Is your tractor lifting poorly, the steering feeling stiff, or the tipping system refusing to work?
Is your tractor lifting poorly, the steering feeling stiff, or the tipping system refusing to work? You might be facing one of the most common hydraulic failures in agricultural machinery — problems that can often be diagnosed and fixed faster with JALTEST INFO WEB.
With modern tools like JALTEST INFO WEB for agricultural machines, it’s now possible to identify the exact cause of a malfunction — without wasting hours disassembling the system unnecessarily.
1. A System as Essential as It Is Complex
The hydraulic system is the heart of tractors and agricultural machines.
It converts fluid pressure into mechanical power for lifting, steering, or pulling.
What makes it special?
- It operates at very high pressure (up to 300 bar).
- It reacts to the slightest impurity in the oil.
- It requires regular maintenance and calibration.
⏱️ Average time for a full diagnostic: 30 to 60 minutes with JALTEST INFO WEB.
2. The Essential Components of the Hydraulic System
Key elements to monitor include:
- Hydraulic pump: provides system pressure.
- Cylinders: control movement.
- Valves and distributors: direct fluid flow.
- Filter and oil tank: keep the hydraulic fluid clean.
- Hoses: connect and route the system.
💡 Jaltest Tip: If a hose is leaking, JALTEST INFO WEB for agricultural machines provides the correct disassembly steps and torque specifications for replacement.
4. Steps for Hydraulic Diagnosis and Repair
1️⃣ Observe the symptoms: power loss, oil leaks, unusual noise.
2️⃣ Connect to JALTEST INFO WEB: select the tractor model and view the fault codes.
3️⃣ System analysis: follow the interactive hydraulic diagrams to locate the faulty component.
4️⃣ Manual verification: check oil level, filter cleanliness, and hose condition.
5️⃣ Repair and calibration: replace faulty parts following guided procedures, then recalibrate the system.
⚙️ Pro Tip: Save your diagnostic report in JALTEST INFO WEB to keep a record of all repairs and interventions.
5. Assembly and Prevention
Once the issue is fixed, bleed air from the circuit and test each cylinder under no-load conditions.
🧰 Good practice: Record the machine’s engine hours and schedule the next maintenance session in JALTEST INFO WEB for agricultural machines to prevent the same failures from happening again.
6. Storage and Preventive Maintenance
- Store hydraulic hoses away from heat sources.
- Check oil viscosity every 500 hours of use.
- Clean the suction filter regularly.
Thanks to the “maintenance history” feature in JALTEST INFO WEB, you can anticipate upcoming services before a failure occurs.
7. Common Types of Hydraulic Failures
🔹 Seal or cylinder leakage
🔹 Pressure drop caused by a worn pump
🔹 Clogged filter
🔹 Air trapped in the hydraulic circuit
Each cause can be isolated using JALTEST INFO WEB diagnostics, which display the fault code and the correct procedure according to the machine’s brand (John Deere, New Holland, Fendt, etc.).
8. Conclusion – Anticipate, Don’t Endure Hydraulic Failures!
Agricultural hydraulic failures aren’t inevitable.
With a smart tool like JALTEST INFO WEB for agricultural machinery, every issue becomes an opportunity to optimize your machines.
👉 Less downtime, more productivity, and tractors always ready to work.
