When dealing with hydraulic malfunctions on a John Deere 35 or any hydraulic system, it's important to approach the issue systematically. Here are some techniques you can try to diagnose and fix hydraulic malfunctions:

Hydraulic malfunctions on a John Deere 35

1. Check hydraulic fluid levels: Ensure that the hydraulic fluid level is within the recommended range. Low fluid levels can cause various hydraulic problems. If the level is low, add the appropriate hydraulic fluid to bring it to the required level.
2. Inspect for leaks: Look for any visible leaks in the hydraulic system. Leaks can cause a loss of hydraulic pressure and result in malfunctions. Check all hoses, connectors, seals, and fittings for signs of leakage. Replace or repair any damaged components.
3. Clean or replace hydraulic filters: Dirty or clogged hydraulic filters can restrict the flow of hydraulic fluid and cause malfunctions. Check the condition of the filters and clean or replace them as necessary. Follow the manufacturer's recommendations for the correct filter type and replacement intervals.
4. Check hydraulic lines and connections: Inspect the hydraulic lines and connections for any signs of damage or loose fittings. Tighten loose connections and replace damaged or worn-out hoses or lines.
5. Test hydraulic pressure: Use a hydraulic pressure gauge to measure the pressure in the system. Compare the readings to the specifications provided by the manufacturer. If the pressure is outside the recommended range, it may indicate a problem with the pump, relief valve, or other components.
6. Inspect hydraulic pump: The hydraulic pump is a critical component that provides pressure to the system. Check the pump for any damage, excessive wear, or leaks. If the pump is not functioning properly, it may need to be repaired or replaced.
7. Bleed air from the system: Air trapped in the hydraulic system can cause spongy or erratic operation. Follow the manufacturer's instructions to bleed the air from the system using the designated bleed valves.
8. Consult the technical manual: Refer to the technical manual specific to your John Deere 35 model for troubleshooting guides, diagrams, and detailed instructions. The manual will provide specific guidance for your equipment and help you diagnose and fix hydraulic issues.
9. Seek professional assistance: If you're unable to diagnose or fix the hydraulic malfunction on your own, it's recommended to contact a qualified technician or John Deere service center for further assistance. They have the expertise and specialized tools to troubleshoot and repair hydraulic systems effectively.

Remember to prioritize safety when working with hydraulic systems. Always follow the manufacturer's guidelines and take appropriate precautions to avoid injuries and further damage to the equipment.
