45 inch snowblower parts help
I tore up the brass drive gear for my snow blower this winter. I am using the CUb Cadet part number listed on the cub cadet site for my snow blower. The part number is 717-1425 or 917-1425. When you look up this number it comes up as a gear for a 33" snowblower. I have ordered two of these so far based on the Cub Cadet part number and the problem that I keep having is that I have a 1/4 keyway in my gear and the two that have come in so far have a 5/16 key-way. Either Cub Cadet has the wrong part number or maybe they changed the key-way over the years. I believe mine is the 451 blower not the 551 based on there being a gasket in the gear box. My sticker listing what actual model it is, is missing the numbers off the sticker. Regardless, the gear is listed as the same gear for both of them.

Good point, I'll have to take some when I get home. I guess I could post that I have an 1863 tractor it is on.

As far as which one you have, it doesn't matter for that part.
While the original number of that gear was 717-0300 for the 450 thrower, it was Superseded to 917-1425 so that's not the issue as far as I can tell from the numbers and diagram from Parts Tree. All 3 throwers use the 917-1425 gear. So my guess and this is only a guess, you don't have any of those 3 throwers, or Cub Cadet had a major Boo, Boo?  I have looked at quite a bit of these throwers last year, and did purchase 2 different ones. I have a 450 and a 451. Visually those 2 are the same, except for the gearing. The 450 is geared for the 4.5" PTO and the 451 is geared for the 6" PTO The 551 is geared for the 6" PTO and the shute/auger opening is 2 inches taller that the 450/451 (450/451 approx 18" tall and 551 approx 20" tall). Also if it's a 551 the auger is not centered in the housing. It sits at the lower/bottom of the housing, with a gap at the top because it's taller. The 551 also has an end of the shute angle lever on it. And all 551 throwers are yellow from the factory. Is your I.D. tag missing? As mentioned, pics would be a big help.

#1: mill a 5/16" keyway in the shaft. #2: mill a "step key" ----1/4" for the shaft, and 5/16" for the gear. The step key would prolly be easier, unless your keyway in the shaft is "wallered out" as they say in the "holler"-- then mill to 5/16" in the shaft. #3: you could purchase a "updated" 5/16 keyway shaft,if all other dimentions are the same. If I have to explain this further, you would not understand.

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.
