RIDING TYPE WORK MACHINE

To provide a riding type work machine capable of appropriately turning according to conditions of a travel place in order to solve a problem that, in a case where a field is a wet field, driving of a drive wheel on a turning inner side is interrupted while turning and the wheel becomes idle turning wheel, a forward traveling driving force becomes insufficient, so that a case where turning is not achieved well (a case where a drive wheel on a turning outer side idles and does not travel forward in mud of a wet field and turning cannot be achieved) may occur in a riding type rice transplanter that turns in small radius without disturbing a travel place by interrupting driving of a drive wheel on a turning inner side by machine body turning operation with a steering handle for steering a steering wheel.SOLUTION: In a riding type work machine that interrupts driving of a drive wheel 6 on a turning inner side of the right and left drive wheels 6, 6 by machine body turning operation with a steering handle 16 for steering steering wheels 5, 5, a compulsive driving operation tool 60 for driving the drive wheel 6 is provided near the steering handle 16.SELECTED DRAWING: Figure 1 【課題】操向車輪を操舵するステアリングハンドルの機体旋回操作により、旋回内側の駆動車輪の駆動を切って、走行地を乱さずに小回り旋回する乗用型田植機がある。圃場が湿田の場合には、旋回時に旋回内側の駆動車輪の駆動が切断されて遊転輪となると、前進駆動力が足りなくてうまく旋回できないような事態（旋回外側の駆動車輪が湿田の泥土中で空転して前進せず旋回できないような事態）が発生することがある。そこで、走行地の条件に合わせて適切に旋回することができる乗用型作業機を提供する。【解決手段】操向車輪５，５を操舵するステアリングハンドル１６の機体旋回操作により、左右駆動車輪６，６の旋回内側の駆動車輪６の駆動を切る乗用型作業機において、ステアリングハンドル１６の近くに駆動車輪６を駆動する強制駆動操作具６０を設ける。【選択図】図１
