On the 1872 I am working on all of the rear end mounting holes were wallowed out especially the front support bracket holes. They were slotted from wear about 1/4 inch. If that is the case the rear could be rotated enough to miss align the two shafts and cause excessive wear on the couplers. Might be something to check.
Everything bolts up to the rear end housing. Even if it fell out of the frame, all the shafts would still be in place, and in the same alignment they were in. The front driveshaft, is the only spinning shaft that would be affected....

You are correct. For some reason I was thinking that the PTO was attached to the three point mount. I think I would still check the alignment in case the bearing support is not machined correctly. Too bad that the bearing support will not accept a self aligning bearing. I guess I am out of ideas.

I finally got the pictures that were imprisoned in my camera uploaded. They show the culprit of what was causing the extended driveline noise and clattering. As you can see in the first picture the constant torque pulses from the engine are just hammering everything apart.

It's worse on a diesel for sure, but the whole rear PTO setup was a very poor design. Deere actually did a much better job on their rear PTO (318 for example).

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
