Angry Cub Cadet 70 mower belt problem
I have a 70 (#385058r1) w/mower (#473425r1). Can't keep a drive belt on it. Alignment looks good, pulleys look straight,& run free. Still keeps throwing the belt. Anyone have an idea?

First, welcome to OCC.

The information on the tractor is good. However, the mower deck information is not valid.

Back in that day, the mower decks available were the 38" and 42". The size is determined by the cutting width. In addition to that, there were 4 generations of those decks. A picture would be most helpful.

"Generally speaking" situations like yours is a result of using aftermarket instead of Cub Cadet belts. So....are you using genuine CC belts..???

You need a 3/8" wide belt. When I got my 100 from my dad and 149 from my brother they both said they were having problems keeping the PTO belts on them. They were both trying to use "A" width belts which are close to 1/2" wide. I picked up the correct 3/8" belts from the Cub Cadet dealer and have been mowing with the 100 for 4-5 yrs and have never had the belt jump off.

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.
