I re-did the mounts in my 1250 Nightmare, using the current style genuine Cub Cadet motor mount. I have been well satisfied with the results.
One of the things that you need to consider when using these mounts is that the torque specification of 100 inch-pounds is a bit tight and will crush the mount. Some say that using the standard length bolt recommended along with a lock nut showing about one and half to two threads is the correct torque. I found neither to be correct. What I did find is that the correct tension is found after the mounts 'wear in' for awhile and the the mounts are a bit broken into the weight of the engine. Somewhere in the middle worked the best for me, after tightening and loosening several times to find what seems to be the best for my tractor. It is a process of adjustment, but well worth the exercise, IMHO.
I know the Cub Cadet mounts are expensive. However, it seems to me that using the intended part for the purpose is far more preferable than re-purposing a part from another application and expecting favorable results.
