Last Updated: July 2024

Overview

This Model MT665E by Challenger offers a 290 hp AGCO POWER engine, featuring turbocharged with an air-to-air intercooler and a liquid cooling system. The 6-cylinder engine provides a displacement of 512.6 ci, and operates at a rated RPM of 2100. The continuously variable transmission (CVT), also known as a Techstar CVT, allows for infinite forward and reverse gears. The tractor uses hydrostatic power steering and features a closed center load sensing (CCLS) hydraulic system. The rear type hitch falls under category III/IVN. The chassis and drive type are not specified. The tractor's length is 218.6 inches, its height (with the cab) is 141 inches, and its operating weight is 23810 lbs.
