Default Anyone ever speed up a 48" IH deck?

Ever since i cut my lawn with a 782/50c i was so amazed with how well the lawn looked when i was done that ive been searching for a way to speed up the 48. Ive seen a lot of guys speed up the 44/50" decks but what about the IH 48 with cast nose? i always heard the older cub decks spin slower then other colored decks so, i did a blade tip speed check with a laser tach. I wound up with 3560 RPM at the blades tip which matched exactly to the engine RPM on the 127. (i guess that's what cub was aiming for). is there a pulley out there that i can get to speed these blades up?

There is a speed up pulley that went in the center of the deck- IE the one that accepts the belt from the engine and also drives the belt for the other two blades. IMO I've used both the 50" deck and a 48" and while the 50" throws grass farther the 48" cuts better because (I think) it's taller. I prefer the 48" triangle cast iron center decks.

There is no speed up pulley for the triangle decks.


Nice to see you again Ken!

well shoot, looks like im going to have to make my own. ill try getting an OEM center pulley and split it and see if i cant mate up a smaller one on the top section. anyone know the size the "speed up" pulleys are for the 44" decks? i think that would be a go size to start with.

Just so we are all on the same page here, you want to speed up a cast nose "triangle" deck. Is that correct?

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.
