Walk-Behind Concrete Saw Horsepower Ratings: Matching Saws to 14" to 36" Blades
Direct Answer: Matching walk-behind floor saw engine horsepower to blade diameter ensures maximum cut speed without stalling saw motors: 13HP to 18HP saws run 14" to 18" blades (4"–6.5" depth); 24HP to 35HP gas/diesel saws run 20" to 24" blades (7.5"–9.5" depth); and heavy-duty 45HP to 72HP diesel saws drive 30" to 36" blades (12"–15" depth). Under-powering large blades causes motor stalling, while over-powering small blades warps cores.
