Corn Head Gathering Chains & Sprockets: Factory-Direct Replacement Solutions
Why Your JD 708C Needs Replacement Drive Components
For professional farmers and equipment dealers, harvest season demands zero downtime. The John Deere 708C Corn Head (and the entire 700 series, like the 706C, 712C) relies on robust chain and sprocket systems for peak performance. When it’s time to replace worn-out drive parts, settling for low-quality spares is a risk you cannot afford.
As a dedicated Chain and Sprocket Manufacturer, we provide high-precision, heavy-duty replacements that meet or exceed OEM specifications—directly to you.
This guide outlines the exact parts you need to keep your 708C running efficiently.
CA-Type Steel Agricultural Chains
The Gathering Chain is the most critical and heavily worn component on your corn head, responsible for pulling crop into the feeder house. This is where our CA-Type chains shine.
Model Compatibility: CA620 Chain
| Component Description | John Deere OEM Part No. | Our Replacement Model | Function |
| Gathering Chain Assembly | AXE62423 | Heavy-duty CA 620 Assembly | Feeds crop into the combine |
| Auger Drive Roller Chain | AH222291 | Heavy-duty ANSI 80 Series | Drives the cross auger |
Our CA-Type Chain Advantage: Performance Built to Last
Our manufacturing process focuses on maximizing durability in the demanding, abrasive agricultural environment:
Extreme-Duty Materials
Crafted from premium alloy steel, ensuring high ultimate tensile strength and excellent fatigue resistance.
Precision Heat Treatment
Components (pins, bushings, side plates) undergo specialized heat treatment processes (e.g., Carburizing) for optimal surface hardness and core toughness.
Solid Roller Design
Unlike lighter stamped rollers, our solid rollers offer superior load-bearing capacity and impact resistance, drastically reducing premature chain wear and elongation.
Solid Roller Design
A crucial feature. Chrome plating significantly enhances the pin's surface hardness and lubricity, providing extended wear life and corrosion resistance in dusty, harsh conditions.
Cornhead Gathering Chain Sprocket
Key Gathering Chain Sprockets
The sprockets are just as vital. We supply precision-machined sprockets compatible with both standard and the John Deere RowMax™ upgrade systems.
| Component Description | John Deere OEM Part No. | Our Specifications | Note |
| Lower Drive Sprocket | H85252 | High-wear Steel | Standard lower sprocket |
| Upper Drive Sprocket(Upgraded) | KXE10488 | 8-Tooth Precision Machined | Compatible with the RowMax upgrade |
Note on RowMax™: John Deere's RowMax™ upgrade often replaces the standard 6-tooth sprockets with 8-tooth (KXE10488) versions to extend chain life. We ensure our replacement sprockets are compatible with these upgraded specifications for seamless integration.
Roller Chain Sprockets(Auger Drive)
We also provide the matching sprockets for the internal power transmission systems, such as the Auger Drive:
• Auger Drive Sprocket (AXE15284): Typically a 12-tooth sprocket designed for the ANSI 80 roller chain.
• All sprockets are made from high-grade steel, featuring precise tooth profiles and bore specifications for exact fitment and minimal power loss.

FAQs
Is your CA620 chain compatible with John Deere’s RowMax™ system?
Yes. Our heavy-duty CA620 chain assemblies are fully compatible with all John Deere 700 series corn heads, including those running the RowMax™ 8-tooth sprocket upgrade.
How do I know if I need a Standard or Heavy-Duty replacement chain?
For applications like the 708C Gathering Chain, we only recommend our Heavy-Duty (extreme-duty) CA-Type chain. The harvest environment is too demanding for standard chains. Look for features like solid rollers and hardened pins for maximum longevity.
