Broke the new Deere

[CobyRupert]

Couple questions:
Was it really out of 4wd? Why did it pop on asphalt at road speed if in 2wd with zero torque?
How come it didn’t keep flopping around when front wheels turned?

yes it was out of 4wd, i havent used 4wd but a couple times this past winter and once this spring - there is an idiot light for it and it was not on. notable is this, the 4wd has been VERY hard to get into gear as well as the rear differential lock i have commented on it here before, it was so hard to get in/out of 4wd my wife/daughter could not even do it.

the reason it wasnt flopping around was because it slid off the splines i presume or busted the pinion shaft i havent looked at which end is busted off, the drive shaft was laying on top of the mower deck so was not turning around anywhere it was disconnected from everything and it made zero noise after the loud pop

i had work the rocks to scoop is why i kept using it, if it wasnt leaking oil so i wasnt concerned do to the lack of noise - 99% of the time you are going to hear some kind of a noise but it sounded normal and still does

You keep saying 'drive shaft', but your description sounds more like the mid-PTO shaft to the MMM. That would not affect forward or reverse motion, but could be a result of something else.

This could be one of those times when you get it back and find that it works as well as it was supposed to, instead of the way that it used to.
Good luck.

Well, one end broke free first, then the shaft banged around a bit between the deck and the tractor until the other end broke free. It would help to know which end of the shaft did the damage to the deck because that would be the one that broke first. You have a weird one there...tell the shop guys everything you can remember or give them a note. good luck

Some pics would be nice.. Sounds like the u-joint failed. The shaft had to be turning fast.

Does the front lock up for 4WD or does the transfer case lock up for 4WD on these tractors?..

 

[searcyfarms]

correct its the output shaft from the trannie ( drive shaft ) whatever u want to call it that runs to the front end
I have pix i just went out and took them, will have them shortly they are uploading to my email then i can put them on here and you can name/call them whatever you want i call them broken ;-)

i can assure you the 4wd was not engaged, i have had many and still have 4wd vehicles/tractors in my lifetime and grew up on a farm and still have one - when i made the 90 degree turn from my gravel drive onto the asphalt with the loader on if i had forgotten to take it out of 4wd i would have been abruptly reminded when i turned the front wheels for those of you that are not familiar with that sensation
