Case Study: Landini 5H-110 Hydraulic Repair

Specialist Diagnostics Get a Tractor Lifting Reliably Again

At Farm and Fleet Services, we know that hydraulics you can't trust turn every job into a gamble. As the trusted machinery specialists for Cornwall and West Devon, we take real pride in prompt response, honest diagnosis and repairs built to last. This job showed exactly how the right diagnostic technology, paired with hands-on know-how, gets to the truth fast — and here's how we got a hardworking Landini 5H-110 lifting confidently once more.

The Problem

The customer got in touch with a frustrating fault: the hydraulics wouldn't raise or lower correctly. For a tractor relied on day in, day out, hydraulics that won't behave are more than an annoyance — they slow every task, from hitching implements to working the land, and can quickly cost real time. Understanding just how much rests on a dependable machine, our team set to work getting straight to the root of it.

The Diagnosis

Hydraulic faults can have any number of causes, so guesswork simply won't do. Rather than stripping parts on a hunch, our engineer connected the Argo Diagnostic tool — the specialist system built specifically for these machines — to read exactly what the tractor was telling us.

That's where technology earns its keep. The diagnostic quickly pinpointed the culprit: a faulty hitch height potentiometer. This small but vital sensor tells the system where the hitch actually is, and when it fails, the hydraulics lose their sense of position — which explained precisely why the machine wouldn't lift or drop as it should. A clear, accurate read meant we identified the fault straight away, with no unnecessary work and no shortcuts.

The Solution

With the fault confirmed, our team carried out a thorough, lasting repair:

• Replaced the faulty hitch height potentiometer with a quality part to restore accurate position sensing
• Calibrated the new sensor using the Argo Diagnostic tool, so the system read the hitch position exactly right across its full range
• Checked the hydraulics through raise and lower to confirm smooth, reliable operation

Fitting the part is only half the job — without proper calibration, the system can't work as it should. Using the same specialist tool to set everything up correctly meant the customer got a repair that performs perfectly, first time.

The Result

The Landini 5H-110 was returned to work with the hydraulics raising and lowering smoothly and accurately once more. Just as importantly, the customer left with complete confidence that the job had been done properly — no return trips to the workshop and no lingering doubts out in the field.

Why Professional Servicing Pays

A fault like this can be near impossible to pin down by eye alone, which is exactly why the right diagnostic technology matters. There's genuine value in trusting your machinery to people who have both the specialist tools and the expertise to use them well. Our precise, technology-led approach meant we found the exact cause quickly, fitted only what was needed and calibrated the repair to a proper finish — sparing the customer wasted time and unnecessary cost.
