Last Updated: July 2024

Overview

The Challenger MT835C is a powerful agricultural tractor manufactured by AGCO Corporation. It is powered by a Caterpillar C15 ACERT turbocharged aftercooled diesel engine with 6 cylinders and a displacement of 928 cubic inches. The engine produces a maximum power output of 402.32 horsepower at 1800 rpm and has a compression ratio of 16.5:1. The transmission is a selective gear fixed ratio with full range operator controlled power shift, offering 16 forward gears and 4 reverse gears. Key specifications include a width of 141.8 inches, length of 270 inches, height of 138.1 inches, and an operating weight of up to 50,000 pounds with ballast. The hydraulic system features a closed center pressure-flow compensated design with a maximum pump delivery rate of 44.5 GPM and a maximum force exertion of 20,936 pounds.
