PowerSmart DB8621P Review

On paper the DB8621P is a bargain 21-inch push mower with a large 15.8-gal bag and 3-in-1 flexibility. Missing spec detail and an unstated warranty are the main drawbacks.

DB8621P review

PowerSmart DB8621P overview

The DB8621P is a 21-inch gas push mower from PowerSmart, a budget-focused brand that sells mostly online. It is a plain walk-behind: you provide the forward motion, and the machine offers three discharge modes (mulch, side and rear bag) in one deck. This PowerSmart DB8621P review is based on the maker’s product page and retailer listings, not hands-on testing.

One naming quirk is worth knowing. PowerSmart’s own page lists the model as DB8621P but uses a web address that says v8621p, and Lowe’s sells a closely related B8621P with a 140 cc Briggs and Stratton engine. Treat those as relatives, not identical machines.

Engine and drive

PowerSmart lists a 144 cc gas engine. The page we read does not name the engine maker, rated horsepower, starting method or fuel tank size, so we leave those out rather than guess.

There is no self-propel system. PowerSmart’s own range sorts this one under push mowers, and its self-propelled 21-inch sibling is the DB8621S. If your yard has slopes or you dislike pushing, that is the model to compare.

Deck and cutting

The deck is listed as ST14 steel and is 21 inches wide. Cutting height runs from 1.5 to 3.9 inches. A bag is included with a stated capacity of 15.8 gallons, which is roomy for a mower at this size.

Because the deck is steel rather than aluminum or poly, expect to rinse and dry it after wet grass to slow rust.

Size and who it suits

The maker does not publish a weight or wheel size for this model on the page we read. A Lowe’s listing for the B8621P cites 63 lb, which gives a rough idea of the class but may not match the DB8621P exactly.

PowerSmart lists the mower at $269.99 on sale, down from $299.99.

Warranty and buying advice

The product page links to a separate warranty page instead of stating terms, so confirm coverage before buying. For comparison, PowerSmart’s DB2321SR page states a 3-year limited warranty, but we cannot assume the DB8621P matches.

Pick the DB8621P if your lawn is small and flat and you want the lowest outlay. Skip it if you want a named engine brand printed on the spec sheet or a self-propel drive.

Buying information

Price

$269.99

Sale price seen on powersmartusa.com, Oct 2026 (regular $299.99). Retailer prices vary.

Where to buy

Warranty

PowerSmart's product page does not state the terms and links to a separate warranty page. Verify before purchase.

Depreciation and resale

No published resale figures. Low new price means used values are likely modest.

Ownership

Common problems

Spec-based limits: this model has no drive system, and PowerSmart's page leaves out engine brand, fuel capacity, weight and warranty. A Lowe's B8621P listing shows different engine and height figures, so related PowerSmart model numbers should not be mixed up.

Maintenance

Routine items only: engine oil, air filter, spark plug and blade sharpening, plus cleaning grass from under the steel deck.
