Traction and Tractor Performance

The torque input (T) develops a gross traction (GT) acting at the contact surface. Part of the gross traction is required to overcome motion resist ance (MR), which is the resistance to the motion of the wheel, including internal and external forces. The remainder is equal to the net traction (NT) that the wheel develops, given by NT = GT - MR.
