The PTO on my Gravely is slipping. I checked and verified the free play at least 3 times. It has a good 0.5 inch of free play and I checked it from both the lever side and then again from the transmission side to make certain there was nothing binding or dragging. I also set the tractor on a level spot to verify the oil level in the transmission was not low or high. The oil level was correct. When I engage the PTO, it is slow to come up to speed and sometimes it does not. Also, when I hit high grass, it slows or stops completely but the engine RPM does not change. I am now pretty sure the PTO clutch needs replaced. Any thoughts or advice? I know that means the engine comes off and the transmission split. This has to be expensive. Any cost guesstimates? Thanks in advance.

Wish I new something of Gravely units so I could help.

I guess this is more of a :bump: than anything else, hope you get an answer soon.

I dont know anything about Gravely but it sounds like you have a mechanically actuated clutch and the friction disks for the clutch are non existent or glazed over
