Thanks for all the ideas! I didn't realize I was gonna start such an argument. I have some greased lightning that I'm gonna use sparingly. As all this is in the engine area. I'm gonna take the engine cowl off and anything else I can remove and clean away from the machine. I particularly want to make sure the trans axle coolers are clean. Thanks for the suggestion of A/C cleaner. I don't recall who suggested it, but thanks just the same. As for pressure washing. I don't want to force water where it doesn't belong, but using a hose (without a nozzle) doesn't seem like a problem. Thanks Rivets. I know what I'm gonna be doing tomorrow before I mow!
that is what happens on open forums and it is good that people get to express their opinions in a civalised way so don't feel bad about it.
It is your mower so ultimately you will have to decide what you will do and now you are equipted with all the accumulated knowledge that the forum can provide.
