A high-density type cultivation equipment has an improved mechanism to transfer cultivation beds from one main rail track to the adjacent main rail track, in which transfer rail tracks 1 that connect ends of main rail tracks 3 consist of two pairs of parallel feed rollers 1' that are rotated in a common direction at an identical velocity, are arranged with a track gauge related to the distance between wheels which cross said main rail tracks with an angle declined from a right angle by a feed angle alpha at substantially the same height with said main rail tracks. The wheels 15 of cultivation beds B have the axles 15a thereof fixed in direction to be perpendicular to the central axes of the main rails. As means to drive said cultivation beds B along the main rail tracks 3 in a cyclic path, hook means 4 that detachably engage with structural members 10 of said cultivation beds B are provided to be driven in the direction parallel to the main rail tracks 3. The cultivation beds that have reached the end of one of the main rail tracks are transferred to the adjacent main rail track automatically, thereby enhancing effectiveness of mechanized concentrated agriculture.
