Introduction
Challenger MT665E Row-Crop Tractor
The Challenger MT665E is a high-horsepower row-crop tractor manufactured by AGCO in Jackson, Minnesota, between 2014 and 2020. This machine is designed for large-scale agricultural operations requiring high levels of power, precision, and operational efficiency.
Engine and Emissions
The tractor is powered by an AGCO POWER 6-cylinder, 24-valve diesel engine with a displacement of 8.4 liters (512.6 cubic inches). It is equipped with a turbocharger and an air-to-air intercooler, producing a rated power of 290 hp (216.3 kW) and a maximum power output of 320 hp (238.6 kW) at 2100 RPM. To comply with Tier IV emission standards, the engine utilizes selective catalytic reduction (SCR) technology.
Transmission and Drive
The MT665E features the Techstar CVT (continuously variable transmission), which allows for infinite forward and reverse speed control across two ranges. This transmission is paired with a four-wheel-drive system, an electro-hydraulic differential lock, and hydrostatic power steering to ensure traction and maneuverability in various field conditions.
Hydraulics and Hitch
The hydraulic system is a closed-center load-sensing (CCLS) type, operating at a pressure of 2900 psi (200 bar) with a pump flow capacity of 54 gpm (204.4 lpm). It supports between four and six valves. The rear hitch is a Category III/IVN type, capable of a maximum lift capacity of 26,455 lbs (11,999 kg) at the ends.
Operator Environment
The tractor is equipped with a standard cab featuring air conditioning. For improved operator comfort, an optional OptiRide Plus hydraulic cab suspension system is available. The machine is also factory-prepared for AgCommand telemetry and the AUTO-GUIDE 3000 guidance system.
Conclusion
The Challenger MT665E represents a robust solution for professional farming, combining high-capacity hydraulics and a flexible CVT transmission. It is specifically suited for heavy-duty row-crop applications where reliability, precise speed control, and modern guidance integration are essential.
