STEELITE 21V 13-Inch Brushless Electric vs STEELITE 40V 17-inch Electric Lawn

Design and Build Quality

The Steelite 21V 13-Inch Brushless Electric is engineered for compactness, weighing only 20.5 lbs. This lightweight construction makes it accessible for users who may struggle with heavier machinery. The build focuses on simplicity, with a foldable handle designed for hassle-free storage. In contrast, the STEELITE 40V 17-inch Electric Lawn weighs 30 lbs, reflecting its larger deck and dual-battery system. Both models utilize durable materials suitable for residential use, but the heavier build of the 40V model suggests a sturdier frame capable of handling tougher terrain.

Cutting Deck and Width

Cutting width is a primary differentiator between these two units. The Steelite 21V 13-Inch Brushless Electric features a 13-inch deck, making it ideal for small yards, slopes, and tight spaces where maneuverability is key. The STEELITE 40V 17-inch Electric Lawn expands this coverage with a 17-inch deck. This 4-inch difference allows the 40V model to cover more ground per pass, reducing the total time required to mow mid-sized lawns. Users with larger properties will find the wider deck of the 40V model more efficient.

Motor Performance and Power

Both lawn mowers utilize brushless motor technology, which offers longer lifespans and reduced maintenance compared to brushed alternatives. The Steelite 21V 13-Inch Brushless Electric delivers strong torque suitable for its compact size. The STEELITE 40V 17-inch Electric Lawn specifies a 3400 RPM high-efficiency brushless motor powered by dual 20V 4.0Ah batteries. This configuration provides stronger cutting power, capable of handling thicker grass conditions more effectively than the single battery 21V system.

Battery Life and Efficiency

Runtime is comparable between the two models despite the difference in voltage. The Steelite 21V 13-Inch Brushless Electric offers up to 25 minutes of runtime on a single 21V 4.0Ah battery. The STEELITE 40V 17-inch Electric Lawn also delivers up to 25 minutes of runtime, depending on grass conditions and terrain, using its dual-battery setup. While the runtime is similar, the 40V model maintains this performance while driving a larger blade. Both units support extended runtime options, with the 21V model offering a 50-minute version with two batteries.

Height Adjustment Options

Adjustability allows users to customize their lawn's appearance. The Steelite 21V 13-Inch Brushless Electric features a 5-level height adjustment system, ranging from 0.98 inches to 2.56 inches. Adjustments are made with one touch and require no tools. The STEELITE 40V 17-inch Electric Lawn offers a 6-position cutting height adjustment, ranging from 0.98 inches to 2.95 inches. The single lever design on the 40V model allows for rapid changes, providing a slightly higher maximum cut for overgrown grass.

Grass Collection and Mulching

Both mowers support a 2-in-1 design for bagging and mulching. The Steelite 21V 13-Inch Brushless Electric includes an 8-gallon grass bag for clean collection. Users can detach the bag for natural mulching. The STEELITE 40V 17-inch Electric Lawn includes a 40L collection bag, which offers greater capacity before needing to be emptied. It also includes a mulch plug to turn clippings into natural lawn nutrition. The larger bag capacity on the 40V model reduces interruption during mowing sessions.

Portability and Storage

Portability is a strong suit for the Steelite 21V 13-Inch Brushless Electric. At 20.5 lbs, it is easy to lift, steer, and store, making it perfect for users who need to transport the mower frequently or store it in small spaces. The STEELITE 40V 17-inch Electric Lawn weighs 30 lbs but still features a foldable handle and compact build for hassle-free storage. While heavier, the 40V model remains manageable for most users, though the 21V model holds a distinct advantage for those prioritizing minimal weight.

Price and Value

The price difference is significant between these two options. The Steelite 21V 13-Inch Brushless Electric is priced at $139.99, offering an affordable entry point for cordless mowing. The STEELITE 40V 17-inch Electric Lawn is priced at $329.99, reflecting its larger deck, dual batteries, and higher power output. For small yards and budget-conscious buyers, the 21V model provides excellent value. For those needing more power and capacity, the 40V model justifies its higher cost with enhanced performance specifications.
