Overview

The Challenger MT665C is a 4WD row-crop farm tractor produced between 2009 and 2010 in Beauvais, France, featuring an AGCO SISU POWER 8.4L 6-cylinder diesel engine. It utilizes a Techstar continuously variable transmission with infinite forward and reverse gears and is equipped with a closed center load sensing hydraulic system. The tractor has a standard operating weight of 25,795 pounds and was available with either selective catalytic reduction or internal exhaust-gas recirculation emission control systems.

Ideal Applications

Tested Power and Drawbar Performance: Nebraska Tractor Test data for the MT665C recorded a maximum PTO output of 290.3 hp and a maximum drawbar pull of 34,130 lbs using its SCR technology engine.

Rear Hitch and Lift Specifications: The tractor is equipped with a Category III rear hitch featuring electronic lower-link draft sensing and a maximum lift capacity of 26,460 lbs at the ends.

Engine and Charging Configuration: The 512.6 ci liquid-cooled engine operates with a 240-amp charging system provided by dual 120A alternators and a high-pressure common rail fuel system.
