So far so I'm pretty pleased. I have a couple of questions though... It's a 25hp Kohler and it backfires just about every time I shut it down. I read the Kawis do this alot. Is this unusual for Kohler? Is it just a break in thing that will get better? The hydrolics seem to me to be pretty noisy... forwards, backwards...always hear 'em working. Much more pronounced than my previous Gravely ZTR. Normal? Last job of the day my customer comes out so I drive over and shut the machine off. Chit-chat a bit... show off the new machine. I go to start up the mower... Nothing! Just a very faint click. Ask the customer for a hammer, tap on the starter and it started... thank God! What's up with that? Break in thing again?
