摘要

PROBLEM TO BE SOLVED: To provide a combined tilling apparatus with which a disk harrow of single row is arranged while restricting vertical motion behind a subsoiler, and digging, soil crushing and soil preparation are carried out by one stroke.;SOLUTION: This combined tilling apparatus has constitution that ruler wheels 4 and 5 are arranged at the right and left outside of the subsoiler 2 in the advance direction, and right and left disk harrow fixing arms 7 and 8 having front edge parts vertically rotatably connected to the right and left of the central part of a subsoiler frame 3 and back end parts projected to the back of the subsoiler 2 are installed and passed through an arm limit bracket 12 to restrict the vertical movement of the arms. A disk harrow fitting arm 14 is projected downwardly at the rear end parts of the arms 7 and 8 and the disk harrow 6 of single row having wider tilling width than the subsoiler 2 and an adjustable disk angle is arranged horizontally sideways at the lower part of a disc harrow fitting square frame 15 connected to the lower end part of the arm 14 perpendicularly and horizontally in the advance direction.;COPYRIGHT: (C)2006,JPO&NCIPI
