i own a new exmark metro hp 36" walkbehind with the 15 horse kaw. it is a great machine and love it to death. but latley i have noticed that when i cut bermuda grass it will leave a little trail of uncut grass next to the rear right tire all the way down the lawn. kind of hard to describe but looks like a mohawk left on the lawn. i will post a pic of it sometime soon. i have overlapped the mower on each path to try to compensate for this problem but still does it. i thought maybe the tire was pushing the grass down and the blade wasn't cutting it and when the grass stands up straight again, then you notice it because it is longer than the rest of the lawn. any help would be great!!!!
