Dimension comparison
Price Comparison
The EGO POWER+ Electric Lawn Mower is about 91% more expensive than the PowerSmart Gas Lawn Mower. At $649.00, it costs $309.01 more than the PowerSmart model priced at $339.99. This significant price gap reflects the advanced electric technology and battery system in the EGO model, while the PowerSmart mower offers a budget-friendly entry point for those seeking basic gas-powered performance.
Performance and Power Source
The EGO POWER+ uses a brushless motor powered by a 56V 7.5Ah ARC Lithium battery, delivering over 60 minutes of run time on a single charge. In contrast, the PowerSmart relies on a 170cc OHV 4-cycle engine with a recoil starter and auto choke, designed for consistent power output across varied terrain. The EGO’s electric system eliminates fuel dependency and emissions, while the PowerSmart’s gas engine provides continuous power without recharging needs during extended use.
Cutting Technology and Versatility
The EGO POWER+ features a Select Cut Multi-blade System with three interchangeable lower blades—Mulching, High Lift Bagging, and Extended Runtime—each optimized for specific mowing tasks. It also includes an EGO Upper Blade that works with any lower blade to enhance cutting precision. The PowerSmart offers a standard 3-in-1 function (mulch, side discharge, rear bagging) with a single mulching blade, but lacks blade interchangeability or advanced cutting system integration. Both models support multiple cutting modes, but the EGO’s modular blade system provides greater adaptability.
Self-Propelled Functionality
The EGO POWER+ employs Touch Drive self-propelled technology, allowing variable speed control via fingertip pressure on the handlebar, with speeds ranging from 0.9 MPH to 3.1 MPH. This gives users intuitive, responsive control. The PowerSmart uses a rear-wheel-drive (RWD) system with a fixed speed of 3.5–4.1 km/h (approximately 2.2–2.5 MPH), offering less precise speed adjustment. While both provide self-propulsion, the EGO’s touch-sensitive system offers superior user control compared to the PowerSmart’s fixed-speed mechanism.
Battery and Charging
The EGO POWER+ includes a 56V 7.5Ah ARC Lithium battery and a rapid charger, enabling a full charge in just 60 minutes. This allows for quick turnaround between mowing sessions. The PowerSmart has no battery—it runs entirely on gasoline, requiring regular refueling and oil changes. There is no mention of charging time or battery life in the PowerSmart’s specs, as it operates independently of electrical systems.
Mowing Height Adjustments
Both mowers offer adjustable cutting heights, but with different ranges and mechanisms. The EGO POWER+ provides 7-position adjustments from 1.5 inches to 4 inches, allowing fine-tuned height control across diverse lawn conditions. The PowerSmart offers 6-position adjustments from 1.5 inches to 3.9 inches, slightly narrower in range. The EGO’s additional height setting provides more flexibility for seasonal lawn care routines.
Design and Portability
The PowerSmart features a foldable design that saves up to 70% of storage space, making it easier to store in tight areas like garages or sheds. Its compact build and 54-pound weight make it manageable for small to medium yards. The EGO POWER+ does not mention foldability or weight, though its cordless design implies portability. However, the absence of foldable details suggests it may be bulkier and less space-efficient than the PowerSmart.
Which should you buy?
Choose the EGO POWER+ Electric Lawn Mower if you prioritize zero emissions, quiet operation, low maintenance, and advanced cutting versatility—especially if your yard requires precise, high-quality results and you value long runtime on a single charge. It’s ideal for homeowners who want a premium, eco-conscious tool with smart features like touch drive and interchangeable blades. Opt for the PowerSmart Self-Propelled Gas Lawn Mower if you’re on a tighter budget, need a reliable, straightforward gas-powered mower for smaller yards, and prefer not to manage batteries or chargers. At $339.99, it’s about 48% cheaper than the EGO model and delivers solid performance for basic mowing tasks.
