AS 531,4T MK Operating Manual

The Professional profile: stable and weight-optimized steel structure, reduced hand-arm vibration by the VibrationProtect damping system, high-performance engines - either as AS 2-stroke engine or B+S four-stroke engine.

The blade clutch stops the blade and the engine keeps on running. You can cross paths without any problems without affecting your environment by dangerous stone impact and without raising unpleasant dust.

When emptying the grass collecting bag, just disengage the blade and empty the bag without cutting the engine. This provides maximum safety and in addition engine re-start after blade stop has become obsolete too.

A unique operating concept: one hand controls the drive and blade clutch, whilst the other controls the speed which can be locked via Varioshift to allow for comfortable, steady propulsion.
