Last Updated: July 2024

Overview

The Challenger MT965C is a powerful tractor manufactured by Challenger, offering a maximum power output of 501.68 HP (374.10 kW) at 1750 rpm from a Caterpillar C18 ACERT turbocharged, liquid-cooled diesel engine with 6 cylinders and a 24-valve configuration. The engine has a displacement of 1105 cubic inches, a bore of 5.709 inches, and a stroke of 7.205 inches. The tractor deploys a Caterpillar Powershift transmission with 16 forward gears and 4 reverse gears. It is equipped with six 520/85R46 tires on the front and rear, with detailed tire pressures provided in the test results. The operating weight is 60000 lbs when ballasted and 50890 lbs when unballasted. Detailed performance metrics, including fuel consumption rates, drawbar performance, and hydraulic system capabilities, are available from the independent test results.
