Hi everyone, I was hoping someone may be able to help me figure out whats going on with my mower. The mower runs perfectly up until I engage the blades when the blades are engaged the engine will bog down once in a while and then run perfectly again when the blades are off. I know the issue has nothing to do with a locked up spindle or pulley because it will to the same thing with the belt off (so no extra load on the engine). I've jumped the seat safty switch (very quickly) to see if that changed anything and it didn't, so I am thinking that it has to be either the PTO switch it self or possibly a wire that is shorting out somewhere. Something else I should add is that I sprayed some WD-40 into the clutch anywhere I could (I know that probably wasn't the best idea but I had to try something so I could mow) with out removing it and it seems to have helped the issue a bit so maybe it could br a locked up bearing in the clutch. Any ideas would be greatly appreciated. Thanks in advanced!
