The LawnMaster CLMF4817E is a corded electric lawn mower from Avani. It has a 48V lithium-ion battery system with fast 1.5 hour charger, brushless motor, and 17" cutting deck.

This model claims to be easy to use with its lightweight 43 pound body, adjustable cutting height, and single button start up. It's designed for quiet, clean, and eco-friendly lawn mowing on yards up to 1⁄4 acre.

Some key features are its foldable T-handle frame, rear bagging system, mulching or side discharge capability, and a 2-year limited warranty.

Design & Build Quality

The LawnMaster electric mower has a solid and robust design constructed primarily from thick steel and quality plastics that feel durable.

The steel deck seems sturdy enough to withstand general wear-and-tear from mowing season after season. The thick plastic handle, battery compartment, and wheels also appear like they will hold up well over time.

There are no flimsy parts that give the impression they might break easily. The materials and construction seem on par with other major battery-powered lawn mowers in this price range.

Overall, the build quality makes the mower seem reliable for regular home use and you wouldn't have to worry about things falling apart after a year or two of mowing your lawn with it.

Cutting Deck

The LawnMaster CLMF4817E features a 17 inch cutting deck made from durable steel. This deck size is suitable for small to medium sized lawns up to 1/3 acre.

The generous 17 inch cutting width makes efficient cuts and allows you to mow more grass in fewer passes. This saves time and keeps your lawn looking tidy.

The deck has 7 height adjustments from 1.5 to 4.5 inches, which suits the needs of various grass types and seasonal conditions. Raising the deck for taller grass helps prevent bogging, while a lower setting provides a closer trim on manicured lawns. Adjusting the height takes seconds thanks to a simple lever control.

The compact footprint allows you to maneuver easily around landscaping, trees and flower beds. It's also slim enough to access tight spaces. With its lightweight design, the LawnMaster can navigate gentle slopes. The steel deck resists dents and tends to wash under itself while mowing damp grass to help avoid clumping.

Motor & Battery

The LawnMaster CLMF4817E has a powerful 48-volt brushless electric motor that delivers efficient and quiet performance. Electric motors have several advantages over gas engines - they produce no emissions, require less maintenance, and operate more quietly.

The included 4.0Ah lithium-ion battery is lightweight and provides up to 45 minutes of continuous runtime when fully charged. That should allow you to mow up to 1/4 acre on a single charge. The battery features overload protection and cell balancing to maximize efficiency and battery life. It's easy to remove from the mower for off-season storage or charging.

A fast 60-minute battery charger is included which allows you to recharge the battery conveniently when needed. An LED indicator lets you check charging status.

One downside is that runtime is a bit shorter compared to some higher-end electric and gas mowers. However, for small to mid sized yards, the LawnMaster should provide enough cutting time to get the job done. Extra batteries can be purchased separately to extend cutting time for larger properties.

Features

The LawnMaster CLMF4817E has many great features that make using electric mowers easier and easier. Key features include: Self-propel system: The CLMF4817E has a variable speed rear-wheel drive motor that allows you to select your desired pace thanks to the speed select dial. This makes it extremely easy to self-propel the mower up inclines or across longer distances without having to put in a lot of manual pushing effort.
Mulching capability: The deck has twin blades along with a specialized mulching plug that helps cut and recut grass clippings so they are much smaller and easily biodegradable when put back into the lawn as natural fertilizer. You can engage and disengage the mulching plug as needed for different jobs.
48-Volt battery: The CLMF4817E has a lithium-ion battery pack that provides up to 60 minutes of runtime with the self-propel engaged or 75 minutes without self-propel. Runtime can vary based on factors like grass conditions, height, and more. The 48V battery enables the mower to deliver plenty of power while running.
Brushless motor: A high-efficiency, low maintenance brushless motor powers the blades. It provides excellent torque and efficiency. LED headlights: Allows for evening mowing and better visibility when working in shaded areas of the lawn. Quick folding handles: The handles can be folded easily for compact storage. Battery level indicator: Lets you monitor the battery charge level visually while working.

Ease of Use

The overall ease of use of the LawnMaster electric mower is quite good. The controls are simple and intuitive with a key start ignition, speed control knob, and single lever to adjust the height of cut. This streamlined control design allows you to get set up and mowing fast without fussing with complex controls. The mower's lightweight design and rear wheels make it easy to push and maneuver, allowing you to cut shapes and trim grass with good handling and precision. It rolls smoothly over uneven terrain and does not take much effort to push or turn even in thick, taller grass.

The mower is also relatively quiet, operating at an average level of about 75 decibels. This creates a friendly user experience and reduces noise pollution. While not totally silent, it is quiet enough for early morning or evening mowing without disturbing neighboring homes or apartment dwellers too much.

The compact size and foldable handlebar make for easy transport and storage, which adds to the overall ease of use of the LawnMaster mower. Simply fold down the handlebar and roll the unit into place when not in use. The light weight also makes it easy to move around by hand or throw in the car, so you can use it in many different environments with no hassle.

Overall, the streamlined and intuitive controls, lightweight easy maneuverability and lower noise output, give the LawnMaster mower a very good rating for ease of use for homeowners and lawn care enthusiasts alike.

Maintenance

The LawnMaster electric mower requires very little maintenance compared to gas-powered models. The brushless motor has no spark plugs, air filters or oil to change. Maintenance mainly consists of keeping the mower housing clear of grass clippings and debris that could impede cutting performance.

The polymer deck design also resists rust and corrosion so it retains its appearance over time with minimal care needed. The blade should be periodically sharpened or replaced as needed to maintain clean cuts.

Replacement parts like blades and wheels are readily available from LawnMaster or online retailers. And with no routine tune-ups or oil changes needed, maintenance costs are greatly reduced over the lifetime of this mower.

Overall the minimal maintenance of electric mowers like this LawnMaster model is a major advantage over traditional gas mowers. Just keeping the deck clear of debris and periodically servicing the blade is all that's required.

Safety

The LawnMaster electric lawn mower is designed with safety in mind. It is CPSC certified, meaning it meets the safety guidelines set by the U.S. Consumer Product Safety Commission.

While it does not have an automatic shut off feature if the handle is released, there are several safety mechanisms built in. The blade must be disengaged before the mower can be pushed backward or pulled by the handle. The power button must be depressed for 2 seconds before the mower will turn on, which helps prevent accidental start up. There is also a key lockout to prevent unauthorized use by children.

Additionally, all electric components are sealed to prevent water damage or electric shock if you accidentally mow through a puddle. The deck design also minimizes the chances debris will fly out, a concern with some electric or gas mowers.

The wide tread tires and rear drive design provide a stable platform and good traction so you are unlikely to lose control of the mower while operating it.
