Normally wheel bolts working loose but not taking half shaft too. Sounds expensive not to mention could be dangerous for those involved.

Now Then..
What model tractor?? There's a screw holding the final drive reduction gears on the inner end of the halfshaft, I've seen them break or come loose, however that was cured 30 years ago by a wire clip to prevent the shaft coming out
The other possibility is that the inner bearing has failed.. :-(

A lad not too far away had a 6620 do it a couple of years ago now.

It happened to me on a 6930. Can't remember cause exactly but it was a shock at the time. Luckily wasn't on the road

Bolt that holds shaft in Broke ?

Happened a 6910 of ours one time ploughing , it was the inner bearing . Was got fairly quickly so no harm but if it happened on the road with an inexperienced driver it could have been a very different story

Do you have a photo of it
There is a locking tab with the bolt on end off the half shaft will have broke when you rebuild it make sure the locking tab is fitted properly heard of a dealer sending a tractor back out after repair 50mtrs down field with fert spreader on the wheel and half shaft came off again

6830!!! Happened last night with 12t of tatties on traveling flat out on main road

Ouch! Poor man has no luck! Wonder if those big floatations he runs in spring weakened something? Much damage?

Ive had a customers final drive break the same way. He backed into a silage pit and nudged his duel on the side of it. His words nugded, but I dont know

I have a picture somewhere of a Massey with a failed half shaft which spends a fair bit of time on wide floatations on. Once we repaired it we noticed the other half shaft has started to crack

Well as it is a 6830 they have no spring clip to hold inner bearing on the half shaft. There are two scenarios I can think of that will allow half shaft to move.
1. (Most likely - inner bearing has collapsed, a common fault on early 30 series particularly 50K models), this would allow half shaft to move enough to break the bolt holding half shaft.
2. The bolt has unwound due to a missing or broken locking tab.

This is a 40k, if the bolt has broke what's the worst scenario I presume it will have minced up planetary gears ect

Well unlikely to have mashed the planetary gears due to the fact they are more a less contained in the housing. If bearing has collapsed then filings will have likely filled the bearings on planetary gears, taken chips out of some of the gears, damaged friction brake disk along with piston and pressure plate. This is all worst case tho!
