Description
Motorized Underwater Weed Cutter
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.

12-Volt Battery Required
The battery and power source are not included with the Aquatic Mower. Purchase a compatible 12-volt battery locally before operation.
Recommended Cleanup Step
Collect cut vegetation with a lake rake or collection tool when practical. Removing clippings keeps floating weeds away from docks and swimming areas.
How It Cuts
Self-Sharpening Blade System
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


Oil-Cooled Electric Motor
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
Wide and Adjustable Coverage
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

Mounting & Setup
Mount the Aquatic Mower to Your Boat
The standard Aquatic Mower uses an adjustable aluminum transom mount. An optional Deck Mount Bracket is available for select boats and pontoons where a lower-profile or closer mounting position is preferred.
Standard Adjustable Transom Mount
Set the cutting angle and depth based on your boat, water depth, and vegetation. The adjustable mount is designed to support boat-mounted underwater cutting without permanently fixing the mower to one cutting position.
Install a compatible 12-volt battery, confirm the mower is securely mounted, set the desired cutting depth, and make sure the safety control is accessible to the operator.

Optional Mounting Upgrade
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

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.
