The Krone Big X 480/530/580/630 series models have undergone a major facelift, with new technology and features. All models are powered by MTU engines (up to 653hp) and comply with Stage 5 emission standards. Mounted sideways, the engine sits right at the back which Krone says is for optimum weight distribution. When shod on 710/70R42 tyres, these foragers have a 3m transport width.
