Operation and Efficiency of Different Types of Combines
The need for bigger and faster harvesters has brought forth models that work with higher efficiency and better robustness. In a broad sense, different types of combines fall into two categories - controlled combine harvesters and self-propelled harvesters. The controlled harvesters are further classified into those with auxiliary engines and those without.
