TRANSMISSION

The Challenger MT225 features a hydrostatic transmission with infinite gears, allowing for seamless speed adjustments, which enhances maneuverability in varied agricultural tasks. The 2-range capability enables efficient operation in both low-speed, high-torque applications like tilling and high-speed transportation. However, the hydrostatic system may lead to higher maintenance costs compared to traditional gear systems, particularly in demanding environments.

Type	hydrostatic
Gears	infinite (2-range) forward and reverse

MECHANICAL

The Challenger MT225 features a 4x4 MFWD system, enhancing traction and stability on various terrains, making it suitable for heavy-duty field work. Its hydrostatic transmission allows for smooth speed adjustments, ideal for precision tasks, while the mechanical rear differential lock enhances power delivery in challenging conditions. However, the dry shoe brakes may require more frequent maintenance compared to wet systems, potentially impacting long-term cost efficiency.
