Harvesting Machines – Overview and Applications

What Are Harvesting Machines?

Harvesting machines are essential agricultural equipment used for collecting crops such as grains, corn, rapeseed, grass, and legumes. Modern technology has automated and accelerated harvesting processes, significantly increasing efficiency and reducing crop losses.

Below is an overview of the most important types of harvesting machines, their functions, and applications.

1. Combine Harvesters

Description and Function

A combine harvester is the most versatile and advanced harvesting machine, performing multiple operations simultaneously: cutting crops, threshing grain, separating chaff and straw, and transporting the yield to the grain tank.

Main Components

• Header – Cuts plants and can have specialized attachments for rapeseed, corn, or soybeans.
• Threshing drum – Separates grains from ears.
• Separator and cleaning system – Removes impurities and transfers clean grain to the tank.
• Straw chopper – Shreds and distributes plant residues on the field or forms windrows for baling.
• Grain tank – Stores grain before unloading into a trailer.

Popular Combine Harvester Models

• John Deere T-Series, S-Series, X9
• Claas Lexion, Tucano
• New Holland CR, CX
• Case IH Axial-Flow
• Fendt Ideal

Applications

✔ Harvesting grains (wheat, barley, rye, oats)
✔ Harvesting rapeseed
✔ Harvesting corn (with a row crop header)
✔ Harvesting legumes

2. Balers and Baler-Wrappers

Description and Function

Balers and baler-wrappers collect and compact straw, hay, or forage into bales.

Types of Balers

• Round balers – Form cylindrical (round) bales.
• Square balers – Produce rectangular bales.
• Baler-wrappers – Simultaneously bale and wrap forage in plastic film for silage production.

Top Manufacturers

• Krone
• Claas
• John Deere
• Kuhn
• Fendt
• New Holland

Applications

✔ Collecting straw after combining
✔ Hay harvesting for animal feed
✔ Silage production from fresh forage

3. Forage Harvesters

Description and Function

Forage harvesters cut and chop green fodder (corn, grass, alfalfa) for silage production. They are equipped with cutting knives and a discharge system that loads chopped material onto a trailer.

Types of Forage Harvesters

• Self-propelled – High-performance machines (e.g., Claas Jaguar, John Deere 8000, Krone Big X).
• Trailed – Smaller machines attached to tractors (e.g., Pöttinger, SIP, Strautmann).

Applications

✔ Corn silage production
✔ Harvesting grass and alfalfa
✔ Producing bulk feed for livestock

4. Agricultural Mowers

Description and Function

Mowers are used for cutting grass, alfalfa, and other forage crops. They can work alone or in combination with tedders and rakes.

Types of Mowers

• Rotary (disc) mowers – Fast and efficient, popular in dairy farms.
• Drum mowers – Provide high-quality cutting and often have conditioners to speed up drying.
• Sickle bar mowers – Simple in construction, commonly used in mountainous areas.

Applications

✔ Cutting grass for hay or silage
✔ Preparing fields for harvesting

5. Rakes and Tedders

Description and Function

• Rakes – Gather hay or straw into windrows, making it easier for balers to collect.
• Tedders – Spread cut grass to accelerate drying.

Types

• Rotary rakes – Fast and efficient, ideal for dairy farms.
• Wheel rakes – Affordable and simple, suitable for small farms.

Applications

✔ Preparing hay and straw for baling

6. Corn and Root Crop Harvesters

Description and Function

Specialized harvesters for corn, potatoes, and sugar beets.

Examples

• Corn harvesters (e.g., Claas, John Deere, Geringhoff) – Use row headers to separate corn cobs from stalks.
• Sugar beet harvesters (e.g., Holmer, Ropa, Grimme) – Extract beets, remove leaves, and store the crop.
• Potato harvesters (e.g., Grimme, AVR, Pöttinger) – Lift potatoes from the soil and clean them.

Applications

✔ Corn grain harvesting
✔ Sugar beet harvesting
✔ Potato harvesting

Summary

Harvesting machines play a crucial role in modern agriculture by increasing efficiency and reducing crop losses. Depending on the type of crop, farmers use combine harvesters, forage harvesters, balers, mowers, rakes, and specialized harvesters. Advanced technology ensures greater precision, lower fuel consumption, and more sustainable farming practices.
