem even larger. I was surprised when I started to buff out the hood only to find that JD used black plastic and then painted it! I'll have to paint it now. Have any of you painted over the plastic used on this model? I'd love to hear from you about what primer you used and the prep.

Your title is problem specific, that's why I suggested starting new thread.

PB Blaster, Liquid Wrench, and some force should get it loose. Let the penetrating agents sit for a while.
