Challenger MT575E

Last Updated: July 2024

Overview

The Challenger MT575E is fitted with a 6-cylinder diesel engine provided by AGCO Power, offering a displacement of 449 ci. The liquid-cooled engine is turbocharged and intercooled, contributing to a rated power output of 240 hp at 2100 RPM. An electric starter is part of the engine's configuration. The tractor's substantial power is managed via a continuously variable transmission (CVT) with infinite speed adjustment in both forward (Low range 0-11 mph, high range 0-25 mph) and reverse (Low range 0-19 mph, high range 0-19 mph) directions, giving this tractor a wide range of speed and torque options. The tractor operates on a closed-center load sensing hydraulic system and includes a rear hitch of type III/IIIN. Additional details from independent test results have been incorporated, including maximum torque, torque rise, hydraulic performance, fuel efficiency, and fuel consumption figures.
