Default Loose PTO Belt for Walk Behind (CC 760 ES)

Hi,
I bought a used cc 760 ES Walk Behind Club Cadet Lawn Mower (Model 12AE764N056) last year mid-mowing-season and the PTO belt was shot. I replaced it with the OEM part (#954-04139). It worked fine but it was so loose that when I engaged the PTO the blades took a while to get up to speed and in high grass they easily got bogged down and slowed.
It is spring and I want to fix it. The cables seem to be in good shape; no rust or fraying. They seem to be tensioned OK; when I engage them, the brake immediately comes off the drive spindle.

Is there a fix to this problem? Is there a smaller belt I should be using? Any ideas would be greatly appreciated.

Ben

PS: I think I attached some pictures.

Could the blades be slipping on the spindles??
Ive seen those square/star doodads on the bottom of the spindle shaft worn down to where they didn't grip the blade very good.
Just a thought.

@Ironman, Good idea. I replaced them last year and inspected the spindle shafts and they are in near perfect shape, so that is not the culprit.

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.
