How it works

There are a few unique features on the Greenworks 20-inch 40v Twin Force Cordless Lawn Mower with batteries that really give it an advantage over the competition.

Dual blades

Instead of having one 20-inch blade, this machine has two 10-inch blades. This allows the blades to turn faster with less power than larger blades, which gives your grass a smooth cut on the first pass, and allows the mower to run longer on a single charge.

Dual batteries

The Greenworks 20-inch 40v Twin Force Cordless Lawn Mower with batteries has two batteries with two battery ports. The mower will automatically draw power from the big battery (4 Ah) first. Then, when that battery starts to get depleted, the mower will automatically switch to the second, smaller (2 Ah) battery. This system will allow you to cut for up to an hour (slightly less if your lawn is more overgrown), and maintain full power for the entire duration of the mow.

SMARTCUT Technology

This mower also includes Greenworks’ SMARTCUT technology, which increases power to the blades when the mower encounters taller or thicker grass. This will help you achieve a smooth cut and avoid clogging the grass chute. Plus, this also means that the mower uses less power when the grass is shorter, which extends the time you can mow on a single charge of the dual batteries.

Ongoing use and maintenance

Maintaining your Greenworks 20-inch 40v Twin Force Cordless Lawn Mower with batteries is super easy. After each mow, you should clean the mowing deck of excess grass debris. Be sure to remove the key and batteries before doing any work under the cutting deck.

The lawn mower can be stored in any dry area, but it is best to keep the batteries inside so they don’t freeze in winter or get too hot in summer.

The large battery requires two hours on the charger to get fully charged, and the small batter requires one hour. So, you will want to plan to charge those batteries fully prior to each mow.

The blades should be sharpened and balanced each year.

Warranties

Greenworks provides a two-year battery warranty, and a four-year warranty on the rest of the mower.
