Price Comparison
The BILT HARD 21 Inch Lawn Mower is priced at $359.99, making it about 17% cheaper than the Greenworks 80V 21" Self-Propelled Cordless Lawn Mower, which retails for $479.99. Price can be a significant factor for many homeowners when choosing a lawn mower. While the BILT HARD mower delivers good performance for its cost, the Greenworks model offers advanced features that justify its higher price. For those on a budget, the BILT HARD mower offers a solid, cost-effective solution. However, if you're willing to invest more for added convenience and technology, the Greenworks model may be the right choice.
Engine and Power Source
The BILT HARD mower features a powerful 201cc 4-stroke OHV engine that delivers efficient performance, while the Greenworks mower is powered by an 80V brushless motor. Each power source has its advantages; gas engines tend to provide longer run times and are effective for larger areas, while electric motors like the one in the Greenworks mower offer quieter operation and require less maintenance. The Greenworks mower is designed to cut up to 1/2 acre on a single charge, making it a great option for homeowners with medium to large lawns. In contrast, the BILT HARD mower's gas engine ensures reliable performance with no need for battery charging.
Cutting Versatility
Both mowers offer versatile cutting options, but they differ in their functionality. The BILT HARD mower features a 3-in-1 steel deck that allows for mulching, side discharge, and rear bagging, catering to various lawn care needs. The adjustable cutting height ranges from 1.2" to 3.75", giving users the ability to customize their mowing height. On the other hand, the Greenworks model also boasts a 4-in-1 cutting system, including mulching, bagging, side discharge, and turbo leaf pickup. This added functionality provides an edge for users looking to handle diverse lawn tasks effectively.
Ease of Use
The BILT HARD mower is designed with user-friendly features such as a no choke, no primer single-pull start, making it easy for anyone to operate. Its comfortable foam-wrapped angled grip and double ball-bearing wheels contribute to a smoother mowing experience. Conversely, the Greenworks mower's self-propelled design with rear wheel drive and variable speed control enhances user control, making it easier to maneuver around obstacles. Additionally, the inclusion of LED headlights allows for mowing in low-light conditions, further improving usability.
Maintenance and Longevity
In terms of maintenance, the BILT HARD gas mower requires regular engine maintenance, including oil changes and spark plug replacements. However, it benefits from the durability associated with gas-powered tools. The Greenworks mower, being cordless, minimizes maintenance needs since it does not require fuel, oil changes, or spark plug replacements. The brushless motor is designed for longer life and quieter operation, appealing to those who prioritize low upkeep. Both mowers come with warranties, but the Greenworks model emphasizes its compatibility with 75+ tools, offering a future-proof investment for homeowners looking to expand their outdoor equipment.
Performance and Efficiency
The performance of each mower caters to different user needs. The BILT HARD mower, with its robust engine delivering 9.0 ft.lb of torque, is geared towards those who have a larger lawn and need reliable power. Its sales rank of 23,345 indicates that it has a solid presence in the market. On the other hand, the Greenworks mower's brushless motor provides 30% more torque than standard models, enhancing its ability to tackle overgrown grass and uneven terrain. Its lower sales rank of 1,880 suggests it is well-regarded for its cutting-edge technology and efficiency.
Environmental Impact
When comparing environmental impact, the Greenworks mower stands out as the more eco-friendly option. It operates quietly and produces zero emissions, making it ideal for environmentally conscious consumers. In contrast, the BILT HARD gas mower, while effective, emits fumes and noise typical of gas-powered equipment. This difference may influence homeowners who prioritize sustainability and are looking to reduce their carbon footprint while maintaining their lawns.
Which should you buy?
Choosing between the BILT HARD 21 Inch Lawn Mower and the Greenworks 80V 21" Self-Propelled Cordless Lawn Mower ultimately depends on your specific lawn care needs and budget. If you're looking for a reliable, cost-effective option and don't mind the maintenance associated with gas engines, the BILT HARD model is a strong choice. Conversely, if you prefer a quieter, more versatile, and low-maintenance lawn mower with advanced features, the Greenworks mower justifies its higher price. Assess your lawn size, mowing preferences, and budget to make an informed decision that best suits your requirements.
