Ryobi 40V HP Brushless 21" CrossCut Self-Propelled
- CrossCut dual-blade system produces finely chopped mulch clippings (Tool Review Zone)
- Survived thick-grass stress test nearly as long as the $1,199 Milwaukee (The Lawn Review)
- Folds vertically for compact garage storage; lightweight enough to push with two fingers on concrete (Automotive Anonymous)

The Verdict
Our Bottom Line
The Milwaukee M18 Fuel won because it cuts grass better than anything else running on batteries. The Lawn Review put five premium mowers through a multi-stage gauntlet, and the Milwaukee's steel deck and under-deck airflow design produced a visibly cleaner lawn than every competitor. Zero stragglers. Zero mohawks. The difference was obvious in side-by-side photos.
