ECHO CS-7310SX Professional Chainsaw – 20" Bar (X-Series)
Command the absolute apex of ECHO’s heavy-duty cutting power with the ECHO CS-7310SX 20-Inch Chainsaw. Designed from the ground up for full-time professional forestry and commercial logging, this elite X-Series machine brings true, unadulterated power to the most challenging environments. At its core is a colossal 73.5cc 2-stroke engine that generates a devastating 4.1 kW of output. This immense powerplant produces massive torque, allowing professional fallers to effortlessly slice through the thickest, hardest timber without the chain speed ever dropping.
The CS-7310SX is built to survive the brutal realities of daily commercial logging. Featuring ultra-tough magnesium crankcase plates, the chassis is highly resilient to crushing impacts yet remains astonishingly light at just 6.7 kg (dry). To ensure the engine breathes easily in severely dusty conditions, it utilizes a newly developed centrifugal separation G-Force system. This highly advanced pre-cleaner violently spins dust and debris out of the intake path before it can even reach the large pleated air filter, virtually eliminating mid-shift maintenance. This 70cc class commercial chainsaw is the ultimate, dependable weapon for professional timber harvesting.
