Default 782 hi pitch whine

I have a 782 with a KT17 II that has developed an intermittent high pitch whine. I changed the Hy-Tran fluid and filter about 12 months and 30 hours ago. The whine happens more at lower RPM’s than high. I can’t tell if it’s coming from the drive shaft or the trans. My thoughts are drive shaft. This whine is more apparent when not moving. I have the neutral adjusted correctly and the whine happens with the break off as well. This whine is distantly different from the normal hyrdo growl/whine.

Any thoughts/ideas?

Chris

My wife has what I would call the same whine, when I went to change her fluid and filter the whine became more... No, wait... I may be thinking of something else.

LOL. My wife's is more like a bark than a whine.

I had a chance to look at the tractor and the drive shaft has no play. I changed the engine oil/filter, sharped the blades and installed the mower deck. I noticed that the PTO was making some noise when not engaged and no PTO belt on. Turning the PTO on stopped the noise. After installing the deck and belt, the PTO noise went away. Also, the whine I mentioned above would go away when the PTO was turned on.

Would it indicate a bad PTO bearing?

Thought you said it was a tranny whine.
Yes, a bad bearing could make it whine.

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.
