CHALLENGER MT845 TRANSMISSION
The Challenger MT845’s 16-speed full power shift transmission allows for seamless gear changes under load, enhancing operational efficiency and minimizing power loss during gear transitions. This feature is particularly advantageous for heavy-duty applications like tillage or planting on varying terrain, as it provides optimal torque management and speed control. However, operators must be skilled in managing the range of speeds to fully capitalize on the transmission's capabilities and prevent gear overloading in challenging conditions.
