Our take on the Ryobi 40V HP Self-Propelled Lawn Mower

A 20-inch cordless walk-behind mower with a brushless motor, rear-wheel drive and variable speed with cruise control. It bags, mulches and side-discharges, and the single-point lever sets any of seven cutting heights from 1.5 to 4 inches. The 6 Ah 40V battery is included and Ryobi rates it for up to 40 minutes, roughly a half acre. It suits homeowners with small to mid-size lawns who want gas-like drive without gas, though runtime and the polymer deck are the trade-offs against beefier gas and premium battery mowers.

What reviewers say

Owners of Ryobi's 40V self-propelled mowers generally praise the easy start, the drive system and the clean cut, and like staying on one battery platform. Common complaints center on runtime on thicker grass, the weight, and the plastic deck and wheels feeling less sturdy than gas mowers.

What people mention
  • RuntimeMixedOwners say the rated 40 minutes holds on light grass but drops in tall or wet conditions.
  • DrivePraisedRear-wheel drive with variable speed and cruise control is called easy to control on slopes.
  • WeightCriticisedAt about 43 lbs it is heavy to maneuver, especially with the drive disengaged.
  • BuildMixedThe polymer deck resists rust but some owners find it and the wheels less solid than steel.
  • Cut qualityPraisedBagging and mulching are reported to leave a clean, even cut.
  • Battery platformPraisedBuyers value sharing the 40V battery with other Ryobi tools.

Questions and answers

How long does the battery last?
Ryobi rates the included 6 Ah battery at up to 40 minutes, about half an acre. Expect less in tall, thick or wet grass, so a second battery helps on larger lawns.
Does it come with a battery and charger?
Yes. One 40V 6 Ah battery and a charger are included, so it is ready to mow out of the box.
Can it mulch, bag and side discharge?
Yes, all three. A plug and chute let you switch between mulching, bagging and side discharge.
How does it compare with a 21-inch gas mower?
It starts with a button, needs no gas or oil and is quieter, but its 20-inch deck is narrower and runtime is limited. A gas mower cuts wider and runs as long as you fill it.
Is it good on slopes?
Rear-wheel drive with variable speed and cruise control gives good traction on moderate slopes. Very steep hills are still a stretch for any walk-behind.
What cutting heights does it offer?
Seven positions from 1.5 to 4 inches, set with a single lever.
Where is the Ryobi 40V HP Self-Propelled Lawn Mower cheapest?
At Arbor, for $326.40, 17% under what the other stores charge, as of our latest check.
Where can I buy the Ryobi 40V HP Self-Propelled Lawn Mower?
3 stores we checked sell it, including Arbor, directtoolsoutlet.com, eBay.
