John Deere 1840 Operator's Manual

To calibrate the John Deere 1840 Seeder, start by consulting the operator's manual for specific settings related to your seed type. Conduct a test run by measuring a set area, and adjust the seeder settings according to the seed delivery rate observed. Re-calibrate as necessary to achieve the desired seeding rate.
Pre-season maintenance includes checking for worn or damaged parts, lubricating moving components, ensuring hoses and fittings are leak-free, and inspecting the seed tubes. Replace any parts that show signs of wear and perform a functionality test before use.
If seed distribution is uneven, first check for blockages in the seed tubes and clean them if necessary. Ensure that the seeder is level and the seed meter is properly adjusted. Inspect the drive system for any slippage or mechanical issues.
Inspect the seed meter for debris or worn parts. Clean the meter thoroughly and replace any damaged components. Check the drive system for proper engagement and ensure there are no obstructions in the seed delivery path.
Refer to the operator's manual for a detailed diagram of lubrication points. Common areas include the drive chains, pivot points, and bearings. Use the recommended lubricant type and apply it according to the specified intervals.
Ensure that the seed meter is properly calibrated to avoid excessive pressure. Use the correct seed plates for your seed type and size. Regularly inspect the seed tubes and meters for debris and clean them to prevent blockages.
Inspect the hydraulic hoses and connections for leaks or damage. Check the hydraulic fluid level and top it up if necessary. Test the hydraulic pump and valves for proper operation and consult a technician if issues persist.
Ensure the seeder is properly leveled and the seed meters are calibrated for the specific seed type. Monitor the ground speed to match the seeding rate and adjust row spacing settings as needed for precise seed placement.
Seed bridging can occur due to high humidity or irregular seed shapes. To prevent it, ensure the hopper is dry and use a seed lubricant if necessary. Regularly agitate the seeds during operation to maintain a consistent flow.
Clean the seeder thoroughly to remove any seed residue and dirt. Lubricate all moving parts and ensure the machine is dry before storage. Store it in a clean, dry location and cover it to protect against dust and moisture.
