John Deere 6200 drive shaft failed

[Chris16]

Hi there, I’m looking to buy a nice tidy John Deere 6200, with 4,000 genuine hours, I’ve been informed the drive shaft from the engine snapped completely while running a feeder wagon, it’s had a main dealer repair and seems all sound, will this of done any other internal strain or damage? My current 6200 has 11,000 hours and has never done this, any advice would be appreciated, many thanks

Did they change the damper unit in the flywheel when it was repaired? That could have been the reason the drive shaft failed.

Thanks for the reply, I will find out tomorrow,I was wondering if it had been over taxed perhaps on a machine to big. Just don’t want to buy it then it end up beiing a can of worms sort of thing, thanks again

I've a 6400 on some 10k hours, and never touched the damper or the drive shaft, did a power quad repair some years ago, and the uj's appeared sound with no play. As the 6200 shares the same drive components as the 6400, it should be fine,mine was dynod at 139hp !

Typically find that those drive line couplings fail from to low an idle rpm, I like to adjust linkage to where the idle rpm is high enough to smooth out chatter and vibration.
The Waterloo small frame 7000s were famous for driveline issues, easily fixed by using the 7810 transmission coupling and a little machining for a longer mating surface on the trans input shaft stub

Thanks for the replies guys, so probably just one of those things and nothing to worry about! Think il get it bought, thanks

That’s not a lot of hours if genuine for a twenty year old tractor do you know the dealer that repaired it

 

[Chris16]

Hi, yes I do, it’s genuine, the shaft snapped clean in half apparently, but was switched off instantly, just making me wonder if anything internal with pto etc would be damaged due to excessive load perhaps, I know a few of these tractors with big hours that have worked hard and never had this trouble

Quite common for these things to go boom. If you are unlucky they'll wreck the end of the transmission. But I think that is from the 20 series onwards as the valvecover is on the front as opposed to the underside, might be wrong.
If everything functions correctly there is no cause for concern. If the exploding drive shaft screwed something up it should be quite obvious.

Thanks, we’ve had a really good inspection and test now and couldn’t fault it, i think our offers been accepted, so fingers crossed!
