Early development of hydraulic systems for what would become the backhoe loader proceeded in parallel in the US and the UK. The invention of the first backhoe swing frame was developed in July 1947 by Vaino J. Holopainen (pronounced "Waino") and Roy E. Handy Jr. (thus the company name "Wain-Roy") and assigned to Wain-Roy Corporation of Hubbardston Massachusetts United States. In July 1948 patent # 2698697 was filed by Vaino J. Holopainen. The swing frame breakthrough allowed the hydraulic digging arm to swing to the side to dump the bucket. This patent also included the invention of the out-rigger bar and high flow control. In April 1948 Wain-Roy Corporation sold the very first all hydraulic backhoe mounted to a Ford Model 8N tractor to the Connecticut Light and Power Company. Wain-Roy made 24 units in 1948. Wain-Roy also made them for Sherman Products of Royal Oak Michigan and Ford. Approximately 7000 Wain-Roy Backhoes were manufactured and sold between the fall of 1948 and early 1954 mainly through Ford dealers.
The first hydraulic wheel loader was invented by Frank G. Hough in the mid-1940s under patents 2782946 and 2726778. The first Tractor Loader Backhoe was a Wain-Roy backhoe mounted to a Frank G. Hough model "HE" in 1952 in Holden Massachusetts US for the Holden Water Department. The F.G. Hough Company was a subsidiary of the International Harvester Company. By early 1954 two Hough "Payloader" model wheel loaders the HE and the HF were available with Wain-Roy backhoes. In 1954 Wain-Roy Corporation got a deal with IH for the Hough TLB full-scale production on several other models of Hough loaders.
In the same year 1948 JCB launched the first European hydraulic loader and followed that in 1953 with a backhoe with a 180° slew fitted to a tractor. Then in 1957 while Case produced the first "integrated" Tractor Loader Backhoe in 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).4 In 1965 they would follow this with the worlds first 360° excavator.
