pulverizer performance evaluation mathematical model

The field efficiency (FE) ranged between 51.61 and 80.18% in across the soil depths and tractor speeds at 1.1, 1.6 and 2.5 km/h. The TFC values increase with tractor speed, indicating that the time required for the rotary clod pulverizer operation was lesser at higher speed than the time required for the operation at lower speed.
