摘要： A mower is provided which includes a pair of link mechanisms for mounting a cutter unit on the side of a mower body in suspended form. Each link mechanism includes a pair of lifting links. The paired lifting links are pivotably connected to the side of the mower body at opposing end portions. The other end portions of the paired lifting links are connected together so that the paired lifting links can be rotated upward and downward about the respective pivot points. The cutter unit is supported by respective intermediate portions of the lifting links in suspended form, and lifted by rotating the lifting links of the paired link mechanisms upward and downward in a linked relation.

摘要： A stepless speed change mechanism in a belt transmission device comprising a first belt passed through a groove in a drive pulley and a first groove in an intermediate pulley, and a second belt passed through a second groove in the intermediate pulley and a groove in a driven pulley for transmitting rotation from the drive pulley to the driven pulley via the intermediate pulley. The first groove and the second groove of the intermediate pulley have an axial width gradually decreasing radially inwardly of the pulley. A partition provided between and defining the first and second grooves of the intermediate pulley is movable axially of the pulley to thereby vary the pitch diameter of each of the first and second grooves and steplessly change the speed of rotation to be transmitted from the drive pulley to the driven pulley. The state of contact of the first belt with the first groove portion is adjusted to be different from the state of contact of the second belt with the second groove portion so that when the partition moves axially for the speed change, the axial component of the pushing force exerted on the partition by one of the first and second belts differs in magnitude from the axial component of the reaction force exerted on the partition by the other belt.

摘要： A belt transmission in which a transmission belt is reeved around each of a reversible drive pulley and a driven pulley and which includes a pair of tension pulleys provided respectively on the taut side and the slack side of the belt in contact therewith. The two tension pulleys are biased by an elastic body to tension the belt. A first link is connected to one of the tension pulleys, and a second link to the other tension pulley. The two links are each pivotally movable in a direction for the corresponding tension pulley to tension the belt and in a direction for the tension pulley to relieve the tension. The two links are pivotally movable about a common axis. When the direction of rotation of the drive pulley is changed, reversing the taut side and the slack side of the belt, the tension imparted to the belt by the tension pulleys is automatically adjusted properly by the pivotal movement of the two links.

摘要翻译： 一种传动带，其中传动带围绕可逆驱动滑轮和从动皮带轮的每一个旋转，并且包括分别设置在与其接触的皮带的拉紧侧和松弛侧的一对张力皮带轮。 两个张力滑轮由弹性体偏压以张紧皮带。 第一连杆连接到一个张力滑轮，以及第二连杆连接到另一张力滑轮。 两个连杆都可以在相应的张力滑轮的方向上枢轴运动，以张紧皮带，并在张力滑轮的方向上缓解张力。 两个连杆可绕公共轴线枢转运动。 当驱动皮带轮的旋转方向改变时，使皮带的拉紧侧和松弛侧反转，由张力滑轮赋予皮带的张力通过两个连杆的枢转运动被适当地自动调节。
