Caterpillar Mobil-Track System (MTD)
The best of wheels and tracks! 

  • More traction and stability than a wheel machine, yet able to travel on paved roads.
  • Differential steering — provides continuous power to both track belts, even in a turn.
  • Power shift transmission, with inching foot pedal, 10 forward speeds and two in reverse.
  • Extremely maneuverable—can turn in its own length.
  • Very mobile—capable of speeds up to 18 mph.
  • Economical—rubber belts outlast tires.
