Q. What are the 3 types of combines harvester?

Currently three distinct varieties of combine harvesters are in widespread use:Self-propelled: These harvester machines on wheels work great on fields with compacted soil. They represent the industry standard and are widely distributed throughout the country.Track: These move along on tracks rather than wheels. They perform admirably in places where wheels would likely get stuck. Rice and other crops grown in wetland conditions are often harvested with track combines.Tractor Mounted: Tractors are attached to the top of these harvesters and used to move them. They are most effective on large farms with loose soil.
