Ferguson's concept was to combine a link via two lower and a single upper raise arms that were linked to a hydraulic lifting ram.

Their reasonably modest frames and specific controls make backhoe-loaders extremely helpful and common in urban engineering projects, which include design and repairs in spots much too smaller for much larger devices.
