Default 1450 Cracked Aluminum Muffler Support
I wanted to know how imperative it is to either fix or replace this aluminum piece if it is cracked. I don’t have a good used one, but I did purchase a steel muffler brace that is supposed to keep this from happening.

What do you guys do to repair these, or should I just replace it? If I was to install that brace, could I just leave this cracked one on?

Fix it if you want, it will prolly crack again. In your second picture, that bolt. I removed mine and drilled a through hole, added the muffler crutch, added a backing plate (on the coil side) and then through bolted it all.

How would you fix it? I was thinking of drilling 2 small holes at each end of the cracks, grooving them out a little with a dremel, and then filling all cracks and holes with jb weld.

Find someone who can weld it for you. You can also have them weld a backup plate where that top bolt is.

finding someone that will weld aluminum around here hasn't proved to be easy or reasonable. I've got something else I wanted welded.

The tin on my 1450 had been welded years ago and the aluminum air duct was cracked at most of the welds when I took it apart in 2018. I fabricated some small angle iron reinforcement for the areas that needed a threaded hole and used rivets to hold the new angle iron in place on the air duct. Used sheet metal patches and rivets to bridge some of the other cracks. I think installing a muffler support bracket will help quite a bit. It's not pretty, but it is holding together.

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.
