The PowerSmart DB2321CR is a powerful gasoline-powered push mower that is designed to chew through wide swaths of grass in a single pass. The 170 CC four-stroke engine is exceptionally quiet for a gasoline motor and comes with a special forced-air cooling system to optimize performance.

It has a 21-inch diameter cutting deck with five easy to adjust height settings. This means you can set it as low as 1.18-inches when the grass is growing fast. You can then set it as high as 3-inches in dry times when preserving soil moisture is critical for preventing premature dormancy.

The PowerSmart DB2321CR is classified as a 2-in-1 gasoline-powered push mower. This means you can leave it set up for side discharge, or you can set it up as a mulching mower. It gives you the ability to minimize harvested grass clippings to prevent the build-up of turf-choking thatch.

It’s also worth noting that the PowerSmart DB2321CR is backed by a robust 3-year warranty, as well as a company that is dedicated to superior customer service. This is a real statement of confidence in material build quality and engineering.

Key Features

  • Air cooling system
  • 2-in-1 versatility
  • Side Discharge or mulching lawn mower
  • 21-inch diameter
  • 5 Height settings
  • 1.18 to 3-inches

There was a lot of thought put into the 170 CC four-stroke gasoline engine in the PowerSmart DB2321CR. Not only is it very powerful, which makes for a superior harvest rate and performance of the cutting blade, but the air-cooled 4 stroke engine is exceptionally quiet.

This can be a big benefit if you have neighbors nearby, but you still need a lawn mower with the power to chew through thick-bladed grass. It’s great for lawns with Bermuda or thick Kentucky Bluegrass.

If there is one minor complaint with the PowerSmart DB2321CR, it’s that the fuel tank will only hold .21 gallons of unleaded gasoline. It won’t be an issue if your yard is under a third of an acre or so. Though, you might have to stop to refuel if your lawn is half an acre or more.

Ease Of Use

The PowerSmart DB2321CR is relatively easy to use. The 8-inch wheels tend to move smoothly over most suburban lawns. The air cooled 170 CC four-stroke engine is quiet and easy to maintain. For what it’s worth the conversion to the mulching mower is even easier to make than a lot of the competitor lawn mowers.

Special Features

The air cooled 170 CC four-stroke gasoline engine in the PowerSmart DB2321CR provides power, performance and relatively quiet operation. You also have to like that it’s backed by a 3-year warranty and superior customer service.

The 2-in-1 functionality is also great for customizing the cut to the needs of your lawn. The tiny pieces of grass created by the mulching mower are more likely to decompose rather than dry out. This helps feed nitrogen back to the lawn rather than drying out into problematic thatch.

The 8-inch diameter wheels and the 58-pound weight might not seem like a special feature at first glance. Though they help the PowerSmart DB2321CR to be more nimble than a lot of other gasoline lawn mowers, which tend to be bulky due to the motor weight.

Cut Quality & Options

The PowerSmart DB2321CR lets you cut your lawn to the prevailing conditions in a few different ways. Right off the bat, the 5 cutting height settings let you set the length of the grass for the recent weather pattern. You can leave the grass as long as 3-inches for times when the weather has been dry and water restrictions prevent you from using the irrigation system. On the other end of the spectrum, you can dial the deck height down as low as 1.18-inches for times when a combination of sun and seasonal rain has the grass growing vigorously.

You can also appreciate the 2-in-1 versatility of the PowerSmart DB2321CR. It comes set up to side discharge the harvested grass clippings. This is great for times when you can cut the lawn frequently to leave behind modest pieces of thatch.

If your lawn has had thatch problems in the past, or it got a little long on you while on vacation, the mulching feature can be handy for minimizing the harvested clippings. Not only is mulching a great way to prevent thatch buildup in the upper layers of the turf, but tiny mulched pieces of grass decompose easily into the turf to help feed it with some organic nitrogen.


As a gasoline-powered lawn mower, the PowerSmart DB2321CR needs the usual maintenance of oil changes, air filter cleaning, and blade sharpening. Though PowerSmart did their best to make this relatively easy.

If you have to mow your lawn when the grass is slightly damp, or you have thick-bladed grass, you might want to double-check the underside of the 21-inch diameter cutting deck in case there is any stuck-on organic matter.

Safety Features

The PowerSmart DB2321CR comes with the standard safety hand controls that you find with a lot of gasoline-powered push mowers.


The PowerSmart DB2321CR is relatively cost-effective compared to a lot of the competitor’s gasoline-powered push mowers. The 170 CC four-stroke engine with its air cooling system not only helps optimize overall performance but also improves fuel efficiency while promoting long engine life.

You can also appreciate the way the 2-in-1 versatility and the adjustable cutting deck height help you set up the PowerSmart DB2321CR to produce minimal thatch. This translates into a reduced need for the cost of seasonal aeration, and might even help you save money on seasonal fertilizing.

The 3-year warranty that comes with the PowerSmart DB2321CR is also a statement of superior engineering and material build quality. Not only does it give you a
