Black+Decker LHT321FF 20V MAX Lithium Hedge Trimmer Review

My Rating:​​​​​

A beautiful lawn is something to be proud, and while most homeowners want one, they don’t love the amount of maintenance and effort it requires to maintain a beautiful landscaping. Investing in a quality lawn mower is an obvious necessity, but it is often the lesser known accessories that assist us in achieving landscaping perfection.

Enter the Black+Decker LHT321FF 20V MAX Lithium PowerCommand Powercut Hedge Trimmer. 

The biggest advantage that this hedge trimmer has to offer is the fact that it’s cordless, backed by a 20V lithium-ion battery. Lithium-ion batteries offer a dearth of advantages, particularly when it comes to yard tools. Moreover, this hedge trimmer is just convenient to use and has a comfortable, ergonomic design. Thanks to this careful product engineering, shaping shrubbery and pruning your hedges will become second nature in no time.

Weighing in at only 7.9 pounds, the Black+Decker LHT321FF 20V MAX Lithium PowerCommand Powercut Hedge Trimmer can be comfortably carried around for extended periods of time. Because it is cordless, there are no limits on where you can take it. The powerful 20V lithium-ion battery offers portability without sacrificing run time. The surprisingly long battery life will enable you to edge trim, make vertical cuts, etc. on a single charge.

The front handle features a wraparound design that is a boost to this hedge trimmer. Not only does it offer a superb grip, but it makes the tool particularly easy to maneuver. To get started, all you need to do is pop in the batteries, pull the trigger to start the engine, and start attacking your overgrown hedges. The start button was created with a locking position, which eliminates the need to continuously hold it down. This both makes the trimmer easier to use and serves as a safety feature.

The dual action blades measure 22 inches in length, and according to the Black+Decker website, put off 40% fewer vibrations than other electric trimmers in the same class. It can tackle branches that are up to ¾” in diameter. The handy POWERCUT button, when pressed, provides an extra surge of power to cut through particularly tough shrubs and branches.

A purchase of the Black+Decker LHT321FF includes one 40V lithium-ion battery, and an Energy Star rated battery charger. On average, the charger will fully power up the battery in just under an hour. This hedge trimmer is backed by a limited, two-year warranty from the manufacturer.
