Description
Overview:
The V-Belt 6340 704 2101 is a drive belt for Viking/Stihl pedestrian lawn mowers, used to transmit power reliably between the engine and the drive system. Built from durable, oil- and abrasion-resistant rubber with cord reinforcement, it is designed to resist stretching and slipping under normal mowing loads. This belt keeps cutting and/or self-propel functions operating smoothly on machines such as the Viking MB 545 and MB 545.0 V. It is a direct replacement by Stihl for worn or snapped belts, helping restore consistent performance and extend mower service life. Suitable for domestic and professional users, it fits a range of MB 545 and RM 545 variants. Always compare the routing and length with the original belt and follow the mower's service manual during fitting.
Key Features:
- Stihl MPN 6340 704 2101 for clear identification and correct replacement
- Robust rubber construction with internal cord reinforcement to reduce stretch and maintain tension
- Reliable power transfer for blade drive and/or self-propel systems, depending on model
- Smooth, quiet running to minimise vibration and belt slip under load
- Compatible with a wide family of Viking/Stihl MB 545 and RM 545 models for straightforward sourcing
- Designed for an accurate fit on the correct pulleys and guides, supporting long service life
- Suitable for routine maintenance schedules to prevent downtime in the mowing season
- Fits using standard hand tools; check belt routing and tension as per the mower manual
Typical Applications:
Replacing a worn, cracked, glazed, or broken mower drive belt to restore cutting performance and self-drive function on Viking MB 545-series and Stihl RM 545-series walk-behind mowers.
