FOUR-POT POWERHOUSE

摘要

For years Valtra has pushed the boundaries of power and torque with four-cylinder engines from its Scandinavian sister company Sisu. Back in 2003 the Finnish firm launched what it proclaimed to be the world's most powerful four-cylinder tractor - the147hp M150. And now, driven inevitably by meaner, greener emissions rules, the company's 90-150hp line-up has seen a revamp, with the N163 flagship staking its claim as the pokiest four-pot on the market.
