is installed. Details of the Land Leveling Carrier 35 can be found in Part 4.
Shown below. The ground leveling carrier 35 is formed by a fixed front wall 36, left and right walls 38, 39, and a rear wall 40, which are detachable from a bottom wall 37. A small inlet 41 is opened near the front side of the bottom wall 37, and a small plow 42 is attached to the inlet 41. The tip of the plow 42 protrudes downward like a plane blade, and is used for leveling the ground. When the carrier 35 moves forward, it scrapes the ground surface, and the excavation is carried out by the leveling carrier 35.
Let it flow inside. When the inlet 41 is not in use, a lid 43 is attached to cover it. When the lid 43 is folded down, it covers the inflow port 41.
Reference numeral 44 denotes engagement tools attached to the left and right sides of the bottom wall 37, and hooks 45 attached to the lower ends of both the left and right walls 38, 39 engage with these.
