ABSTRACT:
An improved land vehicle for constructing rice levees comprises a unitary, ground contacting roller-wheel assembly surrounded by a frame member. The shape and size of the roller permits the construction of rice levees having the desired shape and dimensions. The roller is hollow so that it may be filled with materials as desired to vary its weight and thereby adapt it for varying rice field conditions. Tires mounted on the roller-wheel assembly function to aid in levee construction and to allow the vehicle to be transported without the use of special equipment.
