Greenworks 80V 21in Push Lawn Mower or Greenworks 60V 17in Push Lawn Mower? Which Greenworks Model to Buy

Key differences

Which one should you choose?

80V vs 60V Mower Specs

Voltage and power

Edge: Greenworks 80V 21-Inch Cordless Push Mower

The Greenworks 80V 21-Inch model operates at 80V, while the Greenworks 60V 17-Inch model runs on 60V. Higher voltage generally supports greater torque and sustained power output under load. Both units use a brushless motor for efficiency, but the 80V system provides a higher potential energy baseline. This difference may matter if you face thick or wet grass that demands more cutting force. The 60V platform is designed for lighter to moderate tasks. You should consider your typical grass density when weighing this spec. The 80V mower has the edge here for raw power potential.

Cutting width

Edge: Greenworks 80V 21-Inch Cordless Push Mower

Deck width determines how much grass you cut per pass. The Greenworks 80V 21-Inch model features a 21-inch cutting deck. The Greenworks 60V 17-Inch model has a narrower 17-inch deck. A wider deck covers more ground in less time, which is useful for larger lawns. The 17-inch width allows for tighter maneuvering around obstacles like flower beds or trees. If you have a wide-open yard, the 21-inch option reduces the number of passes needed. For small, cluttered spaces, the 17-inch deck is easier to handle. The 80V mower wins for speed on open terrain.

Runtime and charge time

Edge: Greenworks 80V 21-Inch Cordless Push Mower

Battery runtime dictates how long you can mow before recharging. The 80V model offers up to 60 minutes of run-time with its 4.0 Ah battery. The 60V model provides up to 40 minutes on the same capacity battery. The 60V unit also notes a quick recharge time of just 90 minutes. Longer runtime is beneficial for larger areas where you cannot stop mid-job. The 80V mower allows for more extensive mowing sessions without interruption. However, the faster charge of the 60V model helps if you need to pause and resume quickly. The 80V mower has the edge for longer continuous operation.

Weight and maneuverability

Edge: Greenworks 60V 17-Inch Push Lawn Mower

Weight affects how easy the mower is to push and store. The Greenworks 80V 21-Inch model weighs 74.1 pounds. The Greenworks 60V 17-Inch model weighs only 37.5 pounds. The 60V mower is significantly lighter, making it much easier to lift, carry, or maneuver in tight spaces. This lightweight design is ideal for navigating uneven terrain or small yards where frequent direction changes are needed. The heavier 80V model may feel more stable but requires more effort to push. For ease of handling, the lighter option is clearly superior. The 60V mower takes the edge here.

Cutting height settings

Edge: Greenworks 80V 21-Inch Cordless Push Mower

Cutting height adjustment allows you to tailor the grass length. The 80V mower offers 7 positions for height adjustment. The 60V mower provides 6 positions, ranging from 1.5 inches to 3.15 inches. The 80V model gives you one additional setting, offering finer control over your cut height. This extra position can help you achieve a precise look for different grass types. The 60V model’s range is sufficient for most standard lawn care needs. Both systems allow you to adapt to varying grass conditions. The 80V mower has a slight edge with the extra adjustment option.

Mowing functions

Edge: Greenworks 80V 21-Inch Cordless Push Mower

Mowing functions define how you handle clippings. The 80V model supports a 3-in-1 system: mulching, rear bagging, and side discharge. The 60V model offers a 2-in-1 system with mulching and rear bagging only. Side discharge allows you to clear clippings to the side, which is useful for wet grass or heavy growth that might clog a bag. The 60V model lacks this specific function, limiting your options in challenging conditions. If you frequently deal with thick grass, the side discharge feature is valuable. The 80V mower provides more versatility in disposal methods.

Which Greenworks mower fits your yard

Users with large, open lawns needing wide coverage

Our pick: Greenworks 80V 21-Inch Cordless Push Mower

The 21-inch cutting deck covers more ground per pass than the 17-inch model. This wider swath reduces the number of passes required to finish a larger area. With up to 60 minutes of runtime on the 4.0 Ah battery, you can tackle bigger yards without stopping to recharge. The 7-position height adjustment also offers greater flexibility for varying grass conditions.

Those with small yards or tight spaces

Our pick: Greenworks 60V 17-Inch Push Lawn Mower

Weighing just 37.5 pounds, this model is significantly lighter than the 80V version. The 17-inch deck is narrower, making it easier to maneuver around obstacles and in confined areas. Its compact size and rust-resistant deck ensure durable handling in tight spaces. The 6-position height adjustment provides sufficient control for smaller, more intricate lawn layouts.

Buyers prioritizing lightweight handling and warranty coverage

Our pick: Greenworks 60V 17-Inch Push Lawn Mower

At 37.5 pounds, this mower is much easier to push and lift than the 74.1-pound 80V model. It comes with a 4-year limited warranty for the tool and battery, offering peace of mind. The 90-minute recharge time is fast, and the 2-in-1 mulch and bag system keeps maintenance simple for owners who value ease of use and long-term support.
