Cub Cadet 127 bolt ID help

[finsruskw]

Should be a 3/8 x 1" if it is an engine mount bolt
There are/should be 4 of them.

Be advised...if one or more are missing...
DO NOT use bolts that are TOO long!!

I'll bet they ALL, or what's left of them, are loose and one came out.
The front 2 are up directly above the front axle and you will have to raise the front off the ground to access them. Check and verify they are still there and tight,

Be a good time to remove the wheels as well to inspect and repack the bearings and lube the axle pivot as well

All 4 of the engine mount bolts are there. The bolt is about 1” 3/4.

[finsruskw]

Does the bolt have IH stamped on the end?
If so, it is an original bolt.

[crazykilik]

Here it is.

[finsruskw]

Check the front section of the transmission housing.
There are 8 bolts that hold it together,
4 of which are 2" long with the others being either 1-1/4 or 1-1/2, all 3/8" bolts.

First thing I noticed was that the bolt is worn under the head. Hood bolt? Axel carrier bolt? A bolt that wiggled out from being lost long ago? I don't recognize the bolt head monogram.

It is a Grade 5 bolt. Buy locally and cut to length (if need be). To me, it looks like one of the six bolts that the frame secures the rear end assembly. This is a typical problem with Cub Cadets.

Hmm, well the good news is I’m now familiar with every nook and cranny of my tractor. I feel like I maybe chasing a ghost. Another item to note, I changed the transmission fluid a few days prior to the vibration starting. I used super tech heavy duty tractor hydraulic and transmission fluid/Stens 120-265 transmission filter. I have no maintenance history on the tractor. It came with a old house. The fluid that came out looked descent. No goopy mess or metal flakes.
