Cub 123, The new factory Cub Cadet ISO mounts for the IH Cub Cadet Quiet Line series are in fact very different from the original mounts that were on these true IH Cub Cadet garden tractors. The new mounts are very easy to install, as the lower mounts now actually rest through the cradle, and rise a little above the cradle. The upper mount will cap the lower, and fit together nicely.
I have made a few adjustments to mine, those preformed was only snugging the new mounts down a tad. I'm probably about 3 threads above the lock nut. I have also installed new flex disc at both front and rear locations. My Quiet Line runs very smooth and quiet. Though, the sheet steel is not perfect and straight, but close,...mine will still rattle those a little.
In my opinion, the QL is the nicest looking garden tractor IH Cub Cadet ever made!
105 Tom, 1 out of the three Ql's I own had the grenade gears in the engine. This was in my other Quiet Line 1450 with Kohler K321aqs engine.
Here is my garden tractor.
