see manual for PTO clutch adjustment
thanks, for some reason it started working but I'm going go thru it anyway to make sure its right. and the brake/clutch is acting up also. going to download the link you sent and print it. your help is greatly appreciated!!! I hate to admit this but you may get a good laugh at my expense. after it engaged yesterday I decided to take it for a spin, not looking at the height adjustment I just drove into yard and things went bad, height adjuster dropped to 1". I wont have to mow that spot for several weeks! and it looks like crap!
