Overview of the Chainsaws
When it comes to choosing a gas chainsaw, both the Husqvarna 120 Mark III and the WTHW 58 cc Gas Powered Chainsaw stand out in their respective categories. The Husqvarna is priced at $219.99, while the WTHW costs $149.99, making the WTHW about 32% cheaper. Each chainsaw offers unique features catering to different user needs, so let's explore how they compare.
Engine Performance and Power
The Husqvarna 120 Mark III is equipped with a 38-cc, 2-cycle X-Torq engine that delivers efficient power and torque. The design focuses on fuel efficiency and reduced emissions, making it a responsible choice for environmentally conscious users. On the other hand, the WTHW features a more powerful 58-cc engine that allows for faster cutting and longer runtime due to its larger fuel tank. This chainsaw is designed to handle more demanding tasks, enabling users to cut quicker and minimize refueling interruptions.
Cutting Bar Length and Versatility
The Husqvarna 120 Mark III comes with a 14-inch cutting bar, which is ideal for homeowners looking for a lightweight tool for general wood cutting and tree pruning. In contrast, the WTHW offers a Quick-Switch system that allows users to swap between a 20-inch felling bar and an 18-inch limbing bar. This versatility makes the WTHW more adaptable for various tasks, from clearing large trees to precision pruning, without needing multiple saws.
Ease of Use and Starting Mechanism
Starting a chainsaw can often be a frustrating experience, but the Husqvarna 120 Mark III features a separate choke/stop switch that prevents accidental flooding, making it easier to get started. Meanwhile, the WTHW boasts a Quick-Start recoil system that fires up reliably on the first few pulls, even in colder conditions. This emphasis on ease of use gives the WTHW an edge for users who want to minimize downtime and frustration.
Safety Features
Safety is paramount when operating power tools, and both chainsaws incorporate features to enhance user safety. The Husqvarna 120 Mark III includes an inertia-activated chain brake that provides an additional layer of safety during operation. In comparison, the WTHW is equipped with a fast-acting inertial chain brake and a low-kickback chain, which collectively improve control and reduce the risk of accidents. Both chainsaws aim to keep users safe, but the WTHW's dual-spring anti-vibration system also helps mitigate fatigue during extended use.
Vibration and Comfort
Vibration can be a significant concern during prolonged chainsaw use, and both models address this issue. The Husqvarna 120 Mark III uses LowVib technology to significantly reduce vibrations between the engine and chassis, allowing for a more comfortable cutting experience. Conversely, the WTHW employs a dual-spring anti-vibration system that also absorbs vibrations effectively. While both chainsaws aim for comfort, the Husqvarna's reputation for reduced vibration might appeal more to users who prioritize comfort during lengthy tasks.
Maintenance and Longevity
Both chainsaws are designed with maintenance in mind, but they take different approaches. The Husqvarna 120 Mark III features Air Injection technology that expels larger dust and debris particles before they reach the air filter, ultimately improving engine life. The WTHW, on the other hand, includes a pro-grade centrifugal air filter and an automatic oiler, which also safeguard the engine from dust and debris. Depending on user preference, each chainsaw offers a unique take on maintaining longevity and performance.
Price Comparison
The price difference between the two models is significant, with the WTHW priced at $149.99 and the Husqvarna at $219.99. This makes the WTHW about 32% cheaper. For budget-conscious consumers or those who may not require the advanced features of the Husqvarna, the WTHW offers a compelling choice without sacrificing too much in terms of performance. However, the investment in the Husqvarna may be justified for users seeking superior technology and features.
Which should you buy?
Choosing between the Husqvarna 120 Mark III and the WTHW 58 cc Gas Powered Chainsaw ultimately depends on your specific needs and budget. If you require a lightweight saw for basic cutting tasks and value features like reduced vibrations and environmental considerations, the Husqvarna may be worth the extra investment. However, if you're looking for a powerful, versatile chainsaw at a lower price point that can handle a variety of jobs, the WTHW is an excellent choice. Both chainsaws offer solid performance, but your final decision will hinge on what features matter most to you.
