As the 543RS uses a 40.1 cc engine for superb power, while also benefiting from Husqvarna’s X-Torq technology. This increases torque over a wider rpm range for maximum cutting power, while enabling improved fuel efficiency.
The air filter is also efficient, providing less cost for service and reducing engine wear. A fuel pump designed for easy starting is also part of this machine’s repertoire, making it easier and more reliable to get up and running.
Designed for heavy duty, intensive use, the 543RS is a durable and robust machine. For example, it features a heavy duty clutch to allow for tough work with long cords and a large diameter cutting knife, while the handle is similarly robust, attached to the tube with a die cast clamp.
