Most people think that tractor implements should be made entirely or almost entirely of steel. The reason for using steel is that it is the ideal material for withstanding the forces and stresses involved in equipment such as disks, brush hogs, and buckets, used for cutting, mowing, scooping, digging, etc. However, the main functions of the Front End Carrier are lifting, carrying, dumping, etc., which incur much different kinds of force and stress. The stresses on the Carrier are really more like those on a farm wagon or trailer, than on a brush hog or disk. And of course, farm wagons and trailers often use wood planks.
