I recently paid 18k for a 2wd 4850 with 5100hrs on it. Took it to a local tractor mechanic and found metal shavings in the transmission oil but the tractor still seems to shift fine. He thinks it would be around 10k plus labor to fix it. Would like some opinions on whether I should fix and keep the tractor or if I should get rid of it.

Change the filters and change the oil, how big of shavings..
It would be the breaks out of adjustment or dragging.. Honestly I don't think you need to fix it till you have a problem..
The shavings will not likely cause you shifting problems, unless your talking a big pile of metal..
Just keep the oil clean and your clutch packs will love you.
We looked into this with our 4955, there are very common issues with these tractors.. I think there was one other possible problem I just don't remember

Ive got 8 4850 and every 500 hours I change the trans and hyd filters. I find metal shaving in there all the time, this started when they had around 4000 hrs on them, They have now got between 13000 hrs and 18000 hrs never touch them and still going strong

The PTO slowly spins without it being engadged and the lever doesn't like to stay up either. Wen I bought it the park brake is all disconnected and the transmission sensor was unplugged. Thinkinthe guy who owned it before did a lot of n#&#r rigin.

It is somewhat normal to find some fine metal shavings in oil and filters. Do you have inboard wet brakes? A lot of times, as they wear they produce some metal shavings, especially if worn down when there might be more metal shavings. Spending on the type, metal rivets shave off.....consult someone who is a JD specialist. 50 series JD are pretty much bulletproof. I own two 50 series JD's and basic service is all they need. One has over 10000 hrs and one over 8000hrs.

When the clutch is burnt out the disks warp then they will cause drag when disengaged. Same would be if one of your transmission clutch packs were burnt tractor would creep ahead in neutral. Likely your detent on the PTO engagement valve spool is worn why lever won't stay up.
