View Full Test Data →

Overview

The Challenger MT545 is a row-crop tractor manufactured in Beauvais, France, between 2002 and 2003. It features a Caterpillar 6.0L 6-cylinder turbocharged diesel engine and is available in 2WD and 4WD configurations with shipping weights ranging from 10,082 to 11,437 pounds. The tractor is equipped with the AutoPower IV 32-speed partial power shift transmission and a Type II rear hitch.

Ideal Applications

Transmission Configuration: The AutoPower IV transmission system utilizes four synchronized gears in two ranges combined with a four-speed power shift on a left-hand power shuttle lever to provide 32 forward and reverse gears.

Hydraulic and Lift Capacity: The rear Type II hitch is rated for a lift capacity of 9,000 pounds at 24 inches, supported by a closed-center pressure flow compensated hydraulic system delivering a total flow of 28 gpm.

Tested Performance Metrics: In Nebraska Tractor Test evaluations, this model recorded a maximum tested PTO output of 156.2 hp and a maximum drawbar pull of 16,635 pounds.
