Good Evening All! I am retired now and at age 60 I finally bought a decent lawn mower instead of $999.00 new plastic and tin. What I bought is a used Grasshopper Zero turn mower 61" deck. I mow under a half acre and this does it very fast! But it has a couple problems. First is rust, mostly on the outside of the deck. The dealer wanted about $19 for a 6 oz. spray can of touch up paint. So my first question is what spray can paint might match the brown and the tan on the mower? Or does anyone have a paint code #? Second is the engine governor doesn't work. Kohler CH20. I know how to adjust them by opening the throttle all the way and turning the gov shaft counterclockwise all the way and tighten up locking bolt. Or is this engine different than all the other engines I have worked on? Thanks in advance for your help! Steve
