Agriculture parts

Agriculture machines and combine harvesters consist of many different parts that work together to efficiently harvest crops.

We offer over 700 combine parts for John Deere, Case IH, New Holland, Claas, Massey Ferguson harvesters and AG eqiupment.

  1. Some of the key parts of these machines include:

    1. Cutter bar: A long, horizontal bar with sharp blades that cuts through the crops and separates them from the stalks.

    2. Threshing cylinder: A rotating cylinder with teeth or bars that separates the grain from the stalks and other plant material.

    3. Concave: A curved plate that sits above the threshing cylinder and helps to separate the grain from the stalks.

    4. Straw walkers: A series of slatted steps that move back and forth and help to separate the straw and chaff from the grain.

    5. Grain tank: A large container that collects the harvested grain.

    6. Auger: A screw-like mechanism that moves the grain from the threshing cylinder to the grain tank.

    7. Reel: A series of rotating rods or bars that gently lift the crops and guide them towards the cutter bar.

    8. Chopper: A mechanism that cuts the straw and chaff into small pieces and spreads it out over the field.

    9. Cleaning shoe: A series of sieves and fans that separate the grain from the remaining straw, chaff, and other debris.

    10. Axle and wheels: A set of sturdy wheels and an axle that provide stability and allow the machine to move across the field.

    11. Engine: A powerful motor that provides the energy needed to operate the various mechanisms of the machine.

    12. Cab: An enclosed space where the operator sits and controls the machine. The cab often includes a control panel, steering wheel, and other features to help the operator navigate the field and adjust the machine settings.

    These are just some of the many parts that make up an agriculture machine or combine harvester. Different models and types of machines may have additional features or variations on these basic parts, depending on the specific needs of the farmer and the crops being harvested.

Combine harvester mechanisms and parts

The basic operation of the combine harvester has remained unchanged almost since it was invented.

First, the header cuts the crop and feeds it into the threshing cylinder. This consists of a series of horizontal rasp bars fixed across the path of the crop and in the shape of a quarter cylinder. Moving rasp bars or rub bars pull the crop through concaved grates that separate the grain and chaff from the straw. The grain heads fall through the fixed concaves. In most modern combines, the grain is transported to the shoe by a set of 2, 3, or more augers.

The straw walkers are located above the sieves, and also have holes in them. Any grain remaining attached to the straw is shaken off and falls onto the top sieve. There are usually two sieves, one above the other. The sieves and basically a metal frame, that has many rows of "fingers" set reasonably close together. The angle of the fingers is adjustable as to change the clearance and control the size of the material passing through. Heavy material, e.g., unthreshed heads, fall off the front of the sieves and are returned to the concave for re-threshing.
