Retrofitted equipment

  • Mulching function Zoom
    Mulching function

    With the mulch insert, the STIHL ride-on mowers can be converted into mulching mowers. For this purpose, the grass catcher box is simply removed and the mulch insert pushed into the grass catcher tunnel. This allows the grass to be shredded into fine particles inside the closed housing before they fall back into the turf, returning vital nutrients and moisture to the soil. Through this natural form of fertilising, disposal of the clippings is dispensed with.
