I checked the main drive clutch and it is 150. So it looks like the next step is to split the ol girl and see what is wrong inside. Thanks for the info. If anyone has a good John Deere Tech manual for a 4440 I'd be willing to buy it. I'm looking for one.
I checked the hyd pressure on the PTO clutch as it started slipping. And it is 104. My understanding is it should be 145-180 max. I don't know where to adjust it. Can someone help me out?
