While the average run time of 30 to 40 minutes per battery charge is a bit low compared to other similar models, this electric, cordless lawn mower comes with two lithium-ion batteries for extended use.
Working time for batteries depends on the cutting condition’s difficulty level. The batteries take about an hour to recharge on the included charging station.
The 16-inch cutting width is ideal for smaller yards and narrow areas along pathways, and the heavy-duty plastic deck frame ensures you won’t have problems with rusting of the undercarriage as the seasons roll by.
The handles on this machine fold down neatly, making the entire unit more compact and easy to store in limited space. You can also use the folded handles for lifting and moving the machine. Along with those conveniences, at only 38 lbs., this unit ranks high for portability, storage, and convenience.

LawnMaster mowers come in three cutting deck widths. This one is the smallest at 15-inches, but they also sell 16-inch and 19-inch deck models powered with 12AMP motors.
The cutting height adjustment leaver moves from 1-inch to 3-inches and is easily worked with one hand and a single motion. Adjusting to a higher cutting blade height makes it easier to tackle taller, tougher grass and move around on uneven terrain.
The handle also adjusts to fit different size operators and users with bigger or smaller paces. This adjustable feature is a great bonus if you have more than one person in the household, taking on mowing the lawn.
A 7-gallon cutting collection bag handles plenty of trimmings when cutting a small to medium-sized lawn. You can also operate the lawnmower without the bag and discharge the cuttings to the side for mulch.

The light, compact, foldable design makes it optimum for homes with limited storage space. The low-maintenance, oil-free operation keeps the cost down for on-going use and makes clean up and storage easy.
- Long run-time
- Torque-Sense technology
- 5-Year Warranty
- Reports of minor problems with “Go” switch at delivery
- Heavy machine weight
- Powerful cutting torque
- 100 plus minutes of run-time with both batteries
- Fast battery recharging time
The Yard Force, 22-inch deck, self-propelled mower is built for maintaining sizable lawns, It has a superb maximum run-time for a battery-driven lawn mower, lasting up to 100 minutes or more with both batteries fully charged and installed.
The dual battery ports use power from one battery then automatically switch to the fresh battery when the first one runs low. You can also run the machine with a single battery in the port while the other battery is on the charger.
The super-powerful, 120-volt brushless motor has force comparable to a gasoline-powered mower engine, giving you the torque needed for tough cutting jobs.
The self-propelled setting on the drive shaft lets you go up and down slopes and hills with minimal effort, and this can be crucial if your landscape includes hilly or rough terrain. The mower also operates in manual drive mode to save battery charge when mowing on flat and level areas.
Using the self-propelled feature has a safety advantage when mowing on an uneven landscape because less operator strength is needed, reducing the risk of damage to the machine in case of an accident. The self-propelled drive is also a plus for quickly cutting tall and tough grass without undue physical effort.
The deck is adaptable to three modes for disposing of the cuttings:
- Side discharge
A unique feature in the bagging design assures a 95 percent capacity of the bag when full due to a special bag/box feature. This feature reduces how often you have to empty clippings, and the bag/box design is also easier to take off of the machine and handle while dumping.
Depending on the grass’s thickness and height, the Torque-Sense technology sensors relay data to the motor, adjusting how much power it puts out and matching it to the job at hand. This feature gives you extra torque and power when cutting damp and wet lawns, and it saves battery power when cutting conditions are easy.
The unit comes with two lithium-ion batteries and one, 4-amp fast charger, and the batteries maintain full-power all the way through the charge without dropping off at the end. The charger recharges the batteries in approximately 30 minutes, which is about half the time of most lawn mower battery chargers.
Compact, vertical storage and folding handles let you stow the unit in 30 percent of other mower’s floor space, which is an important consideration if your storage space is limited.
A significant advantage of battery-powered lawnmowers is the fume-free operation and zero need for buying, storing, and pouring gas and oil to maintain the machine compared to a gas-powered model.
Overview of Yard Force Mower for Uneven Terrain
The Yard Force 3-in-1 Torque-Sense Mower is an excellent choice in battery-powered lawnmowers for homeowners with large yards, uneven landscape, and tough weeds to cut.
This mower has the power and run-time comparable to a gas-powered mower without the fumes and the mess and hazard of gas and oil. The heavy-duty frame construction on this unit is built to withstand many seasons of tough service.
- High-clearance for uneven terrain
- 3-way clipping discharge system
- Rake bumper for finer, closer cut
- Manual propelled
- Gas fumes and storage considerations
- Long run-time
- Exceptional cutting power
- High clearance for uneven ground
The Troy Bilt 21-Inch, 159cc gas walk behind mower is a classic, gas-powered lawn mowing machine with a long tradition of cutting lawns and chopping down tall weeds.
The wide, 21-inch cutting deck lets you mow faster and more efficiently, a feature you will appreciate if you’re mowing a large yard.
Rugged, 11-inch rear wheels give you incredible traction and the high-clearance needed when the terrain is rough, uneven, or the weeds are thick and tall.
The side discharge and 1.9-bushel collection bag give you plenty of room for gathering clippings between stops to empty the bag. You can also take the bag off entirely and use the mulching feature to leave cuttings on the lawn as mulch and return nutrients to the soil.
The rake bumper is a unique feature of this lawnmower that lifts the grass just before it goes under the cutting blade, ensuring a finer cut. This cutting feature also reduces the clumping of cut grass, making the chopped grass and weeds better for mulch or easier to dump from the collection bag.
The machine runs on regular, unleaded gasoline, and it has an easy-start engine with an automatic choke you don’t need to adjust manually. To start up the engine, depress the starter bar on the handle with one hand and pull the starter cord with the other hand.
Releasing the starter bar on the handle automatically shuts off the engine when you’re ready to stop or if you lose control of the machine during operation.
Total weight of just under 66 lbs. makes pushing the mower easy for many operators, but the manual propulsion can be a drawback for some people.
Gas-powered mowers deliver when it comes to run-time, working for over 100 minutes on a single tank of gas, depending on work conditions. Cutting wet or damp grass and tall, thick weeds takes more power than cutting short, dry grass, and these factors affect how often you need to refuel a gas-powered mower like this one.
Another important factor in deciding on which lawnmower to buy is the exposure of people and the environment to fumes during operation and storage of gas and oil when you own a gas-powered machine. Elimination of fumes and simplified storage is a significant advantage of a battery or corded lawnmower.
Spare gas must be stored in an outdoor location, a garage, or a shed in an approved gas storage container. The oil in the machine must be checked before each use and topped off as needed. Occasionally changing the oil, spark plug, and air filter are standard maintenance tasks with a gas-powered lawnmower.
Battery and corded mowers are also quieter than their gas-driven counterparts and this can be an important factor for many homeowners when choosing between a gas mower like this Troy Bilt and a corded or battery-powered unit.
Overview of Troy Bilt Mower for Hilly Terrain
This Troy Bilt gas-powered mower is a great choice for homeowners who have big yards, tough weeds, and uneven ground to mow and storage facilities for spare gas cans and oil.
The gas engine has exceptional power for tough jobs, but it does take some muscle-power to move the machine around.
When you invest in a new lawnmower for rough terrain, you want a machine that can handle your landscape and your needs as an operator. Smaller yards with gentler slopes require a different machine than a ½ acre field with a steep slope.
Some homeowners are comfortable using muscle-power to maneuver a lawnmower around their yard. Others need or want the efficiency and reduced effort provided by a self-propelled mower.
The most crucial point is to match your landscape, your personal needs, and your storage space to the right machine for you.
