Greenworks 40V 21in Self-Propelled Lawn Mower

Best for: Bigger yards needing longer runtime

Pros

• Two 4.0Ah batteries, up to 60 min
• Auto battery switchover
• Smart Pace self-propel
• 7-position height adjust

Cons

• Heaviest single mower at 84 pounds
• 3-in-1, no leaf pickup mode

Best for: Early-morning or evening mowers

Pros

• LED headlight
• 4-in-1 incl. turbo leaf pickup
• Brushless motor, variable speed
• 0Ah battery and charger

Cons

• Runtime not stated
• Heavy at 73.9 pounds listed

The Greenworks 40V 21in Self-Propelled Lawn Mower with a 5.0 Ah battery (model MO40L517) is the most feature-packed 40V mower here. It uses a brushless motor, a design without worn-out carbon brushes that the listing says gives longer runtime, quieter operation and more torque, and it runs 3x quieter than gas. The 21-inch steel deck handles a standard suburban lawn.

Rear-wheel drive with variable speed means you set how fast the mower pulls, which helps on uneven ground. Two features stand out from the other 40V models: an LED headlight for early mornings or evenings, and a 4-in-1 system that can mulch, bag, side discharge or do turbo leaf pickup. The kit includes one 5.0Ah battery and a charger. Ah, or amp-hours, is the battery’s fuel tank size: a higher number generally means longer mowing. The listing does not state runtime, and it lists an item weight of 73.9 pounds.

This model suits someone who mows at odd hours or wants to handle fall leaves with the mower. If you need more runtime on one charge, the two-battery kit below is the better choice.

Greenworks 40V 21″ Self-Propelled Mower,Axial Leaf

Best for: New homeowners building a cordless toolkit

• Mower, blower and trimmer in one
• 500 CFM / 120 MPH blower
• Trimmer converts to edger
• 45 min mower runtime

Cons

• 2-year battery warranty
• Trimmer size listed as 12 and 13 inch

Best for: Small to mid yards on one battery

Pros

• Up to 45 min on 5.0Ah
• 7-position single-lever height
• Brushless motor, steel deck
• 3-year tool and battery warranty

Cons

• No LED headlight listed
• Listed weight looks inconsistent

The Greenworks 40V 21″ Brushless Cordless self-propelled mower is the straightforward option. The listing gives up to 45 minutes of runtime on its included 5.0Ah battery, depending on grass and how you mow. It has a brushless motor, a steel deck, 8-inch front wheels and rear-wheel drive for traction.

A single lever adjusts cutting height across 7 positions, and a 3-in-1 design gives rear bag, side discharge and mulching. It has no LED headlight or leaf pickup mode listed. The spec table shows a 20.28-inch cutting width and a 21.7-pound item weight, which seems light next to the other 40V mowers here, so treat that figure with care. It is described as virtually maintenance-free, with no gas, oil or emissions.

This suits a small to medium yard that can be finished in under 45 minutes. For extra time, choose the two-battery version.

This Greenworks 40V 21in Self-Propelled Lawn Mower kit comes with two 4.0Ah batteries, and the listing gives up to 60 minutes of runtime between them. Dual battery ports with automatic switchover mean that when one battery runs out, the mower switches to the second without stopping.

It uses Smart Pace self-propel, which automatically matches your walking speed, so you do not have to set a dial. Other features include a brushless motor, 21-inch steel deck, 8-inch front wheels, a single-lever 7-position height adjustment and a 3-in-1 design for mulching, side discharge and bagging. It weighs 84 pounds, the heaviest single mower here.

This is the pick for larger lawns or anyone who wants a spare battery for other 40V tools. If you need to cover close to an acre, the 60V mower gives more coverage per charge.

The Greenworks 40V 21″ Self-Propelled Mower,Axial Leaf Blower and String Trimmer bundle is a starter kit for a new homeowner. The mower has 8-inch front wheels, rear-wheel drive, a brushless motor and steel deck, a push-button start and a 3-in-1 deck, with 45 minutes of runtime on a 5.0Ah battery.

The blower delivers 500 CFM and 120 MPH with variable speed and turbo. CFM measures how much air moves and MPH how fast it moves. The trimmer converts to an edger at the push of a button and has a pivoting head. The listing is inconsistent on trimmer size (12 inches in the title, 13 inches in the features) and head positions (90° pivoting in one place, 7-position in another). Batteries and chargers are included, but the listing does not specify how many. Warranty is 3 years on tools and 2 years on batteries.

It makes a generous housewarming gift. Anyone who already owns a trimmer and blower should pick a mower-only kit.

Best for: Larger lots up to 3/4 acre

Pros

• 60V brushless power
• Up to 3/4 acre per charge
• LED headlight and 4-in-1
• 4-year warranty

Cons

• Uses 60V, not 40V, batteries
• Not part of 40V tool line

The Greenworks 60V 21in Self-Propelled Lawn Mower uses a higher-voltage system. Voltage is roughly the strength of the power supply; 60V gives more cutting force for thick grass and slopes. The listing, which calls it the Greenworks Pro 60V in the description, promises gas-like power, 3200 RPM and coverage of up to 3/4 acre per charge.

It includes two 4.0Ah batteries with auto switchover for 60+ minutes, rear-wheel drive with on-the-go speed, an LED headlight and a 4-in-1 system with turbo leaf pickup. It runs 3x quieter than gas and weighs 65 pounds. Warranty is 4 years on tool and battery. Its batteries fit the 60V tool line, not 40V tools.

This suits yards of half an acre or more. For very large properties, our Greenworks zero turn mower guide covers riding options.

Best for: Heavy-use and landscaping crews

Pros

• Four batteries included
• Commercial 48V/24V design
• 7 cutting heights, steel deck

Cons

• Very short feature list
• No bagging mentioned

The 21″ Dual-Volt Self Propelled Lawn Mower from Greenworks Commercial is built for professional use. It runs on a 48V/24V system with four batteries and a charger included, which the description says ensures extended operation.

Features are brief: 2-in-1 mulching and rear discharge, 7 cutting heights and a durable steel deck. It weighs 28 kg (about 62 pounds). The listing does not state runtime, warranty or whether it bags clippings.

It suits landscaping crews or homeowners with heavy mowing needs. Most households will be better served by a 40V or 60V model with clearer specs.
