A Rare Find: Rebuilding a Cab-less Massey Ferguson 5455 for Specialist Work


This month, we’ve had a Massey Ferguson 5455 in for a major overhaul, but not your typical 5455. This one is cab-less, and tractors like it are becoming increasingly hard to find here in the UK.


Why a Cab-less Tractor?


The customer uses the tractor inside polytunnels, where space is tight, and manoeuvrability is everything. A tractor with this horsepower, size, and the ability to work safely under cover without a cab roof catching or restricting movement is a rare and valuable tool.


Rather than replacing it, the owner chose to invest in a full rebuild, extending its working life for many years to come.


A Complete Transformation in the Workshop


Over the past month or so, our technician Wayne has carried out an extensive list of repairs, upgrades, and refurbishments to bring this machine back to top condition.


Rebuilt Dyna-4 Gearbox


The heart of the tractor needed attention, so we stripped and rebuilt the Dyna-4 gearbox to ensure smooth gear changes and reliable operation during stop-start work in tight environments.


Forward & Reverse Clutch Pack Rebuild


Essential for quick directional changes, especially in confined spaces, the shuttle clutch pack was fully rebuilt for crisp, dependable engagement.


New Rear Fenders


The old fenders were damaged and tired, so a brand-new set was fitted to improve safety and appearance.


New Plastic Side Panels & Dash Panels


A fresh set of panels not only sharpens the look but also protects vital components from dust, rain and debris, vital for a tractor with no cab to protect it from the elements.


New Operator Switches


With many original switches worn out, we replaced them all to ensure full functionality and reliability.


New Seat


A comfortable operator is a more productive operator; the new seat modernises the driving experience and provides much-needed support.


Full Linkage Rebuild


The rear linkage system was completely rebuilt using new components throughout, restoring accuracy and lifting performance.


New Front Diff & Pivot Housing


Worn splines in the front differential meant it was time for a replacement. We also fitted a new pivot housing to restore smooth steering and front-end durability.


New Pivot Bushes


Fresh bushes ensure proper articulation at the front axle, reducing wear and improving handling.


Full Service


The tractor received fresh engine oil, filters, and a complete inspection — the finishing touch to the mechanical overhaul.


General Tidy-Up & Freshen-Up


Finally, we gave the machine a full tidy-up to make sure it not only works like new but looks the part too.


Keeping Specialist Machines Working for Specialist Jobs


This rebuild will give the tractor a new lease of life and keep it working efficiently inside the customer’s polytunnels for many more seasons.

The Importance of Regular Servicing: A Small Filter, a Big Difference At JJ Farm Services, we understand the importance of regular maintenance in keeping your machinery reliable and efficient. We were reminded of this recently during a routine tractor service, when we replaced the air filters and discovered the outer one was covered with dust and debris. It looked like it hadn’t been changed in quite some time! While it might not seem like a major issue, a clogged air filter can have a big impact. It restricts airflow to the engine, causing it to work harder, burn more fuel, and lose power. Over time, that strain can lead to costly wear and repairs — all from a part that’s designed to be regularly replaced. Why Regular Servicing Matters Protects your engine – Clean filters and quality oil keep harmful dirt and contaminants out. Improves efficiency – A well-serviced engine runs smoother and uses less fuel. Prevents downtime – Regular checks catch small issues before they cause breakdowns. Maintains value – Service history shows your machine’s been properly cared for, helping protect resale value. Don’t Wait Until It’s Too Late It’s easy to overlook routine maintenance when everything’s running fine, but prevention is always better than repair. A simple service can make a huge difference to performance, reliability, and running costs. If it’s been a while since your tractor was last serviced — or you’re not sure when those filters were last changed — now’s the perfect time to book in.
