Have some pto problems I hope someone can help.I was blowing heavy wet snow today with my 448,and several times I had to stop and clean the snow out as the clutch slipped a little,then suddenly stop working alltogether.I believe it is an ez adjust.I loosened the 1/2 locknut on the clutch and turned the big nut in maybe a turn and it got tight and the engine turns if I try and turn the big nut in any further.Am I adjusting this properly,it's been a while since I've done it.It still has no bite at all and it looks like there is lots of clutch thickness there,maybe 1/4".I put a new clutch disc in several years ago and have had no problems till today.Thanks.
