Greenworks Pro 60V 21-Inch Review

One of the newest innovations in yard work is using battery-powered tools. The benefits include no fumes, no maintenance, no gas, and no power. In our opinion, the 60V line has been the most successful for Greenworks. The original mower was a nice upgrade, and now we have a couple of generations in with the Greenworks Pro 60V 21-inch self-propelled lawn mower. Upgraded features, a durable steel deck, and excellent runtime highlight this all-around excellent performer.

Design and Build


Greenworks has a variety of different models to make your lawn or garden work for you. Our 21-inch steel decks are perfect for Florida. It is hard for us to imagine life without these self-propelled models with hefty 20-inch blades. As many battery-powered mowers do, the Greenworks Pro 60V comes with a single-point height adjustment. This adjustment allows you to adjust the height with 7 positions from 1.38 to 4 inches.


One of the features that make the Greenworks Pro 60V 21-inch self-propelled mower more interesting is its ability to charge two batteries independently. As evidenced by a large number of push mowers, some have implemented dual battery ports; however not all feature automatic battery switching as Greenworks does. The mower signals when one battery is close to death, so the mower will automatically switch to the second battery.

The mower will switch over. The driving pace will increase as the battery charges from nearly depleted mode to a full state.

One of the best features of the new mower is the battery level gauge. It lets you know which battery pack your mower is drawing power from, and what power each battery has at any given time. This feature is a dramatic improvement over having to estimate how much power you have left with a guess based on whether or not your battery was fully charged.

This mower has a battery system so it’s easy to use. It includes two 4.0Ah batteries, so you can operate on both ports without needing a second battery. Greenworks also includes a dual-port charger, so you can charge the mower and forget it until it’s time to mow each time.

Turbo Mode

The new Greenworks Pro mower adjusts the speed of the blade to maintain cutting performance. It’s yet another benefit of having a brushless motor. However, this mower features a Turbo Mode that works at a higher speed if needed.

The auto speed adjustment might kick the blade RPM up, but there is a governor limiting the top end to help you preserve the best runtime. Turbo Mode acts like a manual override that tells the mower to engage its full cutting potential regardless of efficiency.

For people who compost and use a lawn service, this might not be a feature that they often need to use. However, we were able to complete all of our field testings in Bahia and St. Augustine without ever needing this system. However, if you’re camping or going on a long trip, it’s a great feature to have. If you’re going on vacation and can only stay home for a few days, the extra power reduces your runtime so you’ll only need to use it if needed.


The 60V lawnmower makes it easier for people to quickly store their mowers vertically. This new handle mechanism changes the older model from horizontal storage to vertical storage.

Greenworks mowers, rather than requiring users to bend down to reach the handle and release or adjust it, now provide a finger-hold on each side of the handlebars. Customers can pull on the latches with their fingers to move the handle into position before releasing them. The handle folds into place, letting you store the stand in a wide variety of ways.


The new control system is housed in the handle for an easy and comfortable grip. The blades operate on lever switch rods that are both independent of each other so you can engage one or both depending on your preference.

Compared to other mowers, the new levers make it easier for people to use. The handles are positioned at different heights, and the downward angle from their tips makes it easy for people to position their hands on them.

The speed range on the mower is just right. It allows us to go slow when cutting really thick patches of grass and fast when cutting the lightest grass in the yard. The 25-inch version of this lawn mower has a back wheel feature that does not disengage when you release the drive levers. You need to push it forward a bit to unlock them.

We think it’s better that the mower is set to 3 inches on the deck height. This gives us a range of light to moderately thick grass, but still keeps the RPMs high enough for consistent cutting. We decided to kick it into Turbo and there were parts of the gully we knew people would want us to pass.

We were able to cut for about 35 minutes before the first battery switch, which took us about an hour and a half of runtime. The second battery took us about exactly 1 hour and 4 minutes, which was slightly longer than the estimate of more than 60 minutes from Greenworks.

Cutting Quality

No matter what type of yard you have, Greenworks packs everything that you need. They are effective at mulching and bagging, and they have a Turbo mode for improved productivity. The side discharge on the mower seems to remove most of the grass but leaves a lot of clippings within a few feet.

Consider switching out the stock blade with the Greenworks high-lift blade. The runtime will drop significantly, but you’ll get a lot more efficient bagging and mulching. For most lawns of 1/4 acre or less, swapping out the blades is recommended. You won’t need any additional batteries to finish the job on one set.

The blade helps with cutting evenness. With the high-lift blade, we were able to cut through a broader group of hair types efficiently and with fewer stragglers.

The results have been perfect and it’s no disappointment, but more improvements could be made to improve the quality.

Price and Availability

The Greenworks Pro 60V 21-inch self-propelled lawn mower is available at Tractor Supply or direct from Greenworks. You get a mowing machine with two 4.0Ah batteries and a dual-port rapid charger for $599.99 that has a four-year warranty on both the mower and the batteries.

Final Verdict

The design of the self-propelled mower by Greenworks is quite nice and it is a good option for most people, though some may find the wheel release back up to be difficult. The 2 x 4.0Ah kit is a good option for portable power that can get into tight spaces and is great for long-term equipment use. The 25-inch model is another option that many people use to charge batteries quickly and efficiently.
