TRANSMISSION
The Challenger MT655E features a Techstar continuously variable transmission (CVT), offering infinite forward and reverse gear options across two ranges, enhancing operational flexibility and efficiency. This transmission system allows for seamless speed variation, minimizing power loss and maximizing torque delivery, which is advantageous for tasks requiring precise speed control, such as tilling or planting. However, while CVTs typically provide smooth operation, they can be more complex to maintain compared to traditional gear transmissions, potentially leading to higher long-term service costs.
