Driving impression: JCB Loadall 536-70 Agri Xtra Back at the 2007 SIMA show, JCB introduced a fifth side-engined model to its Loadall range, a 7m machine with the capacity of a 3.6t handler but the build of a four-tonner. And for buyers who want even greater choice, there are four spec levels from which to pick. Martin Rickatson drives the ‘flag’ version of the 536-70
