Backhoe loader of the backhoe could cause the vehicle to tip, most backhoe loaders use hydraulic outriggers or stabilizers at the rear when digging and lower the loader bucket for additional stability. This means that the bucket must be raised and the outriggers retracted when the vehicle needs to change positions, reducing efficiency. For this reason many companies offer miniature tracked excavators, which sacrifice the loader function and ability to be driven from site to site, for increased digging efficiency. Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs
Backhoe the US (whereby all the components were manufactured and warranted by the same manufacturer), JCB introduced the first dedicated backhoe loader (whereby the loader and backhoe were permanently attached to the chassis, allowing them to be more robust, rather than being demountable accessories for an agricultural tractor). In 1965, they would follow this with the world's first 360° excavator. The patent for the first reversible seat was developed at Wain-Roy by Carroll Arnold and Vaino Holopainen and then filed by Vaino under patent #2,784,768, and in June 1954, Vaino filed patent # 2,781,927 for individually controlled outriggers.
