Buying Guide
Key Features to Look For
When considering a cordless mower like the Greenworks 40V 16″ Cordless Lawn Mower, Ultra-Light Push Mower with 4.0Ah Battery & Charger(75+ Tool Compatibility, 45Min Runtime), pay close attention to battery runtime and charge time. The included 4.0Ah battery offers approximately 35 minutes of runtime, sufficient for many small to medium lawns, with a 2-hour recharge. Look for ease of use features such as a push-button start and adjustable cutting heights, like the 5-position lever on this model. Cutting deck width is also important; a 16-inch deck is maneuverable for smaller areas but might require more passes for larger lawns. Finally, consider the versatility of the battery system; Greenworks’ 40V platform, compatible with over 75 tools, offers great expandability.
Important Materials
While specific material breakdowns are not detailed in the provided features, cordless mowers typically utilize durable, lightweight plastics for the housing and deck, often combined with metal components for the blade assembly and structural elements. These materials are chosen to balance durability with the goal of keeping the mower as light as possible for ease of handling.
Essential Factors to Consider
The size of your lawn is paramount. The stated capability of this mower for yards up to ½ acre with its 35-minute runtime is a key consideration. If your lawn is significantly larger, you might need multiple batteries or a model with longer runtime. Consider your physical strength and comfort; the ultra-lightweight design (35% lighter) is a significant advantage for many users. Also, think about your existing or desired tool ecosystem; if you’re invested in Greenworks’ 40V system, this mower fits seamlessly. Assess your grass type and desired lawn height, as the 5-position height adjustment (1.25″-3.375″) caters to a range of needs.
Budget Planning
The price of a cordless mower varies significantly based on battery size, motor power, and brand reputation. This Greenworks model offers a good balance of features and performance for its category, especially when factoring in the included 4.0Ah battery and charger, and the potential cost savings from eliminating gas and oil. Expect to invest in high-quality cordless equipment, but recognize the long-term value in reduced running costs and maintenance. The annual savings of $200+ mentioned in the features highlight the potential return on investment.
When to Buy
The best time to buy a lawn mower is often in the spring as the mowing season begins, or in the fall as retailers clear out inventory. However, cordless mowers are gaining popularity year-round. Look for sales events like Memorial Day, Father’s Day, or holiday promotions. If your current mower is failing, don’t wait too long into the mowing season to replace it.
