Case IH combines are renowned for their advanced agricultural technology, designed to maximize efficiency and productivity during the harvesting process. These machines are essential for large-scale farming operations, combining cutting-edge engineering with robust construction. This article delves into the key components of Case IH combine, explaining their functions and significance in the harvesting process.

Overview of Case IH Combine

Case IH, a brand of CNH Industrial, produces a range of agricultural equipment, including combine. Combine are complex machines that integrate various functions such as reaping, threshing, and winnowing into a single operation, streamlining the harvesting process. Case IH combine are known for their reliability, efficiency, and advanced features that cater to modern agricultural needs.

Major Parts of Case IH Combines and Their Functionality


Function: The header is the front part of the combine and is responsible for cutting and gathering the crops. Different types of headers are available for various crops, including grain headers, corn headers, and draper headers.


Grain Headers: Designed for wheat, barley, and other small grains.

Corn Headers: Specifically for corn, with snapping rolls to pull the stalks down and strip the ears off.

Draper Headers: Utilize a conveyor belt system for smooth and gentle handling of crops, ideal for soybeans and canola.

Threshing System

Function: Separates the grain from the stalk and chaff. This process involves rubbing, beating, and squeezing the crops to release the grains.


Rotor: The main component that performs the threshing. Case IH combine often features a single or dual rotor design that ensures gentle yet effective threshing.

Concaves: Curved metal grates that work in conjunction with the rotor to separate grain from the stalk.

Cleaning System

Function: Removes chaff and other impurities from the grain after threshing.


Sieve: Series of perforated screens that filter the grain based on size.

Fan: Blows air through the sieves to lift and separate lighter materials like chaff from the grain.

Grain Handling System

Function: Collects, augers, and stores the cleaned grain.


Grain Tank: Stores the cleaned grain until it can be unloaded.

Unloading Auger: Transfers grain from the tank to a truck or trailer for transportation.

Straw Management System

Function: Deals with the leftover straw and chaff after the grain has been separated.


Chopper: Cuts the straw into smaller pieces.

Spreader: Distribute the chopped straw evenly across the field or place it into windrows for baling.

Operator Cab

Function: Provides the operator with controls and monitoring systems to manage the combine’s functions efficiently.


Control Console: Centralized controls for all combine functions.

Display Monitors: Real-time data on the combine’s performance and grain quality.

Comfort Features: Climate control, ergonomic seating, and visibility enhancements for operator comfort and efficiency.

Engine and Drive Systems

Function: Powers the combine and ensures mobility and operational capability.


Engine: High-performance diesel engines that provide the necessary power for all combine functions.

Hydrostatic Drive System: Allows for variable speed control and smooth operation across various field conditions.


Case IH combines are a testament to the advancement in agricultural machinery, integrating numerous sophisticated parts and systems to facilitate efficient and effective harvesting. From the versatile headers to the powerful threshing and cleaning systems, each component plays a crucial role in ensuring that the harvesting process is streamlined and productive. Understanding these parts and their functions can help operators maximize the performance and longevity of their combines, ultimately contributing to better harvest outcomes.
