Default 680 PTO update

I was at my girlfriends yesterday trying to finish up what i wasnt able to the other day after the issue i was haveing. So first i messed with some wires, then i unhooked the PTO wire and turned it on, no problems. SO i hooked up the wire again, then turned it on with the wire hooked up, still on the concrete pad in front of their garage. Again no problems. SO i figured it had to be a wire grounding out. Started mowing again and i started mowing on the sand mound to finish their yard. It was mowing fine until I got the bottom side of it and then as soon as I got turned to mow acrost the mound, thats when the tractor started runnign rough again leading to further beleive that its a wire somwhere. So I checked the wires didnt see anything susicious. Im still puzzled. But if it is the pto, i found one online for 256.95.http://www.psep.biz/store/cub_cadet_...pto_clutch.htm
This is the site i found it on. PN# CC917-3044, or Warner 5209-41. Has anybody used this site before? Thanks in advance.

I have a mower that was doing the same thing. Under minimal load, it seemed to work fine, but when I engaged the PTO, it would bog down and never recover. Long story short, check your spark plugs. A rusty or corroded plug will give these symptoms, and it's a cheaper guess than a new PTO. Just my $0.02.

Good luck!

Nate

The PTO likely isn't bad from what you are describing. You haven't found the problem yet.

Does the problem occur on flat ground, on a slope, or both? I'm wondering if this could be a fuel problem...

Matt, that's what I was starting to think. It only happens on slops not on the flats. I havent done anything to the fuel system other than putting some marvel mystery in it. I regapped the spark plug too at the same time.

That engine should have a fuel pump because the bottom 1/3 of the tank or so is below the carb. The symptoms you are experiencing sound like a failing fuel pump to me.

This is probably kinda a dumb question, but is there any way to test it to see how well it's pumping? I'm gonna be looking at it again today so if there is a way to test it I'll do that today.

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.
