Stihl RM 4 RTP 21″ Alloy deck, Variable, Mulching Mower


Robust and powerful professional petrol mulching mower


The STIHL RM 4 RTP petrol lawn mower has been developed for professional use. With a cutting width of 53 cm, this mulching mower provides high-quality results on large lawns and impresses with its powerful engine. The self-propulsion facilitates the mowing of large lawns and is a significant aid to working, particularly on inclines. The foldable handlebar enables space-saving transport. In addition to practical details such as the super-soft grip for ergonomic handling and the central five-setting cutting height adjustment, it also meets the exacting mowing standards and requirements of garden-care professionals. For greater durability, the axle brackets and axle bolts are additionally reinforced. The robust aluminium rims with rubber tyres, double, sealed ball bearings and the gearbox and crankshaft protection extend the service life of this sturdy professional machine. The specially shaped mulching blade shreds the grass into fine particles, which then fall back onto the turf. In this way, the lawn is supplied with nutrients and moisture. Thanks to its low vibration values, lengthy periods of work can be performed without problem with this petrol lawnmower
