An exceptionally versatile tool, the wheel loader has found a use in all phases of construction as well as quarry and aggregate production, material recycling, reclamation, rubbish transfer and heavy mining. BY RICHARD CAMPBELL

Early machines were based largely on agricultural two-wheel drive tractors and operated back-to-front with the lifting arms, or mast, mounted on the tractor’s rear with the machine actually operating in reverse!

The first really commercially-successful purpose-built machines were designed by the  https://contractormag.co.nz/classic-machines/hough/" rel="nofollow - Frank G Hough Compan y, which ultimately became a very important arm of the  https://en.wikipedia.org/wiki/International_Harvester" rel="nofollow - International Harvester Corp , Payline division.

These machines really started making an impact during the late 1940s.

Before too long almost every equipment manufacturer had its own variant of a wheel loader for sale.

https://contrafedupdate.me/2021/06/06/a-most-useful-piece-of-equipment/" rel="nofollow - Wheel loaders from Lorain, Case, Pettibone, Nelson, Thew, Mixermobile, Yale and Michigan filled the marketplace along with Hough.

By the end of the decade, Euclid and Caterpillar joined the market.

Among this plethora of wheel loaders was Tractomotive, a wholly owned division of  https://en.wikipedia.org/wiki/Allis-Chalmers" rel="nofollow - Allis-Chalmers.

Allis-Chalmers had had an association with Tractomotive for a considerable period of time before A-C acquired them outright in 1959.
