Product Description

The PowerSmart 21″ 144cc Gas Push Lawn Mower is a straightforward gasoline-powered walk-behind mower designed for residential lawn maintenance. The exact model used for this listing is the PowerSmart DV8621C, identified by manufacturer SKU DB8621C-101020371. It combines a 144cc gasoline engine, steel mower deck, push-drive layout, and six selectable cutting-height positions in a compact mowing platform.

Power comes from a 144cc gasoline engine equipped with recoil starting and an automatic-choke system. The mower does not use a self-propelled transmission; movement is controlled directly by the operator through its lightweight push configuration.

PowerSmart markets this mower in the 21-inch class, while its detailed specification table gives the actual cutting width as 20.5 inches. For ecommerce accuracy, “21-inch” can remain in the product title while the technical specification table should retain the manufacturer’s exact 20.5-inch cutting-width figure.

The mower provides a 2-in-1 mowing system supporting both mulching and side discharge. Mulching allows cut grass to be recirculated beneath the deck and reduced into smaller clippings, while the included side-discharge chute directs clippings away from the mower when that configuration is preferred. Rear bagging is not part of the advertised 2-in-1 configuration for this exact model.

Cutting height can be adjusted through six positions from 1.5 to 3.9 inches, allowing the mower to accommodate different maintained-grass heights and seasonal lawn conditions.

The mower uses a durable steel deck and a wheel configuration consisting of 7-inch front wheels and larger 10-inch rear wheels. The larger rear-wheel diameter can help the push mower roll across ordinary lawn surfaces while maintaining its simple manual-drive design.

PowerSmart lists the mower at approximately 63 lb., with shipping-package dimensions of 33.3 × 22.7 × 16.4 inches. The handle can also fold down to reduce the amount of storage space required in a garage or shed.

The mower is shipped approximately 95% pre-assembled, reducing the amount of setup required before initial use.

Engine Configuration

144cc Gas Engine

The DV8621C uses a:

144cc gasoline engine

with:

Recoil Start

and:

Automatic Choke

The automatic-choke system is designed to simplify normal starting without a separate manual choke-control procedure.

Drive Configuration

Push Drive

Drive Type: Push

This exact model is not self-propelled.

The user provides the forward movement while the gasoline engine powers the cutting blade.

Do not describe the DV8621C as rear-wheel drive or self-propelled; those specifications apply to other PowerSmart models such as the 170cc DB8621S.

Cutting Configuration

21-Inch Class Deck

PowerSmart markets this model as a:

21″ Gas Push Lawn Mower

while its technical table lists:

20.5″ Cutting Width.

Recommended Ecommerce Treatment

Product Title: 21″

Technical Cutting Width: 20.5″

This keeps the manufacturer-facing product name and detailed specification accurate at the same time.

2-in-1 Mowing Configuration

The exact DV8621C supports:

Mulching

Grass clippings remain beneath the cutting deck long enough to be reduced into smaller pieces before returning to the lawn.

Side Discharge

Clippings can be directed through the side-discharge opening using the supplied chute.

PowerSmart describes this exact mower as:

Mulching + Side Discharge

and not as a standard 3-in-1 rear-bagging model.

Cutting Height Configuration

6 Adjustable Positions

Minimum Cutting Height: 1.5 in.

Maximum Cutting Height: 3.9 in.

Adjustment Positions: 6

The selectable cutting-height range allows the deck to be adapted to different maintained lawn heights.

Wheel Configuration

Front Wheels

7 in.

Rear Wheels

10 in.

The larger rear wheels are paired with smaller front wheels in the mower’s manual push configuration.

Fuel Configuration

Fuel Tank Capacity: 0.21 U.S. gal.

Because this is a gasoline mower, fuel should be handled, stored, and used only according to the manufacturer’s operating manual and applicable safety requirements.

Engine Oil Configuration

Oil Capacity: 16.9 fl. oz.

Oil specification and maintenance intervals should follow the supplied PowerSmart manual rather than being inferred from other 144cc mower models.

Storage Configuration

The mower incorporates a:

Foldable Handle

which helps reduce its storage footprint when the mower is not being used.

Product Weight

63 lb.

This is PowerSmart’s current published weight for the DV8621C.

Package Dimensions

33.3 × 22.7 × 16.4 in.

These are shipping-package dimensions rather than fully assembled mower dimensions.

Assembly

PowerSmart describes the DV8621C as approximately:

95% Pre-Assembled

for simplified initial setup.

What’s Included

PowerSmart explicitly lists the following accessory/document contents:

• 1 × Side-discharge chute
• 2 × Cable clips
• 1 × User manual

The mower itself is the primary purchased product.

Not Included / Not Standard

Unless your exact retail package separately adds them, do not advertise the following as standard:

• Rear grass bagging system
• Self-propelled transmission
• Electric-start battery
• Spare blade
• Engine oil
• Mower cover
• Additional maintenance parts

This exact configuration is officially presented as a 2-in-1 mulching + side-discharge push mower.

Ideal Applications

The PowerSmart DV8621C is suitable for ordinary maintained residential lawn mowing where a manually pushed gasoline mower is appropriate, particularly:

• Small to medium residential lawns
• Flat or moderately varied lawn layouts
• Areas around landscaping
• Locations where compact mower storage is useful
• Lawns requiring selectable mowing heights
• Users who prefer mulching or side-discharge configurations
