Genuine Allett clutch / coupling plate (part no. L12661 — cross‑ref F016L12661) designed to replace the worn friction plate in the drive clutch of petrol cylinder mowers. It restores positive engagement between the engine and the transmission so the cutter cylinder drives smoothly and without slip, and it’s made to the same fitment profile as the original Allett unit for straightforward installation. This part is commonly used on Allett/Buckingham/Westminster cylinder mowers and is also a direct fit for many Atco Club, Royale and Heavy Duty models (examples: Club 20 / Club B20DL, Royale 20/24/30 series, Heavy Duty 20/24/30 and Buckingham 20H/24H/30H). Allett spare parts like this clutch plate are ideal when you need a single, reliable replacement to bring a mower back to correct operation.
