PURPOSE:To provide a constant planting depth even if the height of a ridge changes, by pivoting and connecting a machine body of a planter through a horizontal shaft on either of the front and back of positions for supporting wheels of a running machine body and making the machine body of the planter in a given posture follow the ridge using a longitudinal guide mechanisms. CONSTITUTION:A travel transmission system of a driving mechanism (M) is formed from travel driving wheels 30 on the front end of a body 1 of a travel machine body (B) to the axle 10. A horizontal intermediate shaft 33 is driven through a transmission means 32 with a motor (M) of the machine body (C) of the planter and the horizontal intermediate shaft 33 is passed through the horizontal hollow shaft welded to the body 1. Support legs 48 and 64 of longitudinal guide mechanisms (K) and (L) moving in contact with ground on a ridge (N) are pivoted on the machine body (C) of the planter and a means for changing an angle included by the supporting legs 48 and 64 for the machine body (C) of the planter and regulating the height of the machine body (C) of the planter is provided.
