Summary
If you want power and strength the Greenworks PRO 21-Inch 80V Cordless Lawn Mower has what you need. The run-time is up to 1 hour so this is ideal for larger yards with a fair amount of lawn. The battery is also quick to charge. The 20-inch blade will make mowing the area fast and efficient. It also features a brushless and digitally controlled motor for maximum efficiency.
There are 2 options available. The GLM801601 comes with Two 2.0AH Batteries and the GLM801602 comes with a 4.0 AH Battery. It can also be purchased as a Tool Only option if you already have compatible batteries from other Greenworks 80V products.
Main Features
- A strong 80V rating
- Good 1 hour run time
- The powerful brushless motor is digitally controlled
- 21-Inch Deck
Power System
The digitally controlled brushless motor combined with the 80V delivers a powerful mowing ability that can handle larger areas and tough conditions. As cordless lawnmowers go, this is certainly one of the more powerful options.
According to the manufacturer, the power is equivalent to that of a 160cc gas engine. The Smart Cut(TM) Load sensing technology makes the lawnmower even more effective and efficient.
The Greenworks PRO 21 inch 80V is available with a choice of three configurations as shown below.
2 x 2Ah Batteries – Model Number GLM801601
1 x 4Ah Batteries – Model Number GLM801602
No Battery (tool only) – Model Number GLM801600
Assembly
The mower comes almost completely assembled. There is some minor assembly required which relates mostly to the handles. There are no complaints about this being difficult or time-consuming.
Blades
The Pro 21 has a 21-inch steel deck with a single 20-inch blade.
Height Adjustment
Height is easy to adjust with a single lever. It offers 7 height options from 1 1/4″ through to 3 5/8″. This versatility should provide more than enough options for most requirements. Given the great power of the mower, some might want a slightly higher maximum option for when the grass has been left to grow a bit long.
Cutting Diameter
You will achieve a 20-inch cutting diameter with this model.
Roller (Stripes)
The Greenworks PRO 21-Inch 80V Cordless Lawn Mower cannot make stripes on your lawn as it does not have a rear roller.
Grass box capacity
The capacity of the grass bag is a decent 13 US gallons (about 50 liters).
Safety Features
This model does not have advanced safety features. Provided it is used as directed and due caution is exercised it is a safe lawnmower to use.
The charger has a feature that will activate the built-in fan if the battery becomes too hot during charging. This will prolong the life of the battery but will slow charging down slightly.
Mulching
This lawnmower has 3 options which are mulching, a rear grass bag or side discharge. All are handy depending on the length of the lawn and your goals. Mulching is highly beneficial and will return valuable nutrients to the soil. These will enhance the health of the lawn and save you time and money. It is only practical when mowing frequently and will not work well if the grass is long.
