Challenger MT535E

Last Updated: July 2024

Overview

The Challenger MT535E is powered by a turbocharged intercooled 6-cylinder diesel engine from AGCO Power with a displacement of 402 cubic inches and a compression ratio of 17.4 to 1. It delivers a maximum power output of 141.1 hp at 2100 rpm. The engine uses liquid cooling and meets Tier IV emissions standards with selective catalytic reduction. The transmission offers continuously variable and six-speed power shift modes with two mechanical ranges for forward (0-17 mph and 0-25 mph) and reverse (0-10 mph and 0-23 mph) speeds. Key hydraulic specs include a maximum force of 16,750 lbs through the hitch, sustained pressure of 2,901 psi, and pump delivery rates up to 41.9 GPM. Standard PTO speeds are 540 rpm at 1,868 engine rpm or 1,000 rpm at 1,903 engine rpm. Dimensions include a wheelbase of 113.2 inches and static weight with operator of 17,360 lbs (rear: 10,220 lbs, front: 7,140 lbs). Detailed drawbar performance and sound level data is also available.
