Challenger MT585D

Last Updated: July 2024

Overview

The Challenger MT585D is a robust and powerful agricultural tractor produced by Challenger, a part of AGCO. It is powered by an AGCO Power engine with a displacement of 449 cubic inches, supporting a maximum power output of 212 hp and featuring robust turbocharging and intercooling systems. The engine is liquid-cooled to maintain efficient temperatures. Two transmission options are available, including a six-speed power shift (AutoPower VI) and a continuously variable transmission (TechStar CVT), both with 24 forward and reverse gears. The tractor's steering system is hydrostatic power, and it operates with a Closed Center Load Sensing hydraulic system. The rear type III hitch allows for a wide range of towing capabilities with a maximum force exerted of 13,670 lbs. This model offers a closed cab operator station and has an unladen operating weight of 19,145 lbs. Additional key specifications include a maximum torque of 704.4 lb-ft at 1500 rpm with a 51.1% torque rise, hydraulic pump delivery rates up to 28.7 GPM, and a hydraulic delivery pressure of 1915 psi.
