Good walk-behind brush cutters include the Poulan Pro PR22WT Wheeled Trimmer, DR Field and Brush Mower and Swisher WB11524BS Predator, according to Bestweedeaters.com. Brush cutters are ideal for clearing weeds, overgrown grass and shrubbery.
The Poulan Pro has slightly smaller wheels than most brush cutters, making it great for use on flatter areas and for cutting tall weeds and grasses. The DR Field and Brush Mower cuts through grasses up to 8 feet tall, and clears weeds and undergrowth for hours, making it a good choice when clearing large areas. The Swisher Predator has an enclosed blade that powers through dense brush and cuts saplings up to 1 1/2 inches in diameter.
