Farms warned of heatwave fire risk from tractor and telehandler faults 

The UK’s record-breaking summer has dramatically increased the risk of fires caused by otherwise minor faults in tractors, telehandlers, and other agricultural vehicles. 

That’s the assessment of CFTS, the voluntary accrediting scheme for LOLER and PUWER Thorough Examination providers, as it urges farmers and agricultural engineers to ensure every machine has been thoroughly checked. 

Overheating, degradation, and fire risk 

According to NFU Mutual, machinery fires cost UK farms an estimated £37m, even without 2026 heatwave conditions.  

But, as temperatures soared earlier in the year, CFTS examiners reported a surge in wear and degradation to key parts and materials including hoses, seals, hydraulic systems, and electrics — all areas where an undetected issue can pose a fire risk. 

Meanwhile, extreme temperatures multiply the risk from even small leaks, material buildup, or debris. 

With the Met Office saying a further heatwave could coincide with harvest, CFTS believes this is a critical moment to confirm any telehandlers, tractors, and other machines have been properly tested.  

CFTS Director Rob Fisher says: “The best time to have your vehicles inspected was before the heatwave began. The second-best time is now. 

“This extreme summer has pushed many components and compounds to the limit and beyond. It’s a situation where even a small flaw can have disastrous consequences — including fire.”  

Accident and downtime risk also high 

Alongside the elevated fire risk, the CFTS warning covers several further heat-related issues that could cause accidents and downtime: 

• Overheating in engines, hydraulic systems, and drive units 

• Accelerated tyre degradation and pressure imbalances 

• Brake fade due to higher operating temperatures 

• Hydraulic fluid breakdown 

Whole-machine inspection essential 

Crucially, the warning extends beyond the lifting components commonly inspected under LOLER tests, to include the whole machine. 

Rob Fisher explains: “A LOLER inspection is a good start, but in many cases that only tests lifting components. Many of the greatest risks involve tyres, brakes, and electrical systems — things that are overlooked disturbingly often in LOLER tests. 

“Our strong advice is to check whether your last LOLER examination covered lifting parts only. If so, book a Thorough Examination that covers you for LOLER and PUWER together, so you know the whole vehicle is safe to use. Your local CFTS member will be able to help.”
