Product Description

The RM 4 RTP petrol-driven mulching lawn mower has been specially designed for demanding, frequent and extended use in professional applications. Thanks to the combination of a powerful OHV engine and specially shaped mulching blade, the STIHL RM 4 RTP is the ideal mulching lawn mower for large lawns up to 2,500 m2 in size. Freshly cut grass is shredded into fine particles, and delivered directly back onto the turf to become a nutrient-rich fertiliser, supporting lawn health with valuable minerals.

Reinforced axle brackets and axle bolts ensure durability. Professionals also very much appreciate the gearbox and crankshaft protection which makes this power tool even more robust. For additional comfort the STIHL RM 4 RTP petrol-driven mulching mower features an easy-start function to minimise the effort needed during starting, as well as double ball-bearing wheels. The super-soft handle also means better working ergonomics. Another comfort benefit: wheel drive and aluminium rims with rubber tyres help you mulch large lawns efficiently and without fatigue. The 53 cm cutting width also helps you make rapid progress in your work. You can select the right lawn height by means of central cut-height adjustment, in 5 levels from 30 mm to 70 mm. Its handlebar can be folded using Quick-Fix quick-release clamps, for easy transport and compact storage. The STIHL anti-vibration system ensures smooth running and welcome relief for your muscles and joints when mowing for longer periods.
