My front axle upgrade.
Back in 1980, I got my first Cub Cadet, a used 86 upgraded with a K321 engine.
After a season of mowing, I took off the mower, and before I installed the push blade for winter, I was enjoying a few "wheelies" around the yard. Crack!! The front axle snapped.  The PO had run too short of a mower drive belt and severely notched the front axle. Well my dealer had a new front axle on the shelf!! Several years later I decided to upgrade to 1" spindles. During the axle replacement I had learned of how important it was to keep the front spindle bolts tight, so I decided to make some modifications to the new spindles. D7K_1144640x533.jpg I tack welded on 1/2" collars to the top and bottom. I then got longer Grade 8 fine thread 1/2" bolts and double nuts. After the modifications, this tractor mowed 3 acres of rough terrain grass for 15 years with no visible wear to any of the parts. I put this axle in a QL 1000 today.

So if the objective is to keep the bolts tight, I can see why you went with longer bolts and double nuts, but what was the purpose of the 1/2" collars?

Quote:
That front axle is famous for having the bushing in the axle stop turning, then the steering friction wears out the hole in the spindle. Plus it helped distribute the clamping force of the bolt on the bushing, further insuring the bushing turned when I neglected to grease it!!

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.
