My 149 and 169 have the same problem. If you adjust the linkage enough to disengage the pto you wouldnt have the proper gap when you engage the pto and it would rapidly wear the pto button. So what i did was to adjust the proper clearence with it engaged and then when you pull the lever back drop in a homemade wedge. Keeps it tight in the disengaged position.Its a 2 handed operation to kick it in and out but it will get you by till you can get it repaired. I have been running them like this all summer. And they have worked great. Hopefully over the winter i can get one of these apart and figure out how to repair.
