I have been using my Exmark for about 5 months. I have gotten a good grasp on all the handling of the machine, but I can't figure out how to prevent the tear marks on the turkf when turning. I have been using my own lawn as a test field so to speak. I know the weight is a major factor, but there must be a secret to NOT tearing up the turf. Any and all info and tips would greatly be appeciated.
