Buying Guide

Key Features to Look For

• Battery Power and Runtime: For this specific model, the dual 40V 4.0Ah batteries are a key selling point, offering extended runtime suitable for up to 1/4 acre. Always check battery voltage and amp-hour ratings to ensure they meet your lawn size needs.
• Cutting Width and Deck Material: A wider cutting deck, like the 21-inch steel deck on this PowerSmart mower, means fewer passes and quicker mowing. Steel decks are generally more durable than plastic.
• Height Adjustment System: Look for easy-to-use, single-lever adjustment with a good range of heights, typically from 1.5 to 4 inches, to accommodate different grass types and conditions.
• Mowing Functions: Consider whether you need mulching, bagging, or side-discharge capabilities, or a combination of these. This mower offers mulching and bagging.
• Motor Type: Brushless motors are more efficient, durable, and quieter than brushed motors or gas engines.

Important Materials

• The steel deck is a significant material consideration, indicating robustness and longevity for the cutting deck, which is exposed to grass, debris, and the elements.

Essential Factors to Consider

• Lawn Size: Accurately measure your lawn. The 1/4 acre coverage with two batteries is a crucial specification for this mower. If your lawn is significantly larger, you might need additional batteries or a different model.
• Terrain: While this is a push mower, consider if your lawn has steep slopes or many obstacles, which might influence maneuverability preferences.
• Grass Type and Thickness: The power of the motor and the sharpness of the blades will affect how well the mower handles thick or overgrown grass.
• Battery Compatibility: If you own other tools from the same brand and voltage, check if the batteries are interchangeable to potentially save on future purchases.

Budget Planning

• Cordless electric lawn mowers can range from a few hundred dollars to over a thousand, depending on features, battery capacity, and brand reputation. This PowerSmart 40V 21″ Cordless Lawn Mower, with its dual batteries and steel deck, likely falls into the mid-range, offering good value for its features. Consider the long-term savings on fuel and maintenance compared to gas mowers.

When to Buy

• The best time to purchase a lawn mower is often in the spring, as warmer weather approaches and lawn care becomes a priority. Retailers may offer promotions or sales to coincide with the start of mowing season. Buying before peak season can sometimes secure a better deal.
