PROBLEM TO BE SOLVED: To provide a tea field-managing machine with which expansion amounts of right and left frames are readily made coincident and the central position of a tea field-managing apparatus is readily made coincident with that of the body of the machine body without significantly changing the structure of the machine body.;SOLUTION: The inter truck expansion type tea field-managing machine is equipped with an inter truck expansion apparatus 12B furnished with fulcrum parts 120 and 130 attached to connecting frames 13C, 14C and 15C so as to be reciprocated in the longitudinal direction of the machine body 11 and with a pair of a right and a left connecting members 121, 122, 131 and 132 which are swingably placed in a line to the fulcrum parts and swingably connected to right and left frames 13A, 13B, 14A, 14B, 15A and 15B. The one pair of the right and left connecting members widen and narrow the right and left frames synchronously according to reciprocating actions of the fulcrum parts. The tea field-managing apparatus is attached to the connecting frames.;COPYRIGHT: (C)2006,JPO&NCIPI
