View Full Test Data →

Overview

The Challenger MT525D is a row-crop farm tractor produced between 2013 and 2014 in Beauvais, France, featuring an AGCO Power 6.6L six-cylinder turbocharged diesel engine. It is equipped with either a 16-speed or 24-speed power shift transmission or a TechStar CVT, delivering a tested maximum PTO output of 141.9 hp. The machine utilizes a closed-center load sensing hydraulic system with a 29 gpm flow rate and a Category III/II rear hitch.

Ideal Applications

Engine and Emission Configuration: The 6.6L liquid-cooled engine utilizes electronic high pressure common rail fuel injection and selective catalytic reduction to meet Interim Tier IV emissions standards while producing a tested 141.9 hp at the PTO.

Transmission and Axle Options: Operators can utilize three transmission types including AutoPower IV, AutoPower VI, or TechStar CVT, which can be paired with flange rear axles or adjustable bar axles up to 113 inches in length.

Tested Drawbar and Hydraulic Output: Performance testing recorded a maximum drawbar pull of 15,240 lbs and a maximum drawbar power of 118.2 hp, supported by a hydraulic system operating at 2900 psi with up to four valves.
