Wider combine headers may be great for covering the ground, but towing them is becoming a bit of a nightmare, as many a visitor to Cereals 2014 could testify.

But for anyone who routinely takes long headers around mini-roundabouts or through tight field gateways, help is at hand in the form of four-wheel steer header trailers such as this Zurn unit (pictured). It has all-wheel steering, with the back axles turned by the front one via long bars.

It’s also very strong, which is important if you have a heavy header such as Deere’s PremiumFlow. The cost of this unit is £10,500 and it comes with overrun brakes Austrian maker Biso has also tackled the problem with a new Profi Trolley unit that uses a hydraulically steered rear axle and overrun brakes on all four wheels.

The new range of header trailers goes from 6.7-16m with Profi steering available from 9m upwards.

All trailers are fitted with lights and high-spec running gear, including commercial brakes.

Biso, which is brought into the UK by Essex-based Abrey and Son, says it can supply steel headers up to 9m and aluminium headers up to 12.3m for all popular makes of combines.
