It is also designed for ease of use, with a push-button start and automatic oiling to ensure proper chain lubrication, making it an excellent choice for tree felling, limbing, and pruning tasks.
Overview of the Husqvarna 120 Mark III Gas Chainsaw
The Husqvarna 120 Mark III Gas Chainsaw is a solid choice for homeowners seeking a lightweight and efficient cutting tool. At $219.99, it is priced about 11% lower than the Greenworks model, making it a more budget-friendly option. With a 38-cc X-Torq engine, it offers powerful performance and efficient fuel consumption. The chainsaw is equipped with essential safety features like an inertia-activated chain brake and LowVib technology to reduce vibrations, ensuring comfort and safety during operation.
Performance Comparison
In terms of performance, the Greenworks 80V chainsaw boasts up to 150 cuts on 4x4 lumber on a single charge, rivaling the capability of a 42cc gas chainsaw. This impressive output highlights its efficiency for heavy-duty tasks. On the other hand, the Husqvarna 120 Mark III, with its X-Torq engine, provides efficient combustion that enhances power and torque. While both chainsaws are designed for cutting wood, the Greenworks model’s electric motor offers quieter operation compared to the gas-powered Husqvarna, which can be significantly louder during use.
Ease of Use
The Greenworks 80V chainsaw is designed for user-friendliness, featuring a push-button start that eliminates the hassle of gas and fumes. With its lightweight design, it also allows for easy maneuverability. Conversely, the Husqvarna 120 Mark III includes a separate choke and stop switch, which prevents accidental flooding and enhances safety while operating. Although both models incorporate automatic oilers for chain maintenance, the Greenworks chainsaw's electric nature simplifies maintenance further by eliminating components such as carburetors and spark plugs.
Safety Features
Safety is critical when operating chainsaws, and both models incorporate notable safety features. The Husqvarna 120 Mark III includes an inertia-activated chain brake, which helps prevent accidents during operation. Additionally, its LowVib technology minimizes vibrations, promoting a more comfortable cutting experience. Meanwhile, the Greenworks chainsaw emphasizes safety through its electric operation, reducing the risks associated with gas chainsaws. However, it lacks some of the mechanical safety features found in gas-powered models, making it essential for users to remain vigilant.
Maintenance and Longevity
The Greenworks 80V chainsaw benefits from less complex maintenance routines due to its electric motor, which requires no gas, oil changes, or spark plug replacements. This translates to potentially lower long-term maintenance costs. The brushless motor is also designed for extended lifespan, providing reliable performance over time. In contrast, the Husqvarna 120 Mark III requires regular maintenance typical of gas chainsaws, including air filter cleaning and fuel management. However, its Air Injection technology helps enhance engine life by preventing debris from clogging the filter.
Battery vs. Gas
The Greenworks 80V chainsaw operates on a lithium-ion battery system, which allows for quiet operation and immediate starting capability. This makes it highly suitable for residential areas where noise restrictions may apply. Alternatively, the Husqvarna 120 Mark III, being gas-powered, offers the advantage of extended run time, as users can simply refill the tank to continue working. While the battery of the Greenworks provides convenience, the Husqvarna’s gas engine can be a better choice for users needing longer operational periods without interruption.
Which should you buy?
Ultimately, choosing between the Greenworks 80V 18" Brushless Cordless Chainsaw and the Husqvarna 120 Mark III Gas Chainsaw depends on your specific needs and preferences. If you prioritize ease of use, quiet operation, and lower maintenance, the Greenworks model is an excellent option despite its higher price. However, if you are looking for a more budget-friendly choice with powerful performance and longer run time, the Husqvarna 120 Mark III stands out as a reliable alternative. Each chainsaw has its unique advantages, making both worthy contenders in the market.
