The first JCB-designed machines arrived in 1971, with the launch of the 413 and 418 models, replacing the former Chaseside models. These shovels featured a cab mounted on the front section of the articulating chassis, to provide the operator with an improved view of the working area. They were also equipped with an oscillating centre pivot, to ensure that all four wheels remained in contact with the ground, delivering maximum tractive effort.
