PROBLEM TO BE SOLVED: To provide an epoch-making riding furrow opener which can achieve a stable travel on a field with a driving device and can be ridden not only on the field but also on a road such as a pavement.SOLUTION: This riding furrow opener has a riding portion 3 provided with a front wheel 1 to be steered and a rear wheel 2 used as a driving wheel. At least the rear wheel 2 is configured of a plurality of wheels of a right rear wheel 2R and a left rear wheel 2L, which are connected to a rotation driving shaft rotated with the driving device 8 to drive the wheels, and a driving/free-switching mechanism 11 for switching between a driving-connection state, for transmitting the rotation of the rotation driving shaft, and a free connection state, for not transmitting the rotation to be freely rotated, is disposed to a connection portion 10 for connecting the rotation driving shaft to the right rear wheel 2R or the left rear wheel 2L.COPYRIGHT: (C)2011,JPO&INPIT【課題】駆動装置による圃場での安定走行を実現すると共に、圃場だけでなく舗装路のような道路でも乗用が可能となる画期的な乗用溝切り機を提供すること。【解決手段】操舵する前輪1と、駆動輪となる後輪2とを乗用部3に設け、少なくとも後輪2を右後輪2Rと左後輪2Lとを有する複数輪に構成すると共に、この右後輪2Rと左後輪2Lとを、駆動装置8により回転駆動される回転駆動軸と連結して駆動するように構成し、この回転駆動軸と前記右後輪2R若しくは左後輪2Lとを連結する連結部10に、この回転駆動軸の回転を伝達する駆動連結状態と回転が伝達されないで回転自在となるフリー連結状態とに切り替える駆動・フリー切り替え機構11を設ける。【選択図】図2
