Broke shaft from transmission

Certainly gets torque, but maybe not "added" torque.
And certainly isn't "running free", or the tractor would function ok without the shaft at all... as I see it.

Pretty standard response from a dealer.. "Never saw that before". And we know it isn't true, or he/she is pretty wet yet behind the ears.

Failing U-joints caused vibrations that flexed the input shaft until it fatigued and failed. New u-joints many hours ago when they started to fail would have been cheaper.

Very likely ^^^

I would add that you need to grease this shaft just like any other driveline and from threads I have read one of the zerks is a little inconvenient to get to.

Totally agree with you...Negligence on my part

yup....they are a pain to get to...The front joint is the bigger pain as there is a solid plate connecting both sides of the frame...Kinda need to take the shaft off to grease the sob!!

I think regardless of the brand,all the driveshafts are a royal pain to grease.On my Kubota GR which has 3 shafts,there are no zerks on the joints.The manual says to squirt oil on them which seems rather odd to me.

First I hear of that!!! what is the oil gonna do? just spin around and splatter all around?
