I just bought Gravely ZTR 52 inch cut, 23 H.P Kawasaki, when I get in a little high grass the engine wants to (bog) slow way down, like it needs more power, can I adjust anything on the engine to fix this problem. I have a mulch kit on it also.
Not trying to be a jerk, but you could drive a bit slower or overlap a little more. It sounds like it is only a sometimes problem and any time you up HP in an engine, you decrease durability. Perhaps not a good idea in the long run.
