Ryobi 40V HP Brushless 21 in. Push Multi-Blade Lawn Mower Kit (2 × 6.0 Ah)

Model number
RY40HPLM04K2

The Ryobi RY40HPLM04K2 brings the CROSS CUT dual-blade system to a push-format 21 in. 40V HP mower, offering the clipping-quality benefits of multi-blade cutting without the added cost of a self-propelled drive system. Two 6.0 Ah batteries deliver up to 80 minutes of runtime. The CROSS CUT system stacks two blades to finely shred clippings and reduce clumping, improving bagging efficiency by approximately 75% over a single-blade design. The brushless motor is rated at a 196cc gas equivalent. The Cut Command Center display is included, and 10 cutting height positions span 1.5–4 in. across bag, mulch, and side-discharge modes. This mower is a strong value for flat-yard owners who want top-tier cut quality without paying for self-propulsion.

§ FAQ

Why choose the RY40HPLM04K2 over the self-propelled multi-blade model?

The RY40HPLM04K2 delivers the same CROSS CUT multi-blade cutting quality as the RY40HPLM02K2 and RY40HPLM03K2 at a lower price point by omitting the self-propelled drive system. It is the right choice for flat yards where push operation is comfortable and the savings outweigh the convenience of self-propulsion.

How long does the battery last on the RY40HPLM04K2?

With two 6.0 Ah 40V HP batteries, the mower runs up to 80 minutes per charge — slightly more than the self-propelled multi-blade models because it does not power a drive motor.

What is the CROSS CUT blade system?

CROSS CUT uses two blades stacked in the same deck to create overlapping cutting action. This shreds clippings more finely than a single blade, reducing clumping on the lawn and improving bagging efficiency by approximately 75% per Ryobi's data.

Does the RY40HPLM04K2 include the Cut Command Center?

Yes. The Cut Command Center display is included, providing real-time battery status and motor load information, as well as access to turbo mode for heavy grass conditions.

What are the cutting height options?

The mower offers 10 cutting height positions spanning 1.5 in. to 4 in., and supports bagging, mulching, and side discharge using the included accessories.
