Keenstone Cordless Lawn Mower 17in - Dual Battery Brushless

In this review the Keenstone Cordless Lawn Mower proves to be a practical choice for homeowners with small to mid-size yards who want a quiet, low-maintenance mowing option. The single biggest reason to buy is its direct-drive brushless motor, which delivers noticeably more torque in thick grass without the fuss of gasoline or routine engine maintenance. For anyone who values less noise, simple storage and a reliable dual-battery runtime, this mower strikes a useful balance between power and convenience.

Key Features

• Direct-drive brushless motor: The 18,000 RPM brushless motor transfers power straight to the blade for stronger cutting performance in dense turf and reduced mechanical wear over time.
• Dual-battery runtime: Two 20V 4.0Ah batteries provide about 35 minutes of continuous run time, enough to mow roughly a 1,500 sq ft yard on a single charge.
• 17in cutting width: A wider deck covers more ground per pass, shortening mow time and making the mower useful for small lawns that would otherwise take longer with narrower units.
• Large 10.5 gal collection bag: The high-capacity bag captures more clippings per load so you empty it less often when dealing with overgrown or high-volume grass.
• 6 height adjustments and 2-in-1 system: The lever adjusts cut height from 1in to 3in across six settings and converts between bagging and mulching without tools for seasonal flexibility.
• Compact, foldable handle: The three-position-adjustable handle accommodates users from about 4 ft 11 in to 6 ft 5 in and folds to a 15in depth for tidy garage shelf storage.

Who It's For

The Keenstone mower is best for homeowners with yards up to about 1,500 sq ft, people who prefer a push mower that is cordless and low maintenance, and anyone dealing with thicker grasses where a stronger torque delivery helps get an even cut. It is a solid pick for those who value quieter operation and the convenience of a two-battery system with rapid charging.

Shoppers with very large properties, commercial mowing needs, or who require walk-behind mowers with self-propel features should look elsewhere; this model is balanced for residential use and manual push operation rather than heavy commercial workloads.
