Overview

The PowerSmart Self Propelled Gas Lawn Mower and the STEELITE 40V Electric Lawn Mower are both competitive options in the lawn care market, with distinct features catering to different user needs. While the PowerSmart mower is priced at $339.99, the STEELITE mower is slightly cheaper at $329.99, making it about 3% less expensive. Each product targets different lawn maintenance preferences, with the PowerSmart focusing on gas power and self-propulsion, while the STEELITE emphasizes electric convenience and multi-functionality.

Power Source

PowerSmart’s Self Propelled Gas Lawn Mower is equipped with a 170cc OHV 4-Cycle Engine, designed for effective cutting power and ease of starting. This gas-powered mower is ideal for those who prefer traditional fuel options and require a robust engine for tougher terrains. In contrast, the STEELITE Electric Lawn Mower operates with dual 20V 4.0Ah batteries, offering a runtime of up to 25 minutes. While the electric mower avoids the hassle of gas and oil, it may require more frequent recharging, particularly for larger yards.

Cutting Performance

When it comes to cutting performance, the PowerSmart mower features a rugged 21-inch steel deck and a superior mulching blade, which enhances its capability to handle grass efficiently. The mower also offers adjustable heights from 1.18 to 3 inches, accommodating various lawn heights. On the other hand, the STEELITE mower has a slightly smaller 17-inch cutting deck, which can be adjusted from 0.98 to 2.95 inches. While both models allow for mulching, the PowerSmart's broader deck means it can cover more ground quickly, making it potentially more effective for larger areas.

Weight and Maneuverability

The PowerSmart mower weighs in at 54 lbs, which may be more cumbersome for some users, especially in tight spaces. However, its self-propelled rear-wheel-drive system aids in maneuverability on inclined terrains and uneven ground. Conversely, the STEELITE mower is lightweight at only 30 lbs, making it remarkably easy to handle and maneuver around obstacles. Its user-friendly design, including instant start capabilities with a button push, adds to its appeal for those who prefer convenience over the physical exertion required by heavier mowers.

Versatility

Versatility is a strong suit for both mowers, though they excel in different areas. The PowerSmart mower offers 3-in-1 functionality, allowing users to mulch, side-discharge, or rear-bag grass clippings, along with a generous 1.4-bushel capacity grass bag to minimize interruptions during mowing. In contrast, the STEELITE mower also provides a 2-in-1 option for bagging and mulching while including a powerful string trimmer and a leaf blower in its combo package. This makes the STEELITE set exceptionally versatile for those looking to tackle multiple yard tasks with one purchase.

Storage and Maintenance

Storage and maintenance needs differ significantly between the two models. The PowerSmart mower features a foldable design that saves 70% in storage space, making it convenient for users with limited storage capacity. Maintenance for gas mowers like the PowerSmart requires more attention, including oil changes and winterization. The STEELITE mower, being electric, requires less maintenance and no oil changes, allowing users to focus more on mowing rather than upkeep. Its compact build further simplifies storage and transport, appealing to urban dwellers or those with smaller yards.

Cost of Ownership

In terms of initial cost, the PowerSmart mower is listed at $339.99, while the STEELITE mower is priced at $329.99, making the latter about $10 cheaper. However, it's essential to consider long-term costs as well. Gas mowers typically incur fuel and maintenance costs, while electric mowers may have lower operating costs without the need for fuel and oil. Therefore, while the upfront price difference is minimal, the ongoing expenses may favor the STEELITE mower for budget-conscious consumers.

Which should you buy?

Choosing between the PowerSmart Self Propelled Gas Lawn Mower and the STEELITE 40V Electric Lawn Mower ultimately depends on your specific lawn care needs. If you have a larger yard with varying terrains and prefer the power and cutting efficiency of a gas mower, the PowerSmart might be the better choice for you. However, if you seek a lightweight, easy-to-use mower that comes with additional tools for yard maintenance and lower maintenance demands, the STEELITE set would likely be more suitable. Consider your lawn size, terrain type, and maintenance preferences to make an informed decision.
