Hydraulically extending axles are a common sight on Dutch slurry tankers to spread the weight when travelling on soft land, but the use of such a system on a self-loading forage wagon is believed to be a world first. The result of modifications to a Vicon forage wagon by Dutch engineering company Rosier Greidanus, the axle extends by 75cm each side to ensure the front wheels run in separate tracks to the rear ones.

Owned by Dutch contractor Vollenhove, the modification increases the weight of the axle by around 450kg, and Wietze Rosier and Siebren Greidanus, the two owners of the Dutch engineering company, reckon it is possible to develop a system for other makes of forage wagon. The company has already added a similar concept to over a dozen Zunhammer slurry tankers.
