431SX
The lightest and most powerful chain saw in its class.
The Shindaiwa 431sx has been designed to be ultra light weight without compromising on power. The saw weighs just 4.3 kg yet has a 42.9 cm³ professional grade engine that provides an impressive 2.3 kW or 70 ps/L of power. These specifications give it the best power to weight ratio in its class and mean you get great power coupled with extreme maneuverability. Suitable for smaller jobs like cutting firewood all the way up to the felling of small trees, the 431sx offers versatility for the professional. The industry leading air filtration system utilizes centrifugal forces to remove dust and debris before reaching the automotive style, heavy duty air filter. This is a scaled down version of the system found in the Shindaiwa 731sx.

FAQ
The right bar length depends on the diameter of the wood you cut and your experience. Shorter bars are lighter and easier to handle for pruning and light work, while longer bars suit felling larger trees. Our Tool finder can help you compare models.
