Compact clear-out mower for mulching in confined spaces

Compact and agile. At 30 kg with a 42 cm cutting width, the AS 420 ProClip 4T mulching mower is perfectly suited for clean-out tasks in confined and angled spaces. The Briggs & Stratton engine not only delivers up to 5.7 hp, its asymmetric arrangement also ensures excellent handling thanks to a balanced distribution of weight.
A third crankshaft bearing and friction discs on the mulching blade protect the engine in the event of unseen obstacles. A galvanised steel mulching unit with reinforced edges guarantees a long service life, robustness and operator safety, even in difficult conditions.
Double ball-bearing front wheels and rear wheel drive provide easy handling. The front wheels’ special wedge shape minimizes impact on the grass, which quickly springs back up to be cut by the blade. This makes the cutting pattern extremely uniform. Cutting height can be adjusted centrally in a range from 40–80 mm via a spring-supported system, by foot or by hand.


Save time and money by mulching.

A deep mulching unit delivers even finer cutting results. The mulching blade cleanly cuts grass up to 18 cm high and simultaneously generates an airflow that whirls the cuttings in the mulching unit. The mulching blade’s multiple cutting edges chop and mulch the grass several times. The cuttings then sink into the turf, forming a layer of mulch that both fertilises and protects the lawn from drying out. The AS 420 ProClip 4T saves 30% more time when compared with collection bag lawn mowers by avoiding the need to empty the collection bag or dispose of the cuttings.
