Performance and Power
Power and performance are essential in lawn care equipment, and both the PowerSmart mower and Sun Joe dethatcher deliver in their respective functions. The PowerSmart mower is equipped with a 144cc OHV engine, providing impressive power for cutting grass and maintaining a clean finish. This engine ensures that the mower can handle various grass types and conditions effectively.

This feature is particularly beneficial for those looking to improve lawn aeration and growth. While the PowerSmart mower is focused on cutting, the Sun Joe's motor is tailored for lawn rejuvenation, making each product optimal for its specific purpose.
Cutting and Dethatching Capabilities
The cutting capabilities of the PowerSmart mower are diverse, featuring a 2-in-1 design that allows for mulching and rear bagging. This versatility makes it suitable for various lawn care preferences, whether one prefers to return nutrients to the soil through mulching or collect clippings for easy disposal.

However, its design focuses on efficiency in dethatching, making it a reliable tool for those who prioritize lawn health over cutting grass.
Safety Features
Safety is paramount in lawn care equipment, and the PowerSmart mower includes a start/stop control lever for immediate stopping. This feature ensures that users can quickly halt the mower in case of emergencies, providing peace of mind during operation. Such safety measures are essential when operating powerful machinery.
The Sun Joe dethatcher also emphasizes user safety with its electric design, which eliminates the need for gasoline and reduces the risk of spills and fumes. While it may not offer the same immediate stopping feature as the PowerSmart mower, its electric motor provides a safer alternative for those concerned about hazardous materials.

Both the PowerSmart mower and Sun Joe dethatcher offer convenient cleanup options. The PowerSmart mower's rear bagging system makes it easy to collect clippings, allowing for quick disposal and a cleaner lawn appearance. This feature is particularly beneficial for users who prefer a tidy yard without leaving grass clippings behind.
In comparison, the Sun Joe dethatcher comes with an 8-gallon detachable collection bag that efficiently gathers thatch and debris.

The significant cost savings of about 50% make the Sun Joe an attractive choice for budget-conscious consumers or those with specific lawn care needs.
Which should you buy?
Deciding between the PowerSmart 21" Push Lawn Mower and the Sun Joe Corded Electric Dethatcher ultimately depends on your lawn care needs. If you require a reliable mower that offers versatility with mulching and bagging capabilities, the PowerSmart mower is a great choice due to its powerful engine and maneuverability.
