Huge John Deere X9 aims to beat the competition

摘要

John Deere has finally lifted the lid on its new flagship lOOt/hour twin-rotor combine after being stubbornly tight-lipped on details when it was launched at Agritechnica last year.There was little doubt that the US firm was getting left behind by Claas, Agco and New Holland's twin-rotor machines, as the previous range-topping JD S-series harvester only had a single-rotor setup and struggled to compete with its rivals' dual separators.All that looks to have changed. The new two-model X9 range starts with the 639hp 1000, which sits below the flagship 1100. This tops out at 700hp and both run from a 13.6-litre six-cylinder John Deere engine.
