PROBLEM TO BE SOLVED: To provide a riding rice planting machine or a riding direct seeding machine in which the lowering limit of rear wheels in a suspension mechanism is set as predetermined, and the low limit setting mechanism facilitating assembly and adjustment is included.SOLUTION: A regulating lever supporting part 60 is provided in a machine body side spring receiving part 52. A lower end side is supported to a wheel side spring receiving part 51 and an upper end side is supported to the regulating lever supporting part 60 in a set range in a vertically slidable manner, and also a lowering regulating lever 55 for setting the lowering limit of wheel side spring receiving part 51 is included. The regulating lever supporting part 60 includes: a frame body part 61 extended from the machine body side spring receiving part 52 while being formed in a groove type opened horizontally; a support 62 supported in the inside of the frame body part 61, and supporting the lowering regulating lever 55 in a set range in a vertically slidable manner; and a reinforcing plate part 65 connected to the groove open end of the frame body part 61, and supporting the end 62b of the groove open end side in the support 62.SELECTED DRAWING: Figure 6
【課題】サスペンション機構における後車輪の下降限界を所定どおり設定させ、かつ、組付けや調整をし易い下限設定機構を備える乗用型田植機又は乗用型直播機を提供する。【解決手段】機体側バネ受け部52に規制杆支持部60が設けられている。車輪側バネ受け部51に下端側が支持され、上端側が規制杆支持部60に設定範囲で上下スライド可能に支持され、車輪側バネ受け部51の下降限界を設定する下降規制杆55を備えている。規制杆支持部60は、水平向きに開放する溝型に形成された状態で機体側バネ受け部52から延出された枠体部61と、枠体部61の内部に支持され、下降規制杆55を設定範囲で上下スライド可能に支持する支持体62と、枠体部61の溝開放端部に連結され、支持体62における溝開放端部側の端部62bを支持する補強板部65とを備えている。【選択図】図6
