    Posted by Del R on 18th Jul 2019

    I bought my mower in 2005 and use every year to cut lilly pads in front of my boat house. Best investment i ever made.

    Works like promised.

    Posted by Gary L. Black on 6th Jun 2015

    We have an area in our pond with lots of water lilies and were looking for a eco-friendly way to get rid of them. The mower worked well for cutting the lilies but it takes to people in the boat. One to run the trolling motor and one in front with the mower to keep weeds from wrapping around the arm after they're cut.

    Performs as Advertised

    Posted by JB on 11th May 2015

    I am using the cutter for about two acres of "water shield". So far it has performed reliably and set up was fairly easy. A couple comments: it is awkward and heavy. Attached to front of Jon boat and pushed forward. In thick weeds would have one person keeping weeds from building up on cutter arm (drag issue), and if you are paddling - have at least two doing it in thick weeds.
