tractor loader การใช้

The Steelfab SF 122 loader was used to build the " Roadless 700 " Tractor loader in 1968.
In North America, this arrangement is often referred to as simply a backhoe or, when on a chassis originally derived from farm tractors, a tractor loader backhoe ( TLB ).
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.
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 ).
