How Fast Can I Mow?
You can mow approximately 1 acre every 3 hours. The time spent will depend on the type and density of the weeds, your boat motor, etc. We suggest cutting at a slow, steady pace to prevent any serious damage in the event you encounter an obstacle. Several of our customers use two Lake Mowers, one on each side of the boat, to cut a wider area in one pass.
How Often Do I Need To Mow?
Our customers report mowing 2 to 4 times per season. The rate of regrowth depends on the type of aquatic weeds, the temperature, the depth at which one is able to cut, etc. We’ve had some customers tell us their lily pads didn’t regrow at all after having kept them under the surface for a season!
How Do I Remove The Weeds Once I Have Cut Them?
It is important that the cuttings are removed from the water. Not only is it unsightly to leave them there, but large volumes of decomposing plant material can adversely affect the ecology. Additionally, certain plants, such as Eurasian Milfoil, can propagate from the fragments.
The cuttings are typically raked to shore, where they can be removed via nets or pitchforks. Since 2007 we have offered the 5′-wide boat-mounted Jenson Rake for purchase. This rake allows your boat to easily push the weeds to shore, saving time and energy!
Once on shore, the cuttings will shrink as they dry. Some aquatic weeds make excellent compost for gardens and flowerbeds!
Would I Need A Permit To Cut My Aquatic Weeds?
There are areas and specific weeds that require permits – too numerous for us to keep track of. Please check with your state DNR, the EPA, city or county officials, or local water authority before buying. In Texas, aquatic weeds fall under the Texas Parks and Wildlife Department, and one needs to submit a treatment proposal two weeks before cutting.
Could I Buy An Extender If I Needed One?
If you need to cut deeper than 3 feet, you can order either a 2-foot or a 4-foot extender at any time. The extender simply fits between the cutter head and the vertical drive shaft, and connects with 4 dog point setscrews at each end.
Will I Need To Order Additional Spare Parts?
Your Lake Mower will come with extra fuses, setscrews, and an Allen wrench (hex key) necessary for assembly. Occasionally our customers will drop a small part in the water. We recommend that assembly is always performed on land. However, if you should need a replacement part for any reason, simply call us and we can ship the part to you immediately. Due to the nature of cutting underwater, there is the potential of running into something solid, such as a rock, log, or man-made debris. If this should occur, the mounting bracket for the Lake Mower has been designed to break in such a way to prevent the Lake Mower from falling into the water and to prevent damage to your boat. Mounting brackets can be ordered complete or just the affected parts. Some of our customers prefer to purchase a spare mounting bracket to have on hand in the event that they need it.
The blades are extremely tough, self-sharpening agricultural blades that never need replacement.
What Type Of Battery Would I Need, And How Long Could I Operate The Lake Mower Before Needing To Recharge It?
You will need a 12V deep cycle marine battery (typically 100Ah or 120Ah), separate from the one your boat motor might be using. On a full charge, the HD5000 will run for approximately 7 hours. The RG2500 will run for approximately 10 hours. Keep in mind that you will need to recharge your battery. A helpful website to visit to learn more about different batteries and what they are suited for is Lifeline Batteries. There is a tab for Marine Batteries at the top, and you can select it to read an introduction to marine batteries, features, a comparison between different kinds of batteries, etc.
Can The Lake Mower Be Used In Salt Water?
Yes, one of our customers has successfully been using the Lake Mower commercially in saltwater for years.
