EGO Power+ 21" Self-Propelled Mower vs Ryobi 40V HP Self-Propelled Lawn Mower

The EGO Power+ is the stronger mower for most people: a wider 21-inch cut, a 56V 7.5Ah battery with longer runtime, and the Select Cut multi-blade system that lets you swap blades for mulching or bagging. The Ryobi 40V HP is a solid step-down that runs on Ryobi's 40V battery line and adds cruise control, but it cuts narrower, runs shorter, and its 1.5-inch minimum height leaves taller grass. Owners of both praise the brushless motors and polymer decks; the EGO is the one reviewers treat as a near-gas replacement.

  • Choose the EGO Power+ 21-Inch if you want the widest cut, the longest runtime per charge, and the most flexible mulching and bagging setup.
  • Choose the Ryobi 40V HP if you already own Ryobi 40V batteries and tools, or you want cruise control on a self-propelled mower.

What reviewers say

EGO Power+ 21" Self-Propelled Mower

Owners and reviewers generally rate the EGO Power+ 21-inch mower highly for its quiet, fume-free operation and gas-like power. Many appreciate the self-propelled drive and mulching performance, though some mention that run time can be shorter than expected in heavy grass and that the mower is heavy.

What people mention
  • Run timeMixedSome say the battery lasts up to 50 minutes, while others report shorter run times in tall or wet grass.
  • WeightCriticisedThe mower is heavy with the battery installed, making it harder to maneuver in tight spots.
  • NoisePraisedOwners appreciate how quiet it is compared to gas mowers, allowing early morning mowing without disturbing neighbors.
  • Self-propelled drivePraisedThe variable-speed self-propelled system is often highlighted as making mowing less tiring.

Ryobi 40V HP Self-Propelled Lawn Mower

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.

Questions and answers

Which is better for a large yard?
The EGO. Its 21-inch deck and up-to-50-minute runtime cover more ground per pass and per charge than the Ryobi's 20-inch deck and 40-minute runtime.
Which cuts grass shorter?
The EGO. It goes down to 1 inch (1.25 inches on some listings), while the Ryobi stops at 1.5 inches.
Is the EGO worth stepping up to over the Ryobi?
If you don't already own Ryobi 40V batteries, yes. The EGO gives a wider cut, longer runtime and swappable blades. If you have a shelf of Ryobi 40V tools, the Ryobi's shared batteries are a real advantage.
Which is easier to push?
Both are self-propelled with variable speed. The Ryobi adds cruise control and weighs less, so it feels lighter to handle; the EGO is heavier but has a wider stance.
Do both mulch, bag and side discharge?
Yes. Both are 3-in-1 mowers. The EGO's Select Cut system lets you change blades for each mode, which the Ryobi's single blade does not.
Which lasts longer on one charge?
The EGO, rated up to 50 minutes versus up to 40 for the Ryobi. Real runtime depends on grass height and whether self-propel is engaged.
