Common John Deere Hay Rake Parts and Their Functions
Rake Wheels and Tines
- Rake Wheels: These are circular or semi-circular wheels equipped with tines that sweep across the ground to gather hay. They are typically made of steel or durable composites.
- Rake Tines: Attached to the wheels, tines are flexible or rigid prongs that pick up hay without damaging the stems. They are often replaceable and come in various sizes and shapes depending on the rake model.
Drive System Components
- Drive Shaft: Connects the tractor PTO (Power Take-Off) to the rake, transmitting rotational power.
- Gearbox: Reduces or adjusts the rotational speed and transmits torque to the rake wheels. Commonly includes gear sets and oil seals.
- Universal Joints: Allow for flexible connection between drive components, accommodating movement and misalignment.
Support and Structural Parts
- Frame: The main structure that holds all components in place.
- Folding Arms: Enable the rake to fold for transport and storage.
- Support Springs: Absorb shocks and maintain tension on moving parts.
Hydraulic and Electrical Components
- Hydraulic Cylinders: Assist in folding or adjusting the rake’s working position.
- Hydraulic Hoses and Fittings: Transfer hydraulic fluid to actuate cylinders.
- Electrical Switches and Sensors: Monitor the position and movement for safe operation.
Bearings, Bushings, and Fasteners
- Bearings: Allow smooth rotation of wheels and shafts, reducing wear and tear.
- Bushings: Provide a bearing surface within the pivot points.
- Fasteners: Bolts, nuts, and pins that secure parts together; crucial for safety and performance.
