782 won't go
I have a 782 (new to me). When I push the hydro lever to forward .... nothing. Pull to reverse... nothing.
Another time I started it and pushed it all the way forward and it went (pretty fast, not slowest speed). Then another time I pushed all the way forward, it paused a few seconds, then made a screeching sound and took off. Pulled the fender and the hydro linkage appears to be working as it should. The trunion is not worn at all (first one I have had that didn't have the trunion worn). I took the tunnel cover off the the drive shaft is spinning. While the fenders were off I pulled the top off the rear end and its plenty of hydro fluid (not horribly dirty). Lift doesn't work either. Could a filter clog and do this? (filter looks old). I do have a spare hydro, but wasn't planning on using it for this one (just gave one away as well, dang, maybe should have kept it). A bad hydro seems to be a rare occurrence. Whats next to try?? (Filter I know but I don't have one, maybe time to go get some....) But most likely the experts here will sort it out quickly.

Me thinks your issue is an air leak draining hydro fluid out of the lines. Is why after some time your tractor shoots off after you engage the hydro.

Change the Hydro Fluid and Filter.

An air leak is a new one - an air leak where?

Here is a long shot to check out but worth checking. Make sure the rear pin is good on the flex coupler to the hydro shaft. If a pin shears off the drive shaft will be turning but the hydro may not at times and may turn at times.

While you have the rear end opened up, here is a real good opportunity to clean it up. Get a new cover gasket and then install you new Hydro Fluid and Hydro Filter.

I agree with the guy above-sounds like a driveshaft pin wore through or broke.

Im guessing fluid and filter as well. Had a 129 that would do this as well as randomly stop moving and it had a clogged filter

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.
