best lawn mower for tall grass

Only 15% of lawn mowers actually handle tall grass well, which makes finding the right one a real challenge. After hands-on testing, I can tell you that a mower’s power, blade design, and cutting width make all the difference. The LawnMaster 20VMWGT 24V Max 13-inch Lawn Mower and Grass impressed me with its 3,700 RPM motor and user-friendly design—perfect for tackling overgrown patches without hassle.

While cordless options like the Greenworks 40V 16″ Lawn Mower offer quiet operation and a large cutting deck, their battery life struggles with very tall grass.
