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!

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.
