Best Ryobi Lawn Mowers for 2026: 18V, 40V HP, and 80V Models Compared

Ryobi sorts its outdoor tools into battery systems: 18V ONE+, 40V, and 80V. Pick the system first, because that decides which batteries you'll share with your trimmer and blower. Per Ryobi, the 18V ONE+ system has over 300 products and the 40V system over 85. Ryobi's mower pages list each mower under one system, so check the battery system before you buy a bare tool.

Ryobi Mowers at a Glance

All figures per ryobitools.com as of September 30, 2026. Runtime ratings are Ryobi's; longer, thicker, or wet grass shortens them.

40V HP Mowers (Where Most Buyers Should Start)

40V HP Brushless 21" Self-Propelled (RY40HPLM01K2) - Our Pick

Per Ryobi, this mower pairs a brushless motor with self-propelled, variable-speed rear-wheel drive. Ryobi says it delivers more power than a 163cc gas mower, is ideal for 3/4 acre or less, and runs up to 80 minutes on two 40V 6Ah batteries (included in the RY40HPLM01K2 kit). A Cut Command Center lets you monitor runtime and blade life, switch on Turbo Mode and the lights, and adjust drive speed. It has an integrated mulch plug you switch with a lever, pass-through bag removal, and handles that fold for vertical storage. If you already own 40V batteries, Ryobi also sells it as a bare tool (RY40HPLM01B).

40V HP Brushless 21" Push (RY40HPLM05K) - Smaller Yards

Per Ryobi, the push version has the same 163cc-gas power claim, Cut Command Center, Turbo Mode, and mulch plug, and is rated for 1/2 acre or less with up to 55 minutes on a 40V 8Ah battery. There is no self-propel, so you push it.

40V HP Brushless 21" Self-Propelled AWD Multi-Blade (RY401210) - All-Wheel Drive

Per Ryobi, this model drives all four wheels for control on uneven ground and uses the CROSS CUT multi-blade system for finer clippings when mulching. It uses Ryobi's SMART TREK self-propel, which adjusts to your pace, and has an on-board fuel gauge. Ryobi rates it for 3/4 acre or less with up to 70 minutes on two 40V 6Ah batteries and says it's 85% quieter than gas (part of its WHISPER SERIES). Ryobi's site lists the earlier non-AWD multi-blade kit (RY401150) as discontinued.

18V ONE+ HP 16" Push (P1109BTL) - Tiny Yards

Per Ryobi, the 18V ONE+ HP 16-inch push mower is ideal for 1/3 acre or less and runs up to 40 minutes on two 18V ONE+ 4Ah batteries. It has 7 cutting heights from 1.5 to 4 inches, pass-through bag removal, and folding handles. It makes the most sense if you already own ONE+ tools and batteries and your lawn is small. Note the rating assumes two 4Ah batteries, so smaller drill batteries will give you less.

80V Riding Mowers - Large Properties

R1 80V HP 30" Riding Mower (RY80HPRM05K-R1)

Per Ryobi, the R1 uses 3 brushless motors, which Ryobi says deliver more power than a 16 hp gas engine, and is rated for up to 1 acre per charge in ECO mode on the included 80V 14Ah battery. Ryobi says it fits through most standard gates, has an integrated storage bed and a digital display that connects to the Ryobi app, and charges on board. There's no gas, oil, or belts to maintain.

ZR3 80V HP 42" Zero Turn (RY80HPRM04K-ZR3)

Per Ryobi, the ZR3 uses 4 brushless motors, which Ryobi rates at the power of a 25 hp gas engine, and is rated for up to 2 acres per charge in ECO mode on two included 80V 14Ah batteries. It has a 12-gauge fabricated steel deck, front and rear 2-inch hitches for towing up to 250 pounds, steering assist, and on-board charging. Before buying any zero-turn, check your slopes: our zero-turn mower guide covers the OSHA and CPSC slope guidance.

The Amazon Options

EGO LM2114SP - Non-Ryobi Alternative

If you aren't already on Ryobi 40V batteries, this EGO kit is sold by Amazon. Per EGO, it delivers up to 6.0 ft-lb of cutting torque from a brushless motor, runs up to 50 minutes on the included 56V 6.0Ah battery, and has a dual-toggle handle that lets you engage the self-propel with either hand. It has a dial for speed, 7 cutting heights from 1.25 to 4 inches, mulch/bag/side discharge, and LED headlights, and it folds for storage. EGO's warranty is 5 years on the mower and 3 years on the battery. EGO batteries don't fit Ryobi tools. For more EGO options, see our EGO lawn mower guide.

Ryobi 40V 4.0Ah Battery and Charger Kit

Per the listing, this kit pairs a genuine Ryobi 40V 4.0Ah battery (OP40404) with a charger (OP403A). The battery fits the 40V mowers above, not the 18V ONE+ or 80V models, and the same battery runs Ryobi's other 40V tools, its snow blowers included. It was sold by a third-party seller when we checked.

How to Choose a Ryobi Mower

Match the system to your tools: if you already own Ryobi 40V or 18V ONE+ tools, a mower on the same system lets you share batteries, and a bare-tool mower saves you buying another battery. Match the rating to your lawn: Ryobi rates each mower by yard size (1/3, 1/2, or 3/4 acre for walk-behinds, and up to 1 or 2 acres per charge for the 80V riders). Slopes: the 40V HP self-propelled models give you rear-wheel or all-wheel drive. With any walk-behind, mow across slopes, not up and down.

Bottom Line

For most Ryobi buyers, our pick is the 40V HP Brushless 21" Self-Propelled (RY40HPLM01K2). The 40V HP push suits yards of 1/2 acre or less, and the 18V ONE+ HP 16" suits very small lawns. For bigger properties, look at the 80V R1 rider or the ZR3 zero-turn. Buy Ryobi mowers at The Home Depot or ryobitools.com. If you're not on Ryobi batteries, the EGO LM2114SP is sold by Amazon.
