Bosch V-belt - F016A57941

Genuine Bosch drive (V) belt F016A57941 — the wrapped V-belt used to drive the cylinder/blade assembly on older cylinder lawnmowers (the belt itself is commonly stamped A57941). Designed as the cylinder/cutter drive belt, it’s a wrapped V construction with high‑strength cords and oil/heat resistance suitable for mower drive loads.

Examples of machines this part is listed to fit include Qualcast Classic Electric 30/30S and Classic Petrol 35S and 43S; Atco Balmoral and Windsor series (various 14/17/20 models); Allett Classic and Kensington ranges (12E, 14L, 17L, 20K, Liberty 43); plus Suffolk Punch and some Rover cylinder models. (Check your model number against the list to confirm fit.)

Notes for the repair: the belt typically replaces part numbers shown as A57941/F016A57941 and is the belt that directly drives the cylinder blades — you’ll usually see that marking on the belt edge. Some replacement/specification listings describe the belt as a wrapped V‑belt with high‑tensile (aramid-style) cords and good resistance to oil and heat for reliable service in mower drives.
