The Combine Harvester Divider Assembly (also known as the crop divider or divider point) is the very first point of contact between the harvester and the field crop. Located at the extreme left and right front ends of the header, it is the V-shaped or pointed structure that separates the crop to be harvested from the standing crop that will be left behind. Consisting of a main body, support structures, mounting bases, and various fasteners, it guides the crop smoothly into the reel and cutter bar.
What Does the Divider Assembly Do?
The performance of the divider assembly directly affects the operating efficiency of the harvester header, the crop loss rate, and the machine’s ability to handle lodged crops.
| Function | Description |
| Separating Crop | Cleanly divides the standing crop from the uncut crop, preventing the header from dragging or pushing down the crop on the edges. |
| Guiding Crop | The forward-extending design gently guides the crop stalks backward into the reel and cutter bar for a clean cut. |
| Lifting Lodged Crop | For crops that have fallen over, the pointed tip slides underneath the stalks, lifting them up so they can be cut rather than missed. |
| Protecting the Header | Acts as the first line of defense, absorbing impacts from the ground, stones, or hard soil ridges to protect the main header frame. |
| Structural Support | Serves as a mounting point for the outer ends of the header frame and reel structure. |
Main Components of the Divider Assembly
The divider assembly is the “protective beak” and guiding component of the header. Because the left and right sides have different structural and mounting requirements, they are usually supplied as independent components. Maikeyier provides one-stop supply services for both divider assemblies across various harvester models, including all bolts, washers, and brackets, saving you the trouble of sourcing small hardware separately.
Left Divider Assembly (Left Side)
The left divider assembly typically includes the main body, left-specific support bracket, mounting base, and a complete set of fasteners, ensuring it is ready to install right out of the box.
| Component | Description | Quantity |
| Left Divider Assembly | The main V-shaped body for the left side | 1 |
| Left Support | Structural support bracket | 1 |
| Left Divider Mounting | Base for mounting to the header frame | 1 |
| Hex. Rod Welding | Reinforcing rods for structural integrity | 3 |
| Hex. Head Bolt with Washer | Used for securing the main body | 2 |
| Hex. Head Bolt | Used for mounting brackets | 6 |
| Hex. Head Bolt | Used for mounting base | 4 |
| Hex. Head Bolt | Additional securing bolts | 3 |
| Hex. Head Bolt with Washer | Securing the support structure | 1 |
| Standard Spring Washer | Prevents loosening under vibration | 8 |
| Plane Washer | Distributes pressure | 12 |
| Big Gasket | Heavy-duty fastening for the base | 4 |
Right Divider Assembly (Right Side)
The right divider assembly is symmetrical to the left side but is equipped with right-side specific mounting brackets and hardware.
| Component | Description | Quantity |
| Right Divider Assembly | The main V-shaped body for the right side | 1 |
| Right Support | Structural support bracket | 1 |
| Right Support Mounting | Base for mounting to the header frame | 1 |
| Hex. Head Bolt with Washer | Used for securing the main body | 2 |
| Hex. Head Bolt with Washer | Securing the support structure | 6 |
| Hex. Head Bolt | Used for mounting brackets | 5 |
| Hex. Head Bolt | Used for mounting base | 4 |
| Hex. Head Bolt | Additional securing bolts | 3 |
| Standard Spring Washer | Prevents loosening under vibration | 6 |
| Plane Washer | Distributes pressure | 7 |
| Big Gasket | Heavy-duty fastening for the base | 4 |
Common Faults and Replacement Signals
Because dividers are at the very front of the machine, they take a severe beating. When they fail, it directly impacts the harvester’s cutting width and grain loss rate.
| Fault Symptom | Possible Cause | Components to Check |
| Uneven stubble, edge crops pushed over | Divider tip bent, deformed, or installed at the wrong angle | Main Divider Body, Mounting Base |
| Crop wrapping around the divider | Divider surface damaged, or crop is too wet and viney | Divider Body, Support Rods |
| Severe vibration at both ends of the header | Loose mounting bolts or cracked welds on the support brackets | Left/Right Support, Hex. Head Bolts |
| Divider digging into the soil | Header height set too low, or mounting bracket bent | Divider Mounting, Support Base |
| Divider assembly falls off | Fastener failure (sheared bolts or missing washers) | All fasteners (Spring washers, Big gaskets) |
How to Choose the Right Divider Assembly Replacement Parts
Different brands and models of headers have variations in the angle, length, and mounting hole spacing of the dividers. Before purchasing, always match according to the machine models and part numbers currently in use and sold in your market. Or send us photos of the harvester parts you need, and we will help you match them.
Confirm Model and Header Width
- Harvester brand and model (e.g., Kubota DC70, Yanmar AW70V, Lovol RG50).
- Header width (2.0m, 2.5m, etc.).
- Part number (OEM number) of the divider assembly.
Confirm Replacement Scope
- Complete Left/Right Assembly: Divider body + support + mounting base + all hardware.
- Single Divider Body: Just the V-shaped metal body.
- Mounting Base/Support: The brackets connecting the divider to the header.
- Hardware Kit: Bolts, nuts, washers.
Confirm Material and Process
- Standard Material: Q235 or Q345 steel plate. Suitable for standard operating conditions.
- High-Strength/Wear-Resistant Material: Some models use wear-resistant steel (such as NM400) at the tips to handle rocky or hard soil conditions.
- Welding Quality: Check whether the welds on the support rods and mounting brackets are full and complete. Maikeyier uses robotic and CO2 welding to ensure maximum strength.
