Mobile diesel tank options and prices for farm machinery

Options for getting fuel to thirsty machinery out in the field range from purpose-built trailed bowsers to a tank in the back of a pickup, strapped on to a flatbed trailer, carried on a three-point hitch or even built into a tractor’s front-mounted ballast box.

Portable tank systems typically come with a 4m cable to reach a vehicle battery to power an electric pump of roughly 40-litre/min capacity; upgrades of 50-litre/min or more are available as options.

They can be purchased online, as well as through dealers and distributors.

For delivery, a 4m hose – mostly fitted with an auto shut-off nozzle to minimise the risk of spillage – is the norm.

Flow meters to record individual machine fill-ups are also on most manufacturers’ options list.

Practical or nominal capacity is about 95% of the quoted tank volumes.

Double-skinned, plastic-in-steel and steel-in-steel structures provide a 110% anti-leakage bund, essential for transporting diesel on public roads.

Rules and regulations

Manufacturers’ product information for mobile tanks of 200 litres or more (generally described as IBCs up to 3,000-litre capacity) refer to “UN type approval” and “ADR certified”.

The latter relates to a European agreement on the carriage of dangerous goods by road.

Certification indicates that the containers are approved for transporting diesel on public highways.

To retain this certification, the containers must be inspected and pressure tested every two and half years from manufacture.

An internal inspection that includes metal thickness measurement of steel tanks is also required every five years. 

Chris Ford, of Wilts-based Tank Services, highlights that the five-year “MOT” provides a good opportunity to have the tank professionally cleaned inside and out.

Steel tanks can have continued use, as long as they pass the certification requirements.

However, all-plastic and plastic containers within a steel shell may not be used to transport diesel on the road after five years from manufacture.

Containers of less than 200-litre capacity need not be bunded and are exempt from ADR/UN certification requirements.

But they must be “fit for purpose” – in other words, designed and equipped for transporting diesel securely.

For operators, special training and licensing as a “dangerous goods vehicle driver” only kicks in when transporting quantities of more than 1,000 litres of diesel on public roads.

Information on training course providers and certification forms can be found on the website.
