Danish Lamma debutant Stoneless unveiled its ATV-towed rock-picking machine that has apparently proved popular with farmers in its home market.

The trailer carries a Honda petrol engine that powers the hydraulic motor required for several cradle and bed-tip controls.

The dimensions allow for a stone of up to 50cm diameter to be grabbed and loaded into the galvanised bed. Anything that is too big can simply be carried with the claw on the front.

Empty weight of the trailer is 400kg and a typical ATV is about the same, which makes the outfit relatively lightweight compared with roping in a telehandler for the job. Stoneless reckons it can handle boulders of up to 300kg.

It costs £9,000, which includes shipping from Denmark.
