PROBLEM TO BE SOLVED: To provide a rear mower capable of achieving a sufficient lifting or lowering level when once holding up a rear mower by lifting the mower from a lawn-mowing state of a lowered state of the rear mower to move the rear mower.SOLUTION: The lifting or lowering mechanism of the riding rear mower is constituted as follows. A right and left turnably and pivotally supporting cylinder 36 is fixed to the tip of a lift arm 9 to be lifted, lowered and turned by a lifting and lowering hydraulic cylinder 4, and a right and left turning shaft 35 is fitted in the right and left turnably and pivotally supporting cylinder 36. A horizontally turnably and pivotally supporting cylinder 37 is fixed to the front terminal part of the right and left turning shaft 35, and a horizontally turnably and pivotally supporting pin 25 is fitted in the horizontally turnably and pivotally supporting cylinder 37. The front part of a front mower unit 1 is pivotally supported by the horizontally turnably and pivotally supporting pin 25 so as to be freely horizontally turnable, and the front mower unit 1 is supported so as to be turnable in the front and rear direction. The rear part of the front mower unit 1 is hung down and supported by a swing-preventing chain 3 supported by the lift arm 9. The swing-preventing chain 3 enables the upper and lower position based on the lift arm 9 to be changed with the lifting, lowering and turning of the lift arm 9.COPYRIGHT: (C)2012,JPO&INPIT【課題】リールモアを下降した状態で、芝生の刈取りを行っている状態から、リールモアの移動の為に、一旦、リールモアを上昇して持ち上げる場合に、十分な昇降レベルを得ることが出来るリールモアを提供する。【解決手段】昇降油圧シリンダ4により昇降回動するリフトアーム9の先端に左右回動枢支筒36を固設し、左右回動枢支筒36に、左右回動軸35を嵌装し、左右回動軸35の前端部に、水平回動枢支筒37を固定し、水平回動枢支筒37内に、水平回動枢支ピン25を嵌装し、水平回動枢支ピン25によりフロントモアユニット1の前部を水平回動可能に枢支するとともに、フロントモアユニット1を前後方向に回動可能に支持し、リフトアーム9に支持した揺動阻止チェーン3によりフロントモアユニット1の後部を吊り下げ支持し、揺動阻止チェーン3は、リフトアーム9の昇降回動と共に、リフトアーム9に対する上下位置を変更可能とした。【選択図】図4
