The transmission system includes six forward gears enabling maximum speeds of 27.8 mph forward and 33.9 mph reverse, offering adequate mobility between work areas. The fuel tank capacity of 75.3 gallons supports extended operational periods without frequent refueling. Tire specification of 13.00-24-10PR ensures traction and durability on construction surfaces. The isomount cab design provides operator comfort and vibration isolation during extended grading operations. This configuration makes the GD611A-1 suitable for municipal road maintenance, highway construction, and site preparation work requiring reliable, productive grading performance.
