LawnMaster CLMF4819X 19-inch Brushless C vs Greenworks 24V 13" Brushless Cordless La
Quick Verdict
The LawnMaster CLMF4819X is the stronger overall choice for most homeowners with small to medium lawns. It offers a wider 19-inch cutting deck, dual battery power (2x24V), and significantly higher user ratings. The Greenworks 24V 13-inch model costs less and suits very small yards or tight spaces, but its narrower cut and lower customer satisfaction make it a more limited tool.

Where LawnMaster Wins
Wider cutting deck – At 19 inches, the LawnMaster covers nearly 50% more ground per pass than the Greenworks 13-inch deck. This makes a real difference in mowing time for any yard larger than a postage stamp.
Higher effective voltage – The dual 24V batteries run in series to deliver 48V-equivalent power. This provides more torque for taller grass and better battery life under load compared to a single 24V system.
Better user satisfaction – With a 4.0 average from over 4,200 reviews, owners consistently report reliable performance and good build quality. The Greenworks trails at 3.6 from 1,200 reviews, where common complaints include weak power in thick grass and short runtime.
Better value for larger lawns – The $66 price difference buys you a mower that can handle nearly three times the yard area, making the LawnMaster the more cost-effective choice for anyone with a lawn over 1,000 square feet.
Where Greenworks Wins
Lower upfront cost – At $131.87, this mower costs about one-third less than the LawnMaster. For someone on a very tight budget or mowing a tiny patch of grass, that savings matters.
Compact and lightweight – The 13-inch deck and single battery make it easier to maneuver in tight flower beds, narrow side yards, or around garden obstacles. It’s also simpler to store in a small shed or garage corner.
Adequate for tiny lawns – If your grass area is less than 1,000 square feet (think small city lot or strip of lawn), the Greenworks can get the job done without the extra cost or weight of a larger mower.
Which Should You Buy
Buy the LawnMaster CLMF4819X if you have a lawn of 1,000 to 5,000 square feet, want to finish mowing in fewer passes, and prefer a mower with proven reliability. The wider deck, dual-battery power, and strong reviews make it the better long-term investment for typical suburban yards.
Buy the Greenworks 24V 13-inch if your lawn is very small (under 1,000 square feet), you need to mow tight spaces regularly, or your budget is strict. It’s a functional tool for minimal grass areas, but be prepared for longer mowing times and possible struggles with thick growth.
For the vast majority of users, the LawnMaster delivers a better balance of performance, coverage, and value.
