Hydraulic failure on a Fendt 412 tractor

1. Identify the symptoms: Gather information about the specific symptoms of the hydraulic failure. Understand which hydraulic functions are affected and any other relevant details.
2. Check hydraulic fluid level: Ensure that the hydraulic fluid reservoir is filled to the recommended level. Low fluid levels can cause hydraulic malfunctions. If the level is low, refill it to the proper level and check for any leaks.
3. Inspect hydraulic hoses and connections: Visually inspect all hydraulic hoses and connections for leaks, damage, or loose fittings. Tighten any loose connections and replace any damaged hoses.
4. Check filters and screens: Clogged or dirty hydraulic filters and screens can restrict fluid flow and cause problems. Inspect and clean or replace the filters and screens as necessary.
5. Test hydraulic functions: Operate the hydraulic functions to identify the specific areas where the failure is occurring. Note any unusual noises, slow operation, or failure to respond as expected.
6. Check for air in the system: Air in the hydraulic system can cause spongy or inconsistent operation. Bleed the system to remove any air bubbles, following the instructions provided in the tractor's manual.
7. Inspect hydraulic pump and drive: The hydraulic pump is responsible for generating the necessary pressure for proper hydraulic system operation. Inspect the pump and its drive mechanism for any damage or wear. If necessary, consult the tractor's manual for specific guidance on troubleshooting the pump.
8. Test pressure and flow: Use pressure gauges to measure the hydraulic system's pressure and flow rate. Compare the values to the manufacturer's specifications. Deviations from the recommended values may indicate a problem with the pump, valves, or other components.
9. Check the hydraulic control valves: Inspect the hydraulic control valves for any signs of damage or malfunction. Ensure that the valves are clean and functioning properly. Replace or repair any faulty valves as needed.
10. Consult technical documentation: Review the Fendt 412 tractor's technical documentation, including the operator's manual, service manual, or any troubleshooting guides provided by the manufacturer. These resources may offer specific guidance for diagnosing and repairing hydraulic issues.
11. Seek professional assistance if needed: If you're unable to diagnose or resolve the hydraulic failure on your own, or if the repairs required are beyond your expertise, it's advisable to consult a qualified mechanic or contact the Fendt dealership for professional assistance.

Please note that this is a general guide, and it's important to consult the tractor's manual or seek professional assistance for specific instructions and troubleshooting steps for your Fendt 412 tractor.
