ABSTRACT:
A canal trimming machine is disclosed which is designed to trim the bottom and sides of an earthen canal so that the canal may be lined and paved. The machine comprises a frame which extends across the width of the canal and which has propelling tracks at the opposite ends thereof which are driven along the canal in the proper direction and at the proper grade. A trimmer is longitudinally movably mounted on the frame and trims at least one-half of the bottom and a majority of one side of the canal. The trimmer is automatically positioned at the proper grade to ensure that the bottom and sides of the canal will be properly prepared for the lining and paving operation. A rock spreader is also mounted on the frame and trails behind the trimmer to fill low spots in the canal so that an even surface will be provided for the lining and trimming operation.
