Single Row Forage Harvester for Corn Harving RXMC-80S RXMC 90 Twin

A single-row forage harvester for corn harvesting is a specialized piece of agricultural machinery designed to harvest forage plants, including corn, for animal feed. Unlike larger, multi-row harvesters, a single-row forage harvester focuses on processing one row of corn at a time, making it an efficient and cost-effective solution for small to medium-sized farming operations.

Purpose and Function: The primary purpose of a single-row forage harvester is to cut and collect the stalks of corn plants, then chop them into small pieces suitable for silage. Silage is a type of animal feed that is fermented and stored in a silo, offering high nutritional value. The process involves:

• Cutting the corn close to the ground to maximize yield.
• Feeding the stalks into a chopping mechanism.
• Blowing the chopped material into a container or directly into a transport vehicle.

Key Features: 

• Adjustable Cutting Heights: Allows the operator to select the optimal cutting height based on crop conditions and desired outcomes.
• Chopping Mechanism: Typically includes a series of knives or blades that chop the corn stalks into small, uniform pieces, essential for quality silage.
• Direct PTO Drive: Powers the harvester directly from the tractor’s power take-off, ensuring efficient operation without the need for additional engines or power sources.
• Discharge Chute: Directs the chopped silage into a trailer or container. Some models allow for chute rotation and angle adjustment to accommodate different storage and transport setups.

Structural Components of Single Row Forage Harvester

A single-row forage harvester is a specialized piece of farm machinery designed for efficiently harvesting forage crops like corn into small pieces suitable for silage. Understanding its structural components is essential for operation, maintenance, and troubleshooting. Here’s an overview of the key structural components of a single-row forage harvester:

1. Cutter Bar: The cutter bar is the initial point of contact with the crop, responsible for cutting the forage at its base. It typically consists of a series of sharp blades that make clean cuts close to the ground, ensuring minimal crop loss.

2. Feed Rollers: After the crop is cut, feed rollers grab and pull the stalks into the machine. These can be rubber or metal and work in pairs to evenly feed the crop into the chopper or cutterhead. Their speed can often be adjusted to match harvesting conditions.

3. Cutterhead or Chopping Mechanism: This critical component chops the forage into small, uniform pieces. It usually comprises a rotating drum or cylinder fitted with knives. The size of the chop is adjustable by changing the speed of the cutterhead or by replacing knives with different sizes.

4. Blower or Fan: Once the forage is chopped, a blower or fan propels the chopped material through the chute and into a collection container or directly onto a transport vehicle. The power and effectiveness of the blower significantly influence the harvester's overall performance.

5. Discharge Chute: The discharge chute directs the flow of chopped forage from the blower to the storage or transport unit. It's often adjustable, allowing the operator to control the direction and distance of discharge.

6. Drive System (PTO Shaft): The power take-off (PTO) shaft connects the harvester to the tractor, transferring mechanical power to operate the harvester’s moving parts. This connection is crucial for the harvester's functionality, as it relies on the tractor for propulsion and power.

7. Frame and Chassis: Provides the structural foundation to which all other components are attached. It must be sturdy enough to withstand the stress of operation and the weight of the harvested forage.

8. Wheels: Support the harvester and allow it to move along the row of crops. The size and type of wheels can affect the harvester's maneuverability and stability, especially on uneven terrain.

Working Principle of the Single Row Forage Harvester 

The single-row forage harvester is an essential agricultural machine used for cutting and processing forage crops like corn into small pieces, making it suitable for silage production. The working principle of a single-row forage harvester encompasses several key steps and utilizes various components to efficiently harvest and prepare crops. Here's an overview of how it works:

Step 1: Cutting the Crop: The harvester is aligned with a row of forage crops. As it moves forward, the cutter bar at the front of the harvester cuts the crops close to the ground. This bar consists of multiple sharp blades or discs designed to make a clean and efficient cut.

Step 2: Feeding the Crop into the Machine: After the crop is cut, it's fed into the machine using feed rollers. These rollers grab the cut stalks and guide them towards the central processing unit of the harvester. The speed and pressure of the feed rollers can often be adjusted to accommodate different crop conditions and ensure a consistent feed rate.

Step 3: Chopping the Crop: The cut forage is then passed into the cutterhead or chopping mechanism, which is the core component responsible for chopping the forage into small, uniform pieces. The cutterhead is equipped with a series of rotating knives or blades. The length of the chopped material can be adjusted by changing the speed of the cutterhead or by using different blade configurations.

Step 4: Propelling the Chopped Forage: After chopping, the forage is propelled through a blower or fan system. This component forcefully blows the chopped forage out of the harvester and into a collection method, such as a trailing wagon or truck. The blower ensures that the forage is quickly and efficiently moved away from the harvester to prevent clogging and maintain a steady flow.

Step 5: Discharging the Chopped Forage: The discharge chute directs the flow of chopped forage from the blower to the storage or collection area. The chute can often be adjusted to control the direction and spread of the discharged material, allowing for even distribution or targeted placement within the collection vehicle.

The entire operation is powered by the tractor's PTO (Power Take-Off), which transfers the tractor's engine power to the harvester. The PTO drive shaft connects the tractor and the harvester, ensuring that the harvester's moving parts, such as the cutterhead and blower, receive the necessary power to function.

Common Troubleshooting of the Single Row Forage Harvester 

Troubleshooting issues with a single-row forage harvester is essential for maintaining efficient operation and minimizing downtime during crucial harvesting periods. Here are common problems encountered with single-row forage harvesters and suggested solutions:

1. Poor Cutting Performance
Causes: Dull or damaged cutter bar blades, improper cutter bar height adjustment.
Solutions: Sharpen or replace the blades to ensure clean cuts. Adjust the cutter bar height according to the crop and terrain conditions.

2. Uneven or Incomplete Crop Feed into the Machine
Causes: Misaligned or worn feed rollers, incorrect speed setting for feed rollers.
Solutions: Check and realign feed rollers. Replace any worn rollers. Adjust the speed settings to ensure uniform feeding of the crop into the machine.

3. Chopper or Cutterhead Clogging
Causes: Overloading of the machine, damp or wet crop conditions, incorrect chop length setting.
Solutions: Avoid overloading the harvester by adjusting the travel speed or the crop intake rate. Wait for drier conditions if possible. Adjust the chop length setting for better processing of the crop.

4. Inconsistent Chop Size
Causes: Dull knives on the cutterhead, improper adjustment of the cutterhead, or inconsistent crop feed.
Solutions: Sharpen or replace cutterhead knives. Check and adjust the cutterhead settings for the desired chop length. Ensure even crop feed into the machine.

5. Excessive Vibration or Noise
Causes: Loose or damaged components, misalignment of the PTO shaft, imbalance in the cutterhead.
Solutions: Inspect the harvester for any loose or damaged parts and secure or replace as necessary. Check the alignment of the PTO shaft. Balance the cutterhead according to the manufacturer's instructions.

6. High Fuel Consumption
Causes: Overloading the harvester, inefficient operation due to poor maintenance, incorrect harvester settings for the crop.
Solutions: Adjust the operation to avoid overloading. Perform regular maintenance checks and servicing. Optimize harvester settings for the specific crop and conditions to improve efficiency.

7. Blower Discharge Issues
Causes: Blockage in the discharge chute, blower fan issues, inadequate blower speed.
Solutions: Clear any blockages in the discharge chute. Inspect the blower for damage and repair or replace as needed. Adjust the blower speed to ensure effective crop discharge.
