Product Description

The robust RM 4 RT petrol-driven mulching lawn mower from STIHL provides efficient support for discerning garden owners and their garden maintenance. A cutting width of 53 cm and convenient wheel drive enable you to mulch large lawns of up to 2,500 m2. The freshly cut grass is shredded into fine particles and distributed directly back onto the turf to act as a nutrient-rich fertiliser, supporting the growth of your lawn with valuable minerals.

The combination of a powerful OHV engine and the specially shaped mulching blade in the mower unit makes the STIHL RM 4 RT an effective mulching lawn mower. For further comfort, the STIHL RM 4 RT mulching mower features an easy-start function for minimum effort during the starting process and double ball-bearing wheels. The super-soft handle also improves ergonomics as you 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.
