Overview of the Products

The Greenworks 80V 21” Brushless and the SKIL PWR CORE 40 Brushless 40V present two distinct approaches to lawn care. Priced at $499.99, the Greenworks offers a comprehensive combo kit, while the SKIL comes at a lower price of $349.00, making it about 30% cheaper. Both products cater to the needs of homeowners, but their functionalities and features differ significantly.

Power and Performance

Power is a key factor in lawn mowers, and both models deliver efficient performance. The Greenworks features an 80V brushless motor, designed for robust yard maintenance. In contrast, the SKIL employs a 40V digital brushless motor, which still provides high-performance power but at a lower voltage. With the included 6.0Ah battery, the SKIL can run for up to 50 minutes on a single charge, whereas the Greenworks kit includes two 2Ah batteries, which can be swapped for extended use. However, the Greenworks does not specify runtime, making it challenging to compare directly.

Design and Usability

When it comes to design and usability, the SKIL mower has an edge with its self-propelled feature, allowing users to adjust the speed based on their needs. The Greenworks, on the other hand, is a push mower, requiring more effort from the user. While both mowers offer adjustable height settings, the SKIL provides a single-lever adjustment with seven settings to quickly change cutting heights between 1.5 to 4 inches. This feature enhances user convenience, making the SKIL more user-friendly for a variety of grass types.

Versatility in Lawn Care

Versatility is crucial for lawn maintenance, and both products excel in this area. The Greenworks kit boasts a 3-in-1 system for mulching, bagging, and side discharge, providing homeowners with multiple options for handling grass clippings. Meanwhile, the SKIL also offers 3-in-1 functionality, allowing users to bag, mulch, or rear-discharge clippings. While both products accommodate various lawn care preferences, the Greenworks includes additional tools like a blower and a string trimmer, making it a more comprehensive package for tackling different lawn tasks.

Battery and Charging

The battery setup is a significant consideration for cordless electric mowers. The Greenworks includes two 2Ah batteries and a rapid 4A charger, ensuring quick replenishment for extended use. In comparison, the SKIL comes with a single 6.0Ah battery and an Auto PWR JUMP charger, which allows for convenient recharging. Although the SKIL's battery offers a longer runtime, the Greenworks provides multiple batteries, which can be a deciding factor for those with larger lawns that require more extended operation without interruptions.

Maintenance and Durability

Both mowers feature durable construction, but the SKIL is designed with weather-resistant materials, enhancing its longevity and performance even in adverse conditions. This feature may appeal to users who often mow in less-than-ideal weather. The Greenworks does not specify weather resistance, focusing instead on its robust build quality. Additionally, the SKIL’s telescoping handle allows for convenient vertical storage, making it easier to store in tight spaces compared to the Greenworks, which does not highlight this aspect.

Warranty and Customer Support

Warranty offerings can significantly impact the decision-making process for consumers. The Greenworks kit includes a generous 4-year warranty, providing added peace of mind for buyers. The SKIL’s warranty details are not mentioned, which may raise questions for potential users about long-term support. A more extended warranty often indicates a manufacturer's confidence in their product's durability, making the Greenworks a potentially safer investment for those concerned about longevity.

Which should you buy?

Choosing between the Greenworks 80V 21” Brushless and the SKIL PWR CORE 40 Brushless 40V largely depends on your specific lawn care needs and budget. The Greenworks, while more expensive at $499.99, offers a comprehensive toolset, including a mower, blower, and string trimmer, along with a longer warranty. In contrast, the SKIL is about 30% cheaper at $349.00 and provides excellent performance with its self-propelled feature and longer runtime. If you prioritize a complete lawn care package and warranty, the Greenworks may be the better choice. However, if budget and ease of use are your main considerations, the SKIL offers great value with reliable performance.
