An apparatus for picking and conveying lumber pieces from the ground for example for removing stacked support lumber during laying of a pi pe line comprises a tracked vehicle carrying a transport conveyer across the re ar of the vehicle and a conveyer table extending from the feed end of the main conveyer forwardly and downwardly toward the ground. At the forward picking end is provided a picker roller for lifting the lumber pieces from the groun d. On one side of the picker roller is provided a drive conveyer which is generall y vertical and driven at a high speed so that ends of the lumber pieces engagi ng the drive conveyer are driven rapidly rearwardly over the picker roller onto the conveyer so as to move along their length. On the side opposite to the drive conveyers provided a vertical flap which can pivot from side to side to push the lumber pieces toward the drive conveyer. The forward end of the conveyer table can be moved vertically and horizontally so as to engage the stack at the required position.
