Hello , I have been in business for a year now but have only recently started mowing nicer lawns. I have an Exmark and in Bermuda grass I leave uneven lines and ridges ( which makes my cut look like garbage) and I am unsure of how low to mow without giving a scalped look. Any help would be appreciated. Also are there any time saving techniques that anyone knows of ? Not looking to cheat the customers of quality, just looking to save a little time. Thanks for any help or suggestions. Sorry for the long first post.
