Overview
When it comes to lawn maintenance, both the PowerSmart Self Propelled Gas Lawn Mower and the WEN 20V Max Cordless Brushless Lawn Mower offer distinct advantages. The PowerSmart mower is priced at $339.99, while the WEN model is about 33% cheaper at $226.89. Each mower is designed for different preferences, whether you prefer gas or electric, making them suitable for various users.
Engine and Power Source
The PowerSmart mower is equipped with a 170cc OHV 4-cycle engine, providing robust power for efficient cutting. This gas-powered option is favored for its ability to handle tough terrain, particularly with its self-propelled rear-wheel drive system. In contrast, the WEN mower operates on a brushless motor powered by two 5Ah lithium-ion batteries, offering a cleaner alternative with no emissions. While the PowerSmart mower excels in raw power, the WEN model emphasizes ease of use and lower maintenance with its battery operation.
Cutting Performance
In terms of cutting performance, the PowerSmart mower boasts a 21-inch steel deck and a cutting height adjustable from 1.5 to 3.9 inches, allowing for a customizable mowing experience. The WEN mower features a slightly smaller 19-inch deck, but it still offers five height settings ranging from 1.5 to 3.2 inches. Both models are capable of mulching, but the PowerSmart's heavier construction might provide a more substantial cut, while the WEN's brushless motor ensures efficient operation without the need for gas.
Versatility and Features
PowerSmart's mower is designed for versatility with its 3-in-1 functionality, allowing users to mulch, side-discharge, or rear-bag grass clippings. Its 1.4-bushel capacity grass bag is easy to empty, which can save time during mowing sessions. On the other hand, the WEN mower also doubles as a mulcher and includes a collapsible handle for easy storage. While both offer similar functionalities, the PowerSmart's multiple options for grass disposal may appeal more to those looking for flexibility.
Ease of Use
The PowerSmart mower weighs 54 lbs and is described as easy to operate, particularly in tight spaces, thanks to its compact design. The self-propelled feature adds a level of convenience, especially on slopes. The WEN mower, being cordless, eliminates the hassle of fuel and oil, making it lightweight and easy to maneuver. Its inclusion of a collapsible handle further enhances its portability and ease of storage. Users who prioritize convenience might find the WEN model more appealing.
Maintenance
Maintenance varies significantly between the two models. The PowerSmart mower, with its gas engine, may require regular oil changes and spark plug replacements, which could increase upkeep time and costs. Conversely, the WEN mower's brushless motor requires less maintenance and promises a longer lifespan than traditional motors. This aspect makes the WEN mower an attractive option for those looking to minimize maintenance efforts and costs.
Runtime and Efficiency
The WEN mower can handle lawns up to 10,300 square feet on a single charge with the two included batteries, providing a runtime of 30 to 68 minutes depending on conditions. This efficiency is appealing for users with larger yards. The PowerSmart mower, while it does not rely on battery power, is not limited by runtime constraints but may require refueling during extended use. Thus, for users with larger properties, the WEN mower's battery life could be a significant advantage.
Pricing and Value
With the PowerSmart priced at $339.99 and the WEN model at $226.89, the WEN mower is about 33% cheaper. Despite the price difference, each mower offers unique value based on user needs. The PowerSmart mower may justify its higher price with robust features and performance, while the WEN mower provides a budget-friendly option with lower maintenance and environmental concerns. Consumers must weigh these factors according to their priorities.
Which should you buy?
Choosing between the PowerSmart Self Propelled Gas Lawn Mower and the WEN 20V Max Cordless Brushless Lawn Mower ultimately depends on individual needs and preferences. If you value power and versatility with the ability to handle various terrains, the PowerSmart mower is a strong contender. However, if you prioritize ease of use, lower maintenance, and affordability, the WEN mower is an excellent choice. Each mower serves its purpose well, making the decision hinge on whether you prefer a gas-powered or battery-operated solution for your lawn care needs.
