So my grandpa's (now my dad's) older John Deere lawn tractor just roasted the sealed unit transaxle, by pulling a lawn roller.

Dealer says $2k after install with new pulleys and belts.

The tractor would then be worth $700.

Are there people fixing sealed transaxles? I will know the alpha-numeric soup that is the model by tonight.

Thanks

Sounds like a k46. Very weak rears that john deere and many others have been using for a while. Its said that some models of mower exceed the max weight for it, from the factory. 

There is ways to fix them and change the oil, but it will probably happen again. You can find a better machine with much better rearend for cheaper than 700$. 

Research the tuff-torq k46. Its probably what this machine has

Seems like a lot of these lil guys benefit from a fluid flush and fill, and failing that a reasonably handy guy can order a reman for under $500 and slide it under there.

I wouldn't pay the Deere dealer a nickle.  Lawn mowers are not complicated devices.

I rebuilt mine three years ago for $400.  The kit includes new pumps and a third magnet to catch more debris.  It was pretty easy work on, but I can tell it's already lost some torque.  How JD didn't get sued over this I do not know.  I'll never buy another JD product.

Its a LT155 and probably 15 years old.

Funny thing, my dad already bought a x724 Ultimate with all wheel steer.

There is a video online to rebuild these as Apis mentioned.

You can change the fluid in these and it does help. You have to remove the transaxle and drain from the top. I put  synthetic 0w-50 oil in it and went 800 hours on mine. That included plowing snow and cutting. Changed about every 100 hrs. Of course this is more of a preventive measure and won’t help the OP now. 

This Tran axles is used in just about every inexpensive lawn tractor so you might find a low hr mower that some dope never checked the oil and blew the motor. Check FB market place
