GreenWorks Pro 80v Review: Deep Dive

Cutting Power

The GreenWorks 21-inch 80V cordless lawn mower’s cutting power is one of its biggest selling points. It’s powered by a 80V battery that offers up to 60 minutes run time when charged to full capacity. Within 60 minutes, the 4.0 AH battery will be fully charged while it takes 30 minutes to charge the 2 AH version fully.

The long run time and short charge time give users enough cutting power to get much done in a short time. To avoid being stuck midway through a mowing session when your battery unexpectedly goes dead, always have an extra battery as backup.

The mower boasts of a Smart Cut Technology that enables it to adjust its cutting power according to the projected load. Thus, while mowing towards thicker or taller grass, the mowing machine will automatically increase its power to enable it to handle the task easily.

Cutting Area

If you use the 2.0AH battery model, you may get a run time of 45 minutes, enough time to mow about a quarter of an acre while you can mow more with the 4.0AH type. The machine’s 21-inch cutting width increases the mower’s cutting performance and extends its cutting area.

Noise Level

You won’t get noise complaints from your neighbors when mowing with the GreenWorks 80V cordless lawn mower. The machine runs so quietly that your neighbor will hardly notice you are mowing unless they see you at work. 

If you are used to wearing ear protection while mowing with noisy mowers, you definitely won’t be needing them when using the GreenWorks PRO 80V cordless mower.


Smooth operation is the hallmark of GreenWorks lawn mowers. This model and several others in the same category come with a start button that users can switch the machine on with, unlike other models that require exerting your physical energy by pulling a rope.

That aside, the lawn mower is lightweight which means you can easily push it around your lawn and around potential obstacles.

The GreenWorks PRO 80V cordless mower comes with a 4-year warranty from GreenWorks. While the warranty lasts, the manufacturer will replace, repair, or issue a refund if the product is defective or damaged during shipping.

It’s important to note that the 4-year warranty is valid on the condition that you use the mower for domestic purposes only. If you use it for business, the company is responsible for defects in just 90 days.

Mower Quality

The GreenWorks 21-inch 80V cordless lawn mower is made of the best quality material. Its steel deck makes it a very durable machine at par with many gas-powered mowers.

Replacement Parts

Replacement parts are readily available for the GreenWorks 21-inch 80V cordless mower. Greenworks and some accredited retailers have these parts in stock so you can order from them. 

When placing your order, ensure that you get the right blade since that is compatible with the mowing machine. Aside from the blades, chargers, batteries, and some other accessories are available.

Bottom Line

The GreenWorks 80V 21-inch combines a great battery run time with the ability to automatically adjust itself for the best mowing experience, even when working through thick grass.

Although the mower isn’t as light as others in the same category, that doesn’t take anything away from its overall performance.
