6 Best Lawn Mowers for 15 Inch Grass of 2025

The BLACK+DECKER BEMW472BH comes out swinging with a 10-amp motor and a 15-inch deck that chews through overgrown patches better than most compact electrics. Its bike-style handle isn’t just a gimmick—it reduces wrist strain and gives tighter control when you’re wrangling tall or damp grass. With six height settings (1–3 inches) and a winged blade for 30% better collection, it’s tailored for anyone frustrated by clumping and constant raking.

In testing, the 120V corded setup delivers steady power, crucial when tackling 15-inch grass—take it in progressive passes and it won’t bog like smaller cordless units. The mower’s lightweight chassis helps when muscling through thicker areas, and the push-button start makes stop-and-go trimming painless. Bagging is effective thanks to the enhanced airflow, though you’ll still want to take narrower swaths in very dense growth.

Against the LawnMaster MEB1114K, the BLACK+DECKER offers stronger suction and better collection control, while the American Lawn Mower Company 13-amp model beats it on raw width for big backyards. If you want consistent power and superior clippings management for small lawns, this is the no-fuss pick. Compared to the LawnMaster cordless CLMF4815E, BLACK+DECKER trades portability for more stable performance in tall grass.

LawnMaster’s MEB1114K brings a punchy 11-amp motor at 3,300 RPM to a compact 14–15 inch class deck, a smart formula when you’re battling tall, neglected grass. The 7.75-inch rear wheels improve tracking over uneven ground, and the 5-position height adjustment (1.4–3 inches) lets you stage cuts to avoid stalls. At just 28 lbs with folding handles, it’s built for small yards where storage space is tight.

In real-world mowing, it handles 15-inch grass best with a two-pass approach: start high, then step down to refine the cut and keep the 7-gallon bag from clogging. The motor’s consistent RPM helps maintain blade speed through thicker sections, though the narrower deck means more laps on mid-size areas. Navigation around trees and beds is a highlight, and the corded design ensures no runtime anxiety during long sessions.

Compared with the BLACK+DECKER BEMW472BH, the LawnMaster is lighter and more nimble, but the BLACK+DECKER’s clipping collection is stronger in heavy growth. It also can’t match the 19-inch cutting efficiency of the American Lawn Mower Company 13-amp model on larger lawns. For users prioritizing maneuverability and compact storage over width, it’s the nimble corded choice that undercuts the cordless CLMF4815E on sustained power.

The American Lawn Mower Company 51319 is a workhorse 13-amp corded mower with a wide 19-inch deck, designed for tackling taller grass in fewer passes. It offers mulch and rear-bag modes with included accessories, letting you switch from dense overgrowth cleanup to nutrient-return mulching. With 1–3 inch height adjustment and straightforward push operation, it’s a pragmatic upgrade for users who’ve outgrown compact 14–15 inch mowers.

In testing on grass approaching 15 inches, the 13-amp motor maintains blade speed better than typical 10–11 amp peers, especially when you stage cuts from high to medium. The broader deck clears more per pass, reducing time—and with mulching turned off, bagging airflow stays solid into thicker clippings. Weight and size mean it’s less agile around tight beds, and cord routing needs forethought on larger plots.

Versus the BLACK+DECKER BEMW472BH, this model wins on coverage and motor headroom, but loses some fine maneuverability in tight areas. Compared to the LawnMaster MEB1114K, it’s the better option for larger yards or very tall grass thanks to the 19-inch deck. If you need a corded mower that handles taller grass capacity with fewer passes, this is the productivity pick over the smaller cordless CLMF4815E.

The LawnMaster CLMF4815E brings cordless freedom with a dual 24V (48V max) brushless system spinning at 3,100 RPM, ideal when high grass forces frequent repositioning. Its 15.5-inch deck and 6.7-inch rear wheels help it weave around obstacles where cords snag. With 4 height settings (1.4–2.5 inches) and up to 35 minutes of runtime, it’s purpose-built for small lawns that need nimble, no-fuss mowing.

On 15-inch grass, the brushless motor provides smooth torque delivery, but you’ll get best results taking incremental cuts and avoiding full-width bites in dense patches to preserve runtime. The bagging works fine for spot overgrowth, though the lower max height (2.5 inches) may require an initial high cut followed by a finishing pass. It’s easy to store thanks to the folding handle and carrying handle for transport.

Compared with BLACK+DECKER’s corded 10-amp unit, this LawnMaster sacrifices sustained power for mobility and convenience. It can’t match the 19-inch throughput of the American Lawn Mower Company 13-amp model but beats it on maneuverability and setup time. For homeowners prioritizing cordless agility over raw power in tall grass, it’s a clean, quiet upgrade; versus the DEKOPRO 40V, it trades slightly lower cut height for a more refined brushless drive.

DEKOPRO’s 40V cordless mower hits a sweet spot with a 15-inch blade, 6-position height (0.98–2.95 inches), and a 40L bag, tuned for small yards that occasionally get overgrown. The brushless motor runs quiet and low-vibration, an advantage when you’re making multiple staged passes through tall grass. The folding, adjustable handle supports comfortable posture and compact storage.

In tall growth around 15 inches, start high on the first pass—DEKOPRO even recommends this—to reduce clogging and keep the blade speed up. The twin 4.0Ah batteries deliver practical runtime for small properties; expect to preserve juice by narrowing the swath in thick patches and using the bag for cleanup. Collection is competent, and the near-3-inch top height provides more flexibility than some compact cordless rivals.

Against the LawnMaster CLMF4815E, DEKOPRO offers a slightly higher maximum cut height and a larger bag, though the LawnMaster’s brushless drive feels a bit punchier at the blade. Compared to corded options like BLACK+DECKER, it gives up continuous power but wins on mobility and noise. For owners seeking a lightweight cordless that handles tall grass with careful staging, it’s the more forgiving cut height choice.

WEN’s 20VK2MLB combo delivers two essentials: a 15-inch brushless mower for the main pass and a string trimmer/edger with adjustable width for cleanup—perfect when tall grass creeps along fences and borders. The collapsible handle lets the mower store upright, while the trimmer’s telescoping body (41.5–49.5 inches) adapts to different users. For small lawns that surge past mowing day, the dual-tool setup streamlines reclaiming control.

In taller growth, the brushless mower handles thick sections best with staged heights and measured pace, while the trimmer edges down stubborn tufts around posts and beds. The single 5Ah battery simplifies charging, though swapping between tools is part of the rhythm on bigger jobs. Upright storage and light chassis make the kit friendly for garages or sheds with limited space.

Compared to the DEKOPRO 40V mower, WEN’s combo trades pure mowing runtime for an all-in-one mow-and-trim workflow that’s invaluable for overgrown edges. It won’t match the 19-inch throughput of the American Lawn Mower Company corded unit, but you gain cordless convenience and integrated edging. For users who want a tidy finish on taller grass without separate purchases, this kit offers strong feature value versus single-tool cordless options.
