The clutch engagement lever on my 1986 220 will not stay engaged. It pops back just as the mower engages tall grass. Now I first thought that the clutch may be out of adjustment but it is not slipping at all and it checks out. My next area to look is the actual engagement arm on the clutch. The manual says to check this with a straight edge. My question is, is this something that commonly just goes bad? Does anyone have any tricks or steps that may make this work that the manual doesnt suggest. Im sure I am not the first person this has happened to.
The only other thing I can think of is that the cam assemblies are just worn out. Im headed outside now to do a visual inspection. Hopefully I can make something happen here before the mosquitoes comes out

My first thought would be the cam assemblies but I don't know a whole lot about the clutches accept how to adjust them.


When I engage mine it definitely feels like it pops in to a certain degree and takes a little bit of force to pop it out.

I adjusted the clutch a little bit and I can now get it to stay but its still feels way to easy to go in. I know how it is supposed to feel. If I adjust the nut to wear I can engage the lever then the fan will be loose on the shaft. The small nut will be as tight as I can get it and it just bottoms out. The drive clutch didnt get much use since this engine came out of a 600 series tractor. Its funny how this all started after I put those Meg Mo blades on.

If the fan nut is bottoming out then you probably are missing some parts in the assembly or the large spring washers no longer have any "spring". You should also examine the fingers on the clutch fork that fit between the cams for wear or damage.
