Tractor Info


The 1066 was capable of 100-plus drawbar horsepower. Along with plowing and other heavy tillage operations, the 1066 was also capable of most cultivating jobs. An adjustment range of 60 to 84 inches was possible in the front axle, and the rear wheels could be adjusted from 60 to 104 inches. Despite its horsepower, the compact 1066 only used a 105-inch wheelbase with an adjustable front axle. The 1066 was available with gear or hydrostatic drive.
