All You Need To Know About A Combine Machine

A combine machine is a modern and versatile machine designed to harvest a range of crops efficiently. It threshes and cuts grains and crops. Cleaning and harvesting cereals like rye, wheat, sorghum, barley, oats, and crops, numerous non-grain crops too like rapeseed, sunflower, flax, and soybeans seeds are done using this machine.

How does it work?

A combine is a cutting device that cuts the grain or seed crops and then delivers them to the threshing machine. A header is a cutting-gathering component that takes the grain with a straw. The grains are rubbed against a concave exterior using a threshing cylinder.

The straw takes some chaff and grain to the straw deck. Here grain is shaken and delivered in the cleaning shoe. While some of the chaff and grain get directly transferred to the cleaning shoe. An air blast cleans and separates the grain. The grain is then dropped into a clean air auger after going through the blast of air. The air auger transfers it to the elevator and then into a storage tank.

Types of combine


There are basically three types of combine machine:

  1. Self-propelled: If hard soil is present on your farm, then self-propelled machines will be best.
  2. Track: Tracks are present in these machines in place of wheels. They work well in areas where the land is wet and spongy. Rice and some wetland crops are harvested using track combines.
  3. Tractor Mounted: These harvesters have tractors fixed on top of them. They perform their best when the soil is loose on land, and the farmed area is also extensive.

Hill side leveling

The combine machine is retrofitted with a hillside leveling system in the Pa louse region, pacific northwest, United States. This helps in harvesting the fertile but steep soil in the area. Hillsides are steep, with about 50% slope.

The primary advantage of hillside leveling is more efficiency near hillsides. The chaff and grain slide onto one side of the separator without leveling and come outside the machine in large balls instead of getting separated.

Side-hill leveling

Side hill machines function similarly to hillside machines. The combine is leveled to the ground, so the threshing gets conducted efficiently. These machines are used in the Palouse region sparsely. A level land combine and a sidehill combine are of the same height. On the other hand, hillside leveling is 2-5 feet higher to provide a smooth ride.

Combine fires

Like any other thing, combines have their own disadvantage: fire. The main cause behind the fire is an accumulation of dry crops and dust near the engine.
