Challenger MT655E

Last Updated: July 2024

Overview

The MT655E from Challenger, part of the AGCO family, is a robust and efficient tractor designed with powerful performance capabilities. It features a liquid-cooled, turbocharged 6-cylinder diesel engine with air-to-air intercooling, providing a robust 265 horsepower while operating at 2100 RPM. The engine relies on a selective catalytic reduction (SCR) system for emission control, complying with stringent Tier IV emission standards. This tractor boasts an advanced Techstar Continuously Variable Transmission (CVT) system, providing infinite forward and reverse gears within 2 ranges. The hydrostatic power steering presents unparalleled maneuverability, complementing the closed center load sensing (CCLS) hydraulic system. The tractor's cab height is 141 inches, ensuring ample visibility for operators, while the total tractor length is 218.6 inches. The operational weight stands impressively at 23810 lbs. While some specification data for this model remains incomplete, this durable workhorse's primary features highlight its advanced capabilities.
