Battery & Motor

The LawnMaster CLMF4015K electric mower is powered by a 40V 4.0Ah lithium-ion battery that delivers up to 50 minutes of continuous runtime when fully charged. Lithium-ion batteries have become the preferred battery type for cordless electric lawn mowers thanks to their lightweight, compact size and ability to hold a charge longer.

The included battery requires 2.5-3 hours for a full charge. It uses a fast charging system that brings the battery up to about 80% in the first 1.5 hours before tapering off. This helps reduce overall charge times.

The mower's brushed motor provides adequate power for residential mowing applications. At 40V, it falls on the lower end of voltages for cordless electric mowers but is sufficient for cutting grass up to 4-inches high. Higher voltage mowers around 60V tend to have more torque for handling thick, dense grass.

The battery and motor combine to deliver gas-like power that makes quick work of small- to medium-sized lawns. Run times up to 50 minutes allow mowing up to a quarter acre on a single charge. Those with larger yards may need to invest in a second battery or opt for a higher voltage model.

Maneuverability

The LawnMaster CLMF4015K is very easy to maneuver thanks to its lightweight and wheel design. Weighing only 38 pounds, it is one of the lightest electric mowers available. This makes it easy to push and turn without excessive effort.

The rear wheels are 7 inches in diameter and the front wheels are 5.5 inches. This wheel size provides smooth rolling motion and stability. The mower can make tight 20 inch radius turns around landscaping beds or trees. The compact size and tight turning radius make the LawnMaster ideal for smaller yards.

The single lever height adjustment is convenient and allows you to change cutting height from 1.25 to 3.75 inches in six adjustable positions. It is easy to push the lever and adjust height for the type of grass and conditions.

Overall, the lightweight build and smooth rolling wheels provide excellent maneuverability. The LawnMaster CLMF4015K is very easy to use and allows effortless mowing even in tight spaces or around obstacles.

Noise Level

The LawnMaster CLMF4015K 15-inch electric mower operates at under 70dB(A) according to the manufacturer. This is significantly quieter than a typical gas mower which can be as loud as 95dB(A). Electric mowers like the LawnMaster provide a much quieter mowing experience by avoiding the noise created by gas engines.

The quiet operation of this cordless electric mower makes it a great option for early morning or evening mowing sessions when you don't want to disturb neighbors. You'll be able to have a conversation while mowing without needing to raise your voice. Birds and other wildlife are also less likely to be scared away by the mower noise compared to a gas mower.

With its quiet brushless motor, the LawnMaster CLMF4015K allows you to enjoy mowing your lawn without creating an annoyance for those around you. The quiet operation is a major advantage this electric mower has over traditional gas-powered options.

Safety Features

The LawnMaster CLMF4015K comes equipped with several important safety features to prevent injuries while operating the mower.

• The blade can be stopped immediately using the prominent red stop button. This emergency stop switch disables the mower blade, preventing it from spinning until restarted by the user.

• There are protective guards around the sharp blade and any areas that could come in contact with the user's hands or feet during operation. The blade housing covers the top and sides to prevent accidental contact.

• A lockout requires the operator to hold down a switch while pushing the start button. Releasing this switch will automatically power down the mower. This two-step process helps prevent unintentional starting.

• The handle includes an easy-access disable switch to turn off the mower without needing to reach the stop button. This allows quick shut off from the normal operating position.

These integrated safety mechanisms give users important control over the spinning blade while requiring intentional operation. The emergency stop and disable switches make it fast and simple to halt the blade when needed. The protective guards provide an extra barrier around hazardous areas. Together these features minimize the risk of injury from the spinning blade or other moving parts on the LawnMaster mower.

Grass Clippings

The LawnMaster CLMF4015K offers versatile options when it comes to dealing with grass clippings after mowing your lawn. This mower has a 15-inch cutting deck that allows you to either mulch, bag, or side discharge the clippings.

Mulching

The mulching capability uses the mower's blade to chop up grass clippings into tiny pieces and blow them down into the lawn. This returns nutrients back into the soil so you don't have to bag or rake. To activate the mulching function, simply close the rear discharge opening.

Bagging

If you prefer to collect the grass clippings, this mower comes with a 14.5 gallon nylon grass collection bag. When bagging is enabled, the clippings get sucked up and collected in the bag so you can dispose of them. The bag is easy to attach, remove, and empty as needed.

Side Discharge

You can also side discharge the clippings out of the right side opening for continuous cutting if you don't want to mulch or collect them. This ejects the clippings out to the side as you mow. Just make sure the mulching plug and bag attachment are removed when side discharging.

Overall, the versatile clipping options allow you to choose the right method for your lawn care needs. Mulching returns nutrients to the lawn while bagging and side discharge allow removal of the clippings.

Maintenance

Keeping your LawnMaster electric mower running smoothly involves some regular care and maintenance. Here are a few key areas to focus on:

Cleaning - It's important to remove clippings, dirt and debris from the mower deck after each use. Allow the mower to cool first, then use a garden hose or air compressor to spray out the deck. Make sure the underside is clean and clear of buildup.

Blade Sharpening/Replacement - The mower blades should be inspected regularly for any nicks or dullness. Using a dull blade will lead to ragged, uneven cutting. Sharpen the blades with a file or replace them entirely if badly worn. Blades should be balanced and tightened properly after sharpening.

Storage - When storing the mower for extended periods, first clean it thoroughly and allow to fully dry. Remove the battery and store it in a cool, dry place, avoiding temperature extremes. An occasional recharge over winter will keep the battery fresh. Store the mower upright in a clean, dry area. Avoid laying it flat, which can lead to fluid leaks or damage.
