2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

STIHL ErgoStart cuts the effort required to start the tool by half, while the starter cord can be pulled at just one third of the normal force. A coil spring between the starter cord and the crankshaft smoothes out force peaks, making them virtually undetectable through the cord itself.

When used in conjunction with a harness, the bike handle enables a smooth mowing action. The bike handle allows the machine to be easily guided, making it ideal for working on large areas and thus reducing fatigue.

For use with loop handle machines.
