View Full Test Data →

Overview

The Challenger MT685E is a high-performance row-crop tractor featuring a 370 hp AGCO POWER 8.4L 6-cylinder diesel engine and a Techstar continuously variable transmission for infinite speed control. Built in Jackson, Minnesota, this 4WD machine is designed for heavy-duty operations with a massive 26,455 lb rear lift capacity and advanced AgCommand ready technology.

Ideal Applications

High-Capacity Implement Operation: With a rear lift capacity of 26,455 lbs and a closed center load sensing hydraulic system delivering 54 gpm flow at 2,900 psi, this tractor is built to manage large, demanding implements and heavy attachments.

Heavy Tillage and Draft Work: Utilizing a tested maximum pull of 21,875 lbs and 269.8 hp at the drawbar, the MT685E provides the raw power and traction required for intensive soil preparation and heavy towing tasks.

Precision Row-Crop Management: The combination of a Techstar CVT for precise speed adjustments and the standard integration of AUTO-GUIDE 3000 and AgCommand systems makes this tractor highly suitable for accurate row-crop field work.
