Boomer47 front tires locked up

DLTrekkers,
Why don't you read the whole thread before you start throwing out baseless insults? Like, try reading Post #7, maybe?

When I worked for a MF dealer we were cautioned to properly counter weight a tractor when a loader was installed They explained the front axle can be damaged when the loader is used because the rear wheels do very little driving and the front axle gets overloaded trying to pull the tractor.
A front axle without diff lock will spin one forward, one reverse this is normal due to the differential. If one wheel is locked the the input pinion should spin when turning the free wheel. Turning the input (pinion) shaft will turn one or both wheels but remember the input shaft turns many times to turn the wheels once, so you may have to watch closely at both wheels again due to the differential only one or both may turn.
If it does not function as above believe you have pinion bearing out because the pinion should not have any end or side play, so it appears the bearings are out in the pinion allowing the pinion to get out of mesh with the ring gear.
Hoping it isn't so cause that will hurt the pocket---badly!

Ouch! That's not what I was thinking it looked like.

This is what I was expecting it to look like. My LS P7010C axle is similar, just 2 as big. Takes about 4 gallons of gear oil to service.

Actually, I don't like the feeling imparted by the tires when in FWA when turning at all. That grab and release feeling I don't like. Actually, about the only time I use mine is when I'm cutting hay on one field I have that has a pretty steep swale on it and only to keep the tractor and disc machine from crabbing sideways. and... I don't believe I've ever engaged the rear locker or the front. My units have both front and rear lockers.

My last comment (after reading and rereading the thread is), take it to an authorized NH tractor dealer and let their trained technicians repair it.

I see (after Lou) posted the diagram that it's much more complex than say my Kubota front end.

Some of the New Holland CUT's had an auto engage clutch for the FWA.

With my WM75 if you step on the brakes it goes into 4WD.

LS P7010C and JD 6420 will too. Have to jump on them fairly firm, actuated by the brake light switch. Assist in braking. With MFWD engaged, both axles are tied together, the rear brakes then also brake the front wheels.

My boomer 40 was tooling along one day and their was a little bang and I swore I saw a front tire lock for a second, I stopped, then started and it was ok. A few months later I was loading stuff and it went bang again and locked up, I unloaded the bucket put it in 2wd and it was still locked, I rolled backwards and it moved so I slowly go to the trailer and took it home. Then I tested it there and bang it locked. I opened the bottom left drive gear on the bottom of the wheel and lots of metal from a bearing fell out, and some of the balls were split, by the gears.
I replaced the bearing and seals and reshimmed it all and it has been fine for a few years now.

Yep, I bet thats what happened to mine. We used to keep a bush hog on the back then I did a project where it was too tight to have it, and the bucket was full of boulders, hundreds of times, and driven hundreds of feet
Bearing 9 had broken and the balls fell into the gear and got shredded by 26
