The Stihl 064 and 066 are powerful, professional-grade chain saws renowned for their durability, performance, and versatility. These saws are favored by arborists, loggers, and forestry professionals due to their ability to handle demanding tasks with ease. The 064 and 066 share many core design features, including their robust, cast magnesium crankcases, reliable Stihl-M-Tronic electronic ignition, and a robust, efficient piston design. Both models utilize a 71.6cc engine, producing comparable power output and torque, making them suitable for felling large trees, heavy-duty limbing, and demanding timber processing. However, they differ in minor details, such as the 066's longer bar length capacity, which allows for tackling even larger logs. Both the Stihl 064 and 066 are equipped with sophisticated safety features, including a chain brake system that instantly stops the chain in case of kickback, a decompression valve for easier starting, and an anti-vibration system to minimize operator fatigue. These saws also benefit from a robust construction, with a reinforced crankshaft and a durable air filter system. The 064 and 066 feature a manual oil pump, allowing for precise control of chain lubrication, and a large fuel tank, ensuring extended run times between refills. Their modular design allows for easy access to components for maintenance and repair, contributing to their long-lasting lifespan. These features make the Stihl 064 and 066 true workhorses, capable of handling the most challenging forestry tasks with power, precision, and reliability.
