Broke the new Deere

[sd455dan]

No word yet? My bet is the rear u-joint worked forward, fell off, and since the shaft spins with the front wheels, it caught in the mower, stopped the front wheels until the input shaft snapped. Then you were home free except for missing FWD. that痴 why your drive shaft looks like a pretzel. Should be no problem at the rear unless the splines on the shaft show wear. Replace the front pinion, driveshaft, repair mower drive, and away you go.

That sounds plausible to, It would have been telling to see how tightly the front pinion splined shaft is clamped and also how far into the female end the splined piece of pinion actually is.

After looking at the pics again , It does appear the driveline may have been almost all the way forward and snapped the pinion almost flush with the diff housing and almost flush with the end of the clamp.

But I still have a problem with a missing cap. I guess it is possible the u joint hit with enough force once the driveline was free of the rear splines to have impacted hard enough to knock a cap out.

they just called and asked if they could deliver it after their driver gets back from lunch - replaced front pinion shaft/ring gear matched set, set gear lash, replaced drive shaft, replaced two deck pulleys and brackets that were bent by driveshaft coming off, replaced engine oil/filter ( i had purchased that when new and sent with driver/hauler ) for its first oil change. They didn't charge me for the oil/filter change ;-) they also changed the oil in the front diff obviously since they had to tear it down. No noises observed, no whines, no clunks, no grinds, no squeals, diagnosis seems to be same that the ujoint either failed or not installed right and came apart resulting in the shaft coming loose from the rear drive shaft. The splines were not damaged to any degree on the transmission shaft and the new driveshaft slid on fine so it did not need replaced. I will watch for any leaks/noises.

i suppose its possible it could have whacked something on the deck and slung the cap off, when i get it back here in a bit i will check the deck and see if there are any significant marks on it it looked like the pulleys/brackets took the brunt of things.

mowed with it for about 20 mins, seems fine no unusual noises or anything

Awesome. Very lucky.

Still don't understand the engine laboring and whine just beforre destruction.

Maybe you should road it to your neighbors and back?

Run it down to the neighbors at full speed and back a time or two, get over the PTSD you have making that trip.. Remember to buckle up for safety. Glad you got it fixed.
