Cub Cadet 782 Hydro Leak
Hello to all! I’ve been enjoying my 782, but when I park it, it leaks hytran on the floor. The leak ranges from small to mid size. I just figured I would go ahead and fix it. From the pictures it is obviously been leaking and is all over. There appears to be no leaking on the top of the pump, or the trunnion seals. It appears to be lower on the machine. I know the cork gaskets are notorious for leaking.
The question I have is should I remove the fenders and clean the pump up really good, so that I have a good idea and view? And then put a piece of cardboard on the bottom to try and find where dripping is coming from? Also, it it okay to use a little bit of baby powder to see where the leaking is running? I’m in high school, and I wouldn’t get to this project until next week, but I want to be ready! Thanks for the help as always! IMG_1317.jpg IMG_1318.jpg IMG_1319.jpg

If you have to ask, you'll never know. If you know, you need only ask.
You are pretty much on the right track to cleaning up the mess best you can and using baby powder to locate the source of leak. It may very well be the cork gasket but then it could be something else. When cleaning, pay attention to "wet" buildup of dirt and grass. Most of what I see in your pictures appears dry except on the bottom. Good Luck.

That’s what it appears to be to me, but I’ll have to get the fenders off to take a look and clean up. I know they are common to fail and leak. Thank you, I’ll take a look!

Definitely easier to do the job when everything is clean. Take the pan off, clean everything thoroughly, after its dry use white spray on foot powder to find the obvious leaks. Some may not show unless it's running and some may just "sweat" but your drip just show up pretty quick.

Those rag joints don't look too good. You may want to look into replacing them and check your couplers for any wear. I bet the ball bushings are gone and check that front input seal too if you tear into it.

Looks like a restoration job might be in order. Clean it, tear it all apart, learn everything about it, paint it, put it all back together and enjoy it! Then on to the next one...
I remember taking so many things apart when I was a kid. That's the time of your life when you learn things best. Go for it kid!! We'll all help you along the way here with the onlycubcadets.com forum.

Best wishes for the Holidays!!

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.
