2. Installation

Proper installation of the threshing tines is critical for safety and optimal combine performance. It is recommended that installation be performed by qualified personnel familiar with agricultural machinery maintenance.

2.1 Safety Precautions

• Always ensure the combine is turned off, engine is cool, and all power is disconnected before beginning any maintenance or installation.
• Engage parking brake and block wheels to prevent accidental movement.
• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
• Refer to your John Deere combine's official service manual for specific safety procedures and detailed instructions related to the threshing system.

2.2 Installation Steps (General Guidance)

1. Locate the existing threshing tines within the combine's threshing cylinder or rotor.
2. Carefully remove the worn or damaged tines by unfastening their mounting bolts. Note the orientation of the old tines.
3. Clean the mounting area thoroughly to remove any debris or residue.
4. Position the new Separator Threshing Tine, ensuring correct alignment with the mounting holes.
5. Secure the tine using appropriate fasteners, tightening them to the manufacturer's specified torque settings (refer to your combine's service manual).
6. Repeat for all tines being replaced.
7. After installation, manually rotate the threshing cylinder/rotor (if safe and possible) to ensure free movement and proper clearance of the newly installed tines.

Note: For specific threshing element positions, refer to the following part numbers for other components:

• For threshing element 1st position: use part 163265
• For threshing element 2nd position: use part 156588
• For threshing element positions 3, 4, 5: use part 150895

3. Usage Guidelines

The number of Separator Threshing Tine Kits required depends on the crop being harvested:

• For Grain/Corn: 8 sets of tines are typically required for optimal threshing performance.
• For Rice: 9 sets of tines are typically required for optimal threshing performance.

Always ensure the correct number of tines are installed for the specific crop to maximize efficiency and minimize grain damage or loss.

4. Maintenance

Regular inspection and maintenance of your threshing tines will extend their lifespan and ensure consistent performance.

• Daily Inspection: Before each use, visually inspect all tines for signs of wear, bending, cracks, or damage.
• Cleaning: After each harvesting season or as needed, thoroughly clean the threshing cylinder/rotor and tines to remove accumulated crop residue, dirt, and moisture. This prevents corrosion and maintains balance.
• Fastener Check: Periodically check the tightness of all mounting bolts. Loose fasteners can lead to premature wear or failure.
• Replacement: Replace tines immediately if significant wear or damage is observed. Operating with worn tines can reduce threshing efficiency, increase grain loss, and potentially damage other combine components.
