1. Safety first: Ensure the tractor is turned off, the engine is cool, and the hydraulic pressure is released. Wear appropriate safety gear, such as gloves and goggles, to protect yourself during the troubleshooting process.
2. Identify the problem: Determine the specific nature of the hydraulic issue. It could be a loss of hydraulic functions, unresponsive controls, leaking fluid, or unusual noises. Understanding the symptoms will help you narrow down the possible causes.
3. Check the hydraulic fluid level: Inspect the hydraulic fluid reservoir or tank to ensure it has an adequate amount of clean fluid. Low fluid levels can cause various hydraulic problems. If needed, add the recommended hydraulic fluid to the appropriate level.
4. Inspect for leaks: Examine the hydraulic hoses, connections, and fittings for any signs of leakage. Leaks can result in a loss of hydraulic pressure. If you find any leaks, identify the source and repair or replace the affected components as necessary.
5. Verify the hydraulic filter: Clogged or dirty hydraulic filters can restrict fluid flow and lead to pressure issues. Locate the hydraulic filter(s) and inspect them. If they are dirty or clogged, replace them with new filters.
6. Check the hydraulic pump: The hydraulic pump generates pressure in the system. Listen for unusual noises or vibrations when the system is activated. If there are any issues, such as noise or lack of pressure, the pump may need to be repaired or replaced.
7. Inspect control valves: Faulty control valves can cause erratic or unresponsive hydraulic operations. Check the valves for damage or signs of wear. Clean or replace them as needed.
8. Verify hydraulic cylinders and hoses: Inspect the hydraulic cylinders and hoses for damage, leaks, or blockages. Damaged cylinders or hoses may need to be repaired or replaced.
9. Check the hydraulic system connections: Ensure all hydraulic connections are secure and tight. Loose or improperly connected components can result in fluid leaks or pressure loss.
10. Consult the tractor's manual or seek professional help: If you're unable to identify or resolve the hydraulic issue, refer to the tractor's manual for specific troubleshooting steps. If the problem persists, it's advisable to seek assistance from a qualified technician or contact the New Holland service center for guidance tailored to your TM135 tractor model.

These steps provide general guidance for troubleshooting hydraulic issues on a New Holland TM135 tractor. Always refer to the tractor's manual and follow the manufacturer's guidelines for accurate troubleshooting and resolution of specific problems.
