PROBLEM TO BE SOLVED: To provide an agricultural material supply device configured such that the reciprocation operation of a drive unit is efficiently transmitted to both of first and second one-way clutches, and the drive shaft of a feeding unit is rotationally driven.SOLUTION: First and second linkage members 51, 52 are connected across a single drive unit 46 reciprocated in a predetermined range of A2 and arms 41a, 42a of first and second one-way clutches. By the forward operation of the drive unit 46, the first one-way clutch is rotationally driven in a predetermined direction B1, the second one-way clutch is rotationally driven in the direction opposite to the predetermined direction B1, and a drive shaft 37 is rotationally driven in the predetermined direction B1 by the first one-way clutch. By the backward operation of the drive unit 46, the first one-way clutch is rotationally driven in the direction opposite to the predetermined direction B1, the second one-way clutch is rotationally driven in the predetermined direction B1, and the drive shaft 37 is rotationally driven in the predetermined direction B1 by the second one-way clutch. |
