Weighing in at just over 10 pounds, the 338XPT allows users to work for extended periods without fatigue, making it an ideal choice for arborists and forestry workers.

At the heart of the Husqvarna 338XPT is its efficient engine, which not only provides robust cutting performance but is also designed with EPA III compliance in mind.

Comfort and usability are also central to the design of the 338XPT. The chainsaw includes an ergonomic handle that allows for better control during operation, reducing vibrations and enhancing user comfort. Additionally, the chainsaw's easy-access chain tensioning system makes adjusting the chain as simple as possible, ensuring that users can quickly get back to their tasks at hand without unnecessary delays.

For safety-conscious users, the Husqvarna 338XPT is equipped with features like a combined choke/stop control that allows for easy starting and reduces the risk of engine flooding. Furthermore, the chainsaw's inherent balance and lightweight structure contribute to safer handling and operation.

In summary, the Husqvarna 338XPT EPA III is a top-of-the-line chainsaw that combines power, efficiency, and user-friendly features, making it a prime choice for professionals in the forestry and arborist fields.
