PROBLEM TO BE SOLVED: To provide a riding mower including a gas cylinder stably supported at a comparatively lower position of a machine body without interfering a range of view to lessen a possibility of the gas cylinder to contact other subject.SOLUTION: The riding mower includes: right and left driving rear wheels being independently drivable forward and backward, and a pair of right and left steerable front wheels 11. The riding mower includes a support device 3 capable of being mounted with a cylindrical gas cylinder 5 in a horizontal position on an external side of a rollover protection frame 2. The support device 3 is disposed such that the mounted gas cylinder 5 is positioned along front and rear of the rollover protection frame 2 and is mounted in a tilted state in which the central axis of the cylindrical gas cylinder 5 is closer to a central side in a lateral direction of a vehicle body toward a rear side from a plan view.COPYRIGHT: (C)2012,JPO&INPIT【課題】ガスボンベを機体の比較的低い位置で安定良く、かつ視界を妨げずに支持し、ガスボンベが他物と接触する可能性を少なくする。【解決手段】左右各別に正逆転駆動可能な走行用の後輪12と、操向操作可能な左右一対の前輪11とを備えた乗用型草刈り機において、転倒保護フレーム2の横外側に円筒状のガスボンベ5を横倒し姿勢で搭載可能な支持装置3を設け、この支持装置3を、搭載されたガスボンベ5が転倒保護フレーム2の前後にわたって位置し、かつ円筒状のガスボンベ5の中心軸線が平面視で後方側ほど機体左右方向での中心側に近付く傾斜姿勢で搭載されるように構成した。【選択図】図2
