Then tried a 3.25" pulley which was good but a too fast for fluffy snow so I went to this 3.4" now and 90% throttle with light snow is perfect! And if it's wet heavy stuff then I'll give her wide open throttle. I found if you run it too fast with light fluffy stuff you end up wearing it all! So I just adjust the throttle according to how wet the snow is. Your results may vary but two years worth of tinkering has led me to this setup.
So I reread and realized Macman covered it very well.
Probably a dead horse thread by now. But I will post this final info just cuz.
Here are the rotor speeds of his changes very much like my MTD experience. I did this because I also have an h48 with a larger rotor and needed some math to change it with.

Thrower Pulley=2.5, Rotor=2498RPM, MPH=89.2
Thrower Pulley=3.25, Rotor=1494RPM, MPH=53.3
Thrower Pulley=3.4, Rotor=1428RPM, MPH=51
Thrower Pulley=4, Rotor=1214RPM, MPH=43.3
Thrower Pulley=4.5, Rotor=1079RPM, MPH=38.5

I will be changing the drive sprocket. To avoid a smallish pulley. Plus I already have the 4 inch lower. (18 tooth drive sprocket.)
Thrower Pulley=4, Rotor=1434RPM, MPH=51.2

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.
