RYOBI 40V HP Brushless WHISPER SERIES 21-Inch Self-Propelled AWD Multi-Blade Lawn Mower
$626.99
The RYOBI 40V HP Brushless WHISPER SERIES 21-Inch Lawn Mower is a cordless walk-behind mower designed to provide strong cutting performance with reduced operating noise compared with gas-powered equipment. This version uses RYOBI’s 40V HP brushless technology and a 21-inch multi-blade cutting system for residential lawn maintenance.
The mower is part of RYOBI’s WHISPER SERIES™, which is engineered for quieter operation. RYOBI states that the self-propelled AWD version is up to 85% quieter than gas equipment. It uses a CROSS CUT multi-blade system designed to create finer clippings and improve mulching, bagging, and discharge performance.
The self-propelled all-wheel-drive system sends power to all four wheels to improve traction and control on uneven or sloped terrain. Variable-speed self-propel controls allow the user to match mower speed to walking pace and lawn conditions.
With two 40V battery ports, the mower can provide up to approximately 70 minutes of runtime when equipped with the specified battery configuration. Runtime varies based on grass conditions, cutting height, terrain, battery condition, and operating mode. RYOBI rates this version for lawns up to approximately 3/4 acre.
