The BLACK+DECKER LHT321 is a 20V MAX cordless hedge trimmer with a 22-inch dual-action blade, a 3/4-inch maximum cutting capacity, and a POWERCUT button designed to help clear a jam. The kit includes the LHT320 trimmer, a 1.5Ah battery, and a wall-mountable charging base.
Our verdict: The LHT321 is a practical residential choice for medium-size hedges when cordless mobility and jam-clearing convenience matter. Its 7.9-pound listed weight and slow included charger are the main tradeoffs. Buyers with lighter work should compare the lower-weight LHT2220, while frequent long sessions may justify a higher-capacity battery or another platform.
Research note: This is a research-based review. I have not personally tested this hedge trimmer. I checked BLACK+DECKER’s current product page, kit contents, battery specifications, warranty, and relevant alternatives on September 5, 2026.

LHT321, LHT320, and LHT321FF model names
BLACK+DECKER’s current product page calls the battery-and-charger kit LHT321 and identifies the included bare tool as LHT320. Some marketplace listings use the name LHT321FF. The most useful checks are the 22-inch POWERCUT tool, included 1.5Ah battery, included charger, and the seller’s exact package list.
Who should buy the LHT321?
- Good fit: medium-size residential hedge lines and shrubs.
- Good fit: properties where an extension cord would be awkward.
- Good fit: owners of compatible BLACK+DECKER 20V MAX tools.
- Good fit: users who value a button that helps clear an occasional blade jam.
- Look elsewhere: thick woody growth beyond 3/4 inch.
- Look elsewhere: very large jobs that require repeated charging.
- Look elsewhere: buyers who prioritize the lightest cordless trimmer.
What POWERCUT does
POWERCUT is designed to help the blade work through a jam when you press its button. It can be useful when a flexible twig or dense cluster stalls the normal cutting action. It does not increase the tool’s official 3/4-inch branch capacity, and it does not turn the trimmer into a substitute for loppers or a pruning saw.
If the blade remains stuck, release the trigger, remove the battery, and follow the manual before clearing debris. Do not hold the trigger or reach near the blade while troubleshooting a jam.
Blade length and cutting capacity
The 22-inch dual-action blade is a middle-ground size. It covers more hedge per pass than a short compact trimmer while remaining easier to place around shrubs than many 24- or 26-inch models. BLACK+DECKER says the dual-action design produces less vibration than its single-action blade models.
The official maximum branch capacity is 3/4 inch. Treat that as an upper limit. Dry, dead, or dense stems can be harder to cut than fresh growth of the same diameter. Use a dedicated pruning tool for isolated heavy branches instead of forcing the trimmer.
Battery coverage and charge time
BLACK+DECKER advertises up to 3,000 square feet of actual hedges per charge. That is a manufacturer benchmark rather than a guaranteed result. Hedge density, branch thickness, battery age, temperature, and the number of jams all affect real coverage.
The included LBXR20 battery is rated at 1.5Ah and 30Wh. The official page lists a 480-minute charge time with the included wall-mountable base. That is about eight hours, so the bundled charger is better suited to overnight charging than rapid turnaround. A compatible charged spare battery can reduce downtime, but verify battery and charger compatibility before buying accessories.
Weight and handling
BLACK+DECKER lists the LHT321 at 7.9 pounds. That is manageable for many users but not especially light for a 20V hedge trimmer. The ergonomic handle and soft-grip surfaces can improve control, but weight still matters when trimming tall hedge sides or holding the tool away from the body.
Work from stable ground, keep both hands on the tool, and avoid overreaching. For growth above a comfortable standing reach, use a purpose-built pole hedge trimmer rather than a ladder with a standard trimmer.
LHT321 vs LHT2220
| Feature | LHT321 | LHT2220 |
|---|---|---|
| Blade | 22 inches | 22 inches |
| Maximum capacity | 3/4 inch | 3/4 inch |
| Battery | 20V MAX, 1.5Ah included | 20V MAX, 1.5Ah included |
| Listed weight | 7.9 lb | 5.7 lb |
| POWERCUT | Yes | No |
The LHT321’s main advantage is POWERCUT. The LHT2220 has the same blade length and stated capacity at a considerably lower listed weight. Choose based on whether jam-clearing convenience is worth the extra weight for your hedges.

Frequently asked questions
Does the LHT321 include a battery and charger?
Yes. BLACK+DECKER currently lists an LBXR20 1.5Ah battery and LCS1620 charging base with the LHT321 kit.
What is the difference between LHT321 and LHT320?
LHT321 is the kit designation. BLACK+DECKER identifies the included trimmer as LHT320. Some retailers also use the LHT321FF suffix for a kit.
How thick a branch can it cut?
BLACK+DECKER lists a 3/4-inch maximum capacity. Use loppers or a pruning saw for larger, dead, or unusually dense stems.
How long does the battery last?
BLACK+DECKER describes coverage of up to 3,000 square feet of actual hedges per charge. Real results vary with the hedge, battery, temperature, and technique.
Is POWERCUT a higher-power mode?
It is a jam-clearing feature used at the push of a button. It does not change the published maximum branch capacity.
Final recommendation
Choose the BLACK+DECKER LHT321 when you want a 22-inch cordless trimmer and expect POWERCUT to be useful on flexible or dense hedge growth. Compare its 7.9-pound weight and slow included charger with the job you actually have. For routine light trimming, the LHT2220 may be easier to carry; for long sessions near an outlet, a corded model can avoid charging downtime.
