Whip Your Lawn Into Shape with the HART 21-Inch Self-Propelled Lawn Mower
Spring is here, and it’s time to give your lawn the care it deserves. The HART 21-Inch Self-Propelled Lawn Mower is an upgrade from its predecessor, promising even better performance. In this review, we’ll see if it’s the right choice for your lawn.
Pros and Cons
The HART 21-Inch Self-Propelled Lawn Mower showcases excellent cut quality.
Conveniently foldable handles allow for easy vertical storage.
This mower offers versatility with options for bagging, covering, or side discharge.
Adjusting the cutting height is a breeze thanks to the single-point height adjustment feature.
The power boost mode provides short bursts of extra power for tackling dense grass.
While the grip is comfortable, we would have preferred the presence bar embedded in the handle.
The drive speed slider can be prone to accidental activation.
Equipped with a powerful brushless motor, the HART 21-Inch Self-Propelled Lawn Mower effortlessly cuts through thick St. Augustine grass. Its temporary power boost feature allows for extra strength when encountering tough patches. Simply press the blade activation button again, and the mower enters a high-power state for approximately six seconds.
While it may not match the performance of the best battery-operated mowers, it outperforms most gas-powered 140cc models.
The HART 21-Inch Self-Propelled Lawn Mower offers three discharge options that cater to your preferences. With a true side discharge system, it efficiently distributes cuttings several feet beyond your mowing path. The mulching capability is satisfactory, comparable to higher-end mowers.
Additionally, its high airflow ensures impressive bagging performance for a battery-operated mower.
Looking back at the grass we mowed, we were pleased with the overall cut’s uniformity. Aside from some blades sticking together, the results showed significant improvement.
The HART 21-Inch Self-Propelled Lawn Mower features two active battery bays. However, it doesn’t have automatic battery switching. When one battery is depleted, you need to flip the red key under the cover to restart the mower and keep going. For smaller lawns, running the mower on just one battery is sufficient.
Under optimal conditions, HART estimates the mower can cover up to 3/4 of an acre on a single charge. We tested it with moderate maintenance cuts in dry weather, at around 90°F. Using the two included 6.0Ah batteries, we achieved a total run time of 50 minutes and 57 seconds. While HART’s estimate may be ambitious, achieving half an acre is certainly possible.
