The Ryobi RY40HPLM01B is the tool-only version of Ryobi's 40V HP brushless 21 in. self-propelled lawn mower, designed for homeowners who already own 40V HP batteries. The brushless motor is rated equivalent to a 163cc gas engine and powers a variable-speed rear-wheel drive system with SMART TREK adaptive speed control that automatically matches the mower's pace to your walking speed. The Cut Command Center display gives at-a-glance feedback on runtime and motor load. Ten cutting height positions span 1–4 in. to handle a variety of grass conditions, and the mower supports bag, mulch, and side-discharge functions. As a bare tool, no battery or charger is included.

What is SMART TREK on this mower?
SMART TREK is Ryobi's adaptive drive speed system. It automatically adjusts the rear-wheel drive speed to match your natural walking pace, so you do not have to manually set a drive speed lever. This reduces operator fatigue on longer mowing sessions.

The mower offers 10 cutting height positions ranging from 1 in. to 4 in., providing enough range to handle fine turf maintenance through taller rough-cut conditions.

The RY40HPLM01B supports three cutting modes: bagging (using the included grass bag), mulching (using the included mulch plug), and side discharge (using the included chute).
What gas engine does this mower replace?
Ryobi rates the 40V HP brushless motor in the RY40HPLM01B equivalent to a 163cc gas engine, which represents a mid-range walk-behind mower in traditional gas terms.
