All MT600D Series tractors are equipped with AGCO Power™ engines that guarantee precision power and high performance.

  • These engines feature Tier IVi-compliant Electronic Engine Management (EEM). EEM makes fine adjustments to the fuel injection, resulting in lower emissions, more power and fuel economy. EEM also enables a range of advanced engine control functions, including Engine Speed Control.

  • The revolutionary e3 SCR technology is a post combustion, after-treatment process that takes place in the exhaust system, rather than in the engine. The system is not only better for the environment, but it allows for optimum engine tuning at the factory.

  • Switches are mindfully mounted on the armrest enabling engine speed to be pre-set and memorized.

  • The ability to return quickly and easily to precise engine speeds, will boost productivity, improve work quality and simplify operation for daily tasks.
