Jenson Lake Mower Features

The Lake Mower™ is built to last, comes with a two-year warranty, and will give you years of service. Many of the first models ever built are still in service today, over two decades later. This weed-cutting machine makes it easy to control lake weeds (commonly referred to as algae or seaweed) affecting your waterfront at an affordable price. Unlike water chemical treatment or huge, expensive harvesters, the Lake Mower™ gives you the ability to cut and trim the areas you choose and leave the rest.

Jenson Lake Rake™ Features

The Jenson Rake™ can be used to easily push or drag floating debris to shore. It mounts onto your boat just like the Jenson Lake Mower*trade;, and has its own Mounting Bracket included.

Once it’s attached to your boat, you can use the Jenson Rake™ to either PUSH or PULL debris, depending on how you prefer to set it up. We have also recently added extra holes through which to arrange the tines at a 90 degree angle, for even more customized options.

The Depth Stop, installed right above the Bracket, carries the weight of the Jenson Rake™. The Rake Handle has two sides with flat surfaces so that it won’t rotate inside the Bracket when there is uneven pressure on it as you gather vegetation.

As with all of our products, the Jenson Rake™ has a one-year warranty and can be returned within 30 days for a refund if you are not completely satisfied. We want happy customers!

  • Lightweight
  • 5 Feet Wide
  • Aluminum & Stainless Steel Construction

  • Disassembles for Compact Storage
  • 2 Year Warranty
