Ryobi 40V HP Brushless 21 in. Cross Cut AWD Self-Propelled Lawn Mower Kit (2 × 6.0 Ah)

Model number
RY40HPLM03K2

The Ryobi RY40HPLM03K2 is Ryobi's flagship 40V HP push-walk mower, combining all-wheel drive self-propulsion with the CROSS CUT dual-blade system. It is the only cordless AWD mower available in the 40V HP lineup, making it the recommended choice for hilly or uneven terrain where rear-wheel drive models can lose traction. The brushless motor is rated at 196cc gas equivalent, the highest in the 21 in. 40V HP mower range. Two 6.0 Ah batteries provide up to 75 minutes of runtime. SMART TREK adaptive speed control and the Cut Command Center display are both included. Ten cutting height positions span 1.5–4 in., and the deck handles bag, mulch, and side-discharge functions.

§ FAQ

Is the RY40HPLM03K2 really all-wheel drive?

Yes. The RY40HPLM03K2 is Ryobi's only cordless all-wheel drive lawn mower. AWD distributes drive power to all four wheels simultaneously, maintaining traction on hills and uneven ground where rear-wheel drive models can slip.

What is the CROSS CUT system on this mower?

CROSS CUT uses two stacked blades rotating in the same deck to shred clippings more finely than a single blade. This reduces visible clumping on the lawn surface and improves bagging efficiency by approximately 75% according to Ryobi's claims.

How much runtime does the RY40HPLM03K2 provide?

With two 6.0 Ah 40V HP batteries, the mower delivers up to 75 minutes of runtime. Both batteries are used concurrently for full power output throughout the session.

What gas engine does this mower replace?

Ryobi rates the RY40HPLM03K2 at a 196cc gas equivalent, the highest rating among the 21 in. 40V HP mower models. This reflects the combined power demands of AWD and the CROSS CUT dual-blade system.

Is this the right mower for a hilly yard?

Yes. AWD self-propulsion makes the RY40HPLM03K2 the best choice in the 40V HP lineup for slopes and uneven terrain. Rear-wheel drive models like the RY40HPLM01K2 and RY40HPLM02K2 can lose traction on inclines, whereas all-wheel drive maintains grip with all four wheels engaged.
