Launched a couple of years ago, JCB's TM420 was the biggest pivot-steer telehandler the company had ever built, offering a 4t lift capacity and more than 5.4m vertical reach.But it lacked a certain something - power. Though the top-end telescopic TM was designed to offer loading shovel customers a potentially more versatile alternative to conventional clamp climbers, it didn't have the muscle to match.Its 145hp motor was the same unit planted in its smaller, lighter sibling - the TM320S. At 1.7t heavier, the 420 was comparatively under-equipped in the power department and, for salesmen making the argument for the 420 as a shovel substitute, it couldn't compete in the power-to-weight stakes.
