ABSTRACT:
A boom assembly for a loader that is pivotally mounted on a tractor. The assembly includes a pair of boom arms which are pivotally connected at one end of the tractor. The arms are fabricated from two C-channels which are welded together. The arms have aligned inside apertures sized to accept a tube which is rigidly connected to both channels. The assembly is completed when a cross tie member envelopes the tubes and is rigidly secured to the inner C-channels.
