Husqvarna 545 RXT AutoTune mower

Husqvarna 545 RXT AutoTune for professional shrub cutting.
Properly equipped with metal guards, it becomes an excellent tool for forestry clearing work.
This brushcutter combines high performance with excellent manoeuvrability.
Both cutting modes benefit from the inclusion of a high-torque bevel gear positioned parallel to the ground for optimum performance.
Mowing with both the knife and the corded mower head, both are equally effective and convenient.
The conical power gear with parallel inclination to the ground makes this possible.
The 545RXT is equipped with a simplified starting system.
The AutoTune system allows hot or cold starting without the risk of carburettor choking.
The solenoid valve system continuously adjusts the fuel mixture.
Easier starting
