1984 John Deere JD644C Loader & JD646C Compactor Technical Manual
If you’re working with mid-1980s John Deere heavy equipment, this manual is designed to help you clearly distinguish coverage between the JD644C Loader and the JD646C Compactor before you download. It combines both machines in a single technical reference, making it easier to verify model-specific documentation and shared system architecture.
Variant-driven documentation structure
The content is organized around the two distinct machines rather than treating them as a single platform. Shared design elements are documented where applicable, while systems that differ between the loader and the compactor are addressed in separate sections. This layout helps you quickly identify which information applies to your exact machine.
How the material is structured
The manual follows a professional workshop reference format, grouping technical data, diagrams, and specifications by major systems. Greater depth is provided in areas where the JD644C and JD646C diverge, while common assemblies are documented once to avoid redundancy.
System depth highlights
- Engine and auxiliary system documentation across both models
- Hydraulic system layouts with component-level references
- Transmission, differential, and driveline coverage by machine type
- Brake system documentation reflecting loader vs. compactor differences
- Electrical schematics and connector references
