I bought the TT oil but haven't done the swap. I'm having a very hard time thinking that is going to be a magic cure. Would seem like a bandaid on something that needs stitches. Was going to use the TT oil after the rebuild (if I can source a kit).I confess I didn't quite follow the parking brake comment. I get tying it, and checking if it will spin a tire, but that was while flooring the pedal.
I'm not sure how you check the parking brake, as it relates to this.
Also, in the other thread, I think you had mentioned that you were going to get the different (higher viscosity) transmission fluid. Did that change anything?
I ask because with your model number I am able to see that a new OEM K72b is $1,556 with free shipping through hydrodrives. If it turns out you need to rebuild maybe purchasing new will give you better piece of mind. Judging by the condition of your X500 it would be worth the money to do the swap because you cannot replace that tractor for similar money.
Hadn't you said that the weak tranny started after the recent oil change though? That would make me think it's at least worth trying a fluid change.I bought the TT oil but haven't done the swap.

Tying it to a tree is easy enough, but seems exactly like what happens when it goes uphill. Tires don't spin it just dies. But am home all day so will try that later.
Yeah, same reason I learned to work on things mechanical.... I simply couldn't afford to pay someone else to do it. Sure, I made some mistakes, and had to re-do a few jobs, but, in the end, it just made me more mindful of what I was doing.Many years ago I used to be afraid of doing any serious repairs on different engines. I saw that as a personal failing, so I just started studying and working on them. I can't tell you how many quality repairs I've done over many years. In my case I just had to do it because going to someone else (Dealers) frightens me even more..LOL And at the prices they are charging today...OMG
Never did a rebuild, but have had a couple of them apart several times. They're not overly difficult to get apart and get back together. Be careful with the fittings for the external hydro lines, they have to pass through the case and thread into the pump on the bottom of the case, there's several o-rings on these and if you nick one it'll leak. This pump is separate from what drives the tranny, but connected to the same input shaft, so it stays connected to everything as you take it apart.Has anyone actually done the rebuild on a K72? Just curious if there are any significant pitfalls that are different than the videos I've watched with the k46 and k61(?).
Just talked to Tuff Torq, they have the kit for my particular unit listed as on backorder, but the guy told me that just means it'll be about a 10-14 day delay to ship it, so yes it's available... There is also a place in my home state called Mulligans Parts Co. that lists it in stock, though I've never heard of them and there isn't a lot of reviews etc.. The latter is a bit cheaper.if you find that rebuild kits are available let us know! I'd like to have one in stock!
triple checked. and just checked one more time. At first I was pretty convinced that the fluid change was a factor, but I think that it was just a spurious coincidence.@davescarp Have you made double triple sure that the freewheeling lever is all the way in? It could be that the bypass valve is not fully seated closed. My friend's x570 seemed to have a little catch in it before it was totally in. Give the rod a good firm push.
It just seems really freaky that it goes from working to not after an oil change.
