The hydraulic cylinder is installed in the horizontal direction of the street and the auxiliary address is installed on both sides so that the oil pressure of the hydraulic cylinder is taken in and out so that the auxiliary address can be spread widely so that the flat work can be performed on a large area of the rice field at once. Which can be easily connected to a telescopic table.;Conventional addressing has a disadvantage that it must be attached at the time of work and removed at the time of not working.;Therefore, in the present invention, the address body 2 and the auxiliary addresses 3 and 3 'are connected to the oil pressures 5 and 5' of the hydraulic cylinder 4 on both sides, (3b), and a soil discharging hole (2 ') is installed in an address body (2);The steel wires 21 and 21 'are connected to both ends of the shaft 8 provided on the upper support 7 of the address body 2 and the fixing pins 18 and 18' And the fixing bolts 20 are fixed to the upper ends of the fixing screws 13 and 13 ' The steel wires 21 and 21 'can be lifted up to the shaft 8 to perform other operations, so that it is not necessary to perform troublesome installation and separation operations of the expansion and contraction address.
