Tier D — Global / grey-import Two-wheel tractor
Yanmar YK850MK
Yanmar's YK850MK is a professional multi-purpose power tiller (kanriki) for vegetable growers — note it runs an air-cooled Yanmar GB290 8.5 PS petrol engine, not diesel: a 4-forward / 4-reverse transmission with single-lever high/low sub-transmission, all controls grouped at the handle, ~100 kg. A Japanese-market machine bought by grey import in the UK/EU. Engine (petrol), 8.5 PS power and ~100 kg weight verified via Yanmar; working width is attachment-dependent so still flagged. Engine, 296 cc, 8.5 PS, 100 kg (recoil-start K spec) and the 4+4 gearbox verified against the Yanmar Japan specification page, September 2026.
