Last night I was mowing waterways with my 4440 and a Woods MD384 mower (7ft). Things were working fine for about an hour or so, then the slip clutch on the mower seemed like it gave out and I couldn't hardly keep the mower going at all. I tried it in A1 and it still would not keep going. I'm pretty sure this is the mower - I will tear into it tonight. Could the tractor PTO be part of the problem? I can't think that would have been enough of a load to hurt the tractor? I did not hit anything, jut is tall grass and weeds. Can I just tighten the slip clutch and try the mower again, or is there more to it than that?

If mower driveshaft continues to spin but mower stops cutting grass then slip clutch needs adjusting a little tighter.
Like he said, tighten the slip clutch. I try to slip mine a little at the beginning of the season to ensure that it will slip as designed to protect the driveshafts. I put a sharpie mark across the clutches and loosen them, turn on the pto for just a couple seconds, and then look at the mark to make sure the clutches moved. I use a 15ft batwing behind the 4440 in some pretty tall stuff at times so no you didnt hurt the tractor. I seriously doubt any seven ft mower has the component strength to damage a 130hp pto. That said, if you dont have the slip clutches adjusted proper (ie too tight), they will not act as the circuit breaker they are intended to be and you could easily grenade that mower with that much hp.
