Description
Overview:
The Mulching Attachment for Stihl petrol lawn mowers is a genuine Stihl insert that converts your mower to mulch mode by blocking the discharge path so cuttings are finely recirculated and returned to the turf. Built from durable, impact‐resistant polymer, it is engineered for a precise fit and reliable service life. By turning clippings into nutrient‐rich mulch, it helps maintain lawn health and reduces green waste handling. This attachment is designed for selected Stihl walk‐behind models, including the MB 655.3 V and MB 655.3 VS, and is identified by Manufacturer Part Number 6374 766 8300. It is a practical upgrade for users who want a cleaner finish without collecting, especially on regularly cut lawns.
Key Features:
- Genuine Stihl part for assured compatibility and performance (MPN 6374 766 8300)
- Tough polymer construction for long‐lasting use in demanding mowing conditions
- Optimised fit for the Stihl MB/RM 655 series for consistent mulching results
- Finely recycles clippings to return nutrients to the soil and support grass health
- Reduces or removes the need to bag and dispose of cuttings
- Quick to fit and remove for switching between collection and mulching modes
- Low maintenance design with smooth surfaces that are easy to clean
- Helps achieve a neat, even finish when mowing at correct height and frequency

- Genuine status helps protect mower warranty and preserves expected cutting performance
Typical Applications:
Used for regular lawn maintenance where a clean, even finish is required without collecting clippings. Ideal for residential gardens, housing estates, schools, sports turf edges, and commercial grounds. Best suited to lawns cut frequently and in dry conditions, where mulched clippings break down quickly to feed the soil and improve lawn appearance.
