Angles of the Jenson Lake Mower™

"To anyone who has had to endure the labor intensive battle of vegetation around your boat dock, the Jenson Lake Mower™ is like a gift from heaven. Now, for no more than one hour of my time per month I am able to keep my seventy-foot dock clear of growth. Actually, I now look forward to this task - it's fun."
Samuel C. Jones, Star Lake, MN

"I cut 3 acres in 10 hours with the Lake Mower™. Everybody on the lake is just so pleased with their machine."
Vic Hannon, Camden, S.C.

"...We are on a small bay which was being overtaken by non-native lilies which someone planted several years ago. Your mower is helping us to keep them from totally destroying our bay and perhaps get it back to the quality it used to be."
