Description
Cut Lake Weeds Directly From Your Boat
The Aquatic Mower gives you a wide, controlled cutting path through unwanted aquatic vegetation without relying only on manual shoreline tools.
This battery-powered weed cutter mounts to your boat and reaches up to 5 feet below the water. Its lightweight frame, adjustable mount, and reciprocating blade system help you maintain swimming areas, fishing lanes, boat paths, and waterfront access points.

The battery and power source are not included with the Aquatic Mower. Purchase a compatible 12-volt battery locally before operation.

Maintain Cutting Performance With Less Blade Maintenance
The Aquatic Mower uses self-sharpening sickle-style cutter teeth. The reciprocating upper and lower blades move against each other to slice through submerged vegetation.
This design reduces the need for frequent manual sharpening and supports dependable cutting throughout the season.
- 15 upper cutter blades
- 16 lower cutter blades
- 4-foot-wide cutting assembly
- Compact pin-and-channel drive

Built for Consistent Underwater Cutting
The 1/4 HP oil-cooled motor provides steady cutting power while operating from a 12-volt battery.
The sealed electric system provides a practical alternative to gas-powered equipment. Low power consumption supports longer cutting sessions without fuel storage, exhaust, or engine maintenance.
- 1/4 HP electric motor
- 12-volt DC operation
- Durable steel drive shaft
- Low-maintenance power system

Cut Up to 5 Feet Below the Surface
Adjust the cutting position based on your boat, water depth, and vegetation. The 4-foot cutter bar helps you cover more area during each pass.
Mechanical cutting lets you choose where vegetation gets removed. Open selected swimming areas, fishing lanes, navigation paths, and shoreline access points while leaving other vegetation in place.
- Maximum cutting depth of 5 feet
- 4-foot cutting width
- Upper depth-adjustment collar
- Safety switch with fail-safe control

Add the Deck Mount Bracket for Select Boats and Pontoons
The optional Deck Mount Bracket provides a secure mounting point for applications where a lower-profile installation or closer mounting position is preferred.
This mounting option works well for select boat and pontoon deck configurations. Review your boat layout before selecting the bracket.
- Lower-profile mounting position
- Stable connection to compatible decks
- Designed for select boats and pontoons
- Available as an optional product selection
Built for Controlled Waterfront Maintenance
Durable materials, adjustable controls, and battery-powered operation help you manage thick aquatic vegetation from your boat.
12-Volt DC Power
Operates from a locally purchased 12-volt battery without gasoline.
1/4 HP Motor

Aluminum and steel components include a marine powder-coated finish.
Adjustable Mount
Set the cutting angle and depth for different boats and water conditions.
Fail-Safe Control
A safety switch provides direct control over mower operation.
Make Your Waterfront Easier to Use
Target the aquatic vegetation interfering with boating, swimming, fishing, and shoreline access.
Reduce Manual Cutting
Cover a wider area from your boat than most handheld weed cutters.
Open Boat Paths
Cut navigation lanes and reduce weeds tangling around your boat motor.
Target Selected Areas
Remove vegetation from problem areas while leaving other sections intact.
Improve Fishing Access
Clear casting lanes and travel paths through dense aquatic vegetation.
Battery-Powered Operation
Operate without gas, fuel storage, engine exhaust, or pull-starting.
Manage Seasonal Growth
Repeat cutting as needed when aquatic vegetation returns during the season.
Collect cut vegetation with a lake rake or collection tool when practical. Removing clippings keeps floating weeds away from docks and swimming areas.

Lake Mower
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.
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
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.
