4WD does not engage, Branson 5220R

That's easier to fix than having to replace the entire diff gears. Those bolts pretty much act as a mechanical fuse.

Time to go easier on that front axle and not hang the entire weight of the tractor on it while pushing/pulling hard.

This happened to my 4520R about 4 years ago.
Same problem again this week. *sigh*

How did you get to it

Found the problem, the differential in the front Axle had the bolts stripped off the ring gear. Now to figure what parts are current and where to get them. If anyone of you have a hot tip, I'd appreciate it. Thanks Jim

How did you get it out

The broken bolts? I haven't had that happening to me.

But it requires pulling half of the axle out, to pull the broken bolts out and to pull the broken section out of the diff carrier. Should be doable with the axle in place.

I recommend that you pull the loader out to have more room and so you're not working under the loader.

Do you know how to get it all out to fix the bolts?
