Ryobi 40V HP 21-inch Self-Propelled Mower RY401150

Cross Cut Multi-Blade System and Adaptive Variable Speed Set This Ryobi Mower Apart

The Ryobi High-Performance tech has made its way to the 40V platform, and what better way to show it off than to throw it into a mower? The Ryobi 40V HP self-propelled mower uses a Cross Cut twin-blade system and Smart Trek adaptive speed controls. It looks to offer the power and performance of gas with the convenience of electric power.

Ryobi 40V HP Self-propelled Mower Overview

There are probably a few things worth mentioning with the Ryobi 40V HP self-propelled mower. We’ll start with the 40V HP battery platform Ryobi put in this system.

As a general rule, the 40V HP tool line uses tools with brushless motors. These deliver more power, performance, and run time. In the case of the Ryobi 40V HP self-propelled mower, that means you get up to 70 minutes of run time using the kitted pair of 6.0Ah batteries. Ryobi estimates that this should be ideal for lots of 3/4 of an acre or less.

Cross Cut twin blade system

The Ryobi RY401150’s Cross Cut multiple blade system employs technology similar to what we first saw with Yamaha MicroCut twin blades. It employs a pair of offset blades. These provide superior cutting and mulching while maintaining excellent airlift for bagging applications.

Finally, the Ryobi 40V HP Self-Propelled Mower features a Smart Trek self-propelled paddle drive. This system differs a bit from the former Smart Trek system. Now, you get a unique thumb paddle design.

You simply push on the paddle to activate the self-propelled drive mechanism. You still get to set the maximum speed using the horizontal slider just above the paddle, but the sensitive system gives you much more fine control over speed. This comes in handy for turns. In particular, it lets you easily back off the drive speed when making tight corners so you don’t tear up your lawn.

Our Thoughts

We’ve had mixed experiences with the former Smart Trek system, but this new system looks to address all our concerns. We love the fine adjustment possible with the thumb paddles, and the dual-blades should provide superior cut quality and mulching. Lastly, this mower is made right here in Anderson, SC. Who doesn’t love the idea of an American-made mower?!

At $599, Ryobi is stepping into premium battery-powered mower territory. It does so, however, with an excellent value by including a pair of 6Ah 40V battery packs. That makes this mower capable of covering a lot of ground.

We look forward to completing our review of this mower shortly—at which point we’ll update this review with our findings. In the meantime, we wanted to get as much information out to our readers as possible.
