摘要： An automatic tensioner to be used with a drive train of a self-propelled mower for drivingly connecting a ground wheel to the mower transmission, wherein the tensioner includes tensioning mechanism, which may be constructed as a spring biased idler arm having an idler member rotatably mounted thereon, to apply a tensioning force against the flexible element of the drive. The tensioner further includes an anti-slackening assembly having an elongated takeup rod being pivotally coupled with the idler arm at one end thereof so that the takeup rod moves generally with the idler arm, as the arm moves in a tensioning direction and opposed slackening direction. The anti-slackening assembly also includes a swingable control tab having an aperture receiving the other end of the takeup rod. The tensioner is constructed so that the takeup rod engages the aperture of the control tab to swing the control tab to a disposition in which the takeup rod is generally aligned with the aperture permitting relative movement therebetween as the idler arm and takeup rod move in the tensioning direction, and to alternatively swing the control tab to a locking position in which the takeup rod is canted within the aperture to prevent the idler arm and takeup rod from moving in the slackening direction.
摘要翻译：一种自动张紧器，与自行式割草机的传动系一起使用，用于驱动地将轮胎连接到割草机传动装置上，其中张紧器包括张紧机构，该张紧机构可被构造为具有可旋转地安装的惰轮构件在其上施加张紧力抵抗驱动器的柔性元件。张紧器还包括防松松组件，该防松松组件具有细长的卷取杆，其在其一端处与惰轮枢转地联接，使得当臂沿张紧方向和相对的松弛方向移动时，卷绕杆大体上与惰轮一起移动。抗松弛组件还包括一个可摆动的控制翼片，其具有容纳卷绕杆的另一端的孔。张紧器被构造成使得卷绕杆接合控制翼片的孔，以将控制翼片摆动到摆放位置，其中卷绕杆通常与孔对准，允许相对运动，因为惰轮臂和卷取杆在张紧中移动并且可选地将控制翼片摆动到锁定位置，在锁定位置中，卷绕杆在孔内倾斜，以防止惰轮臂和卷取杆在松弛方向上移动。

摘要： A self-propelled, walk-behind traction vehicle includes a power source, a pair of drive wheels and an improved operator-manipulated drive control mechanism for selectively coupling the drive wheels to the power source in a manner that allows the operator to control propulsion and steering of the vehicles. The drive control mechanism includes a friction drive unit having a pair of reversible, variable speed transmissions associated with respective ones of the drive wheels for selectively coupling the drive wheels to the power source. The control mechanism further includes a pair of independently swingable control handles configured to be gripped by the operator and operably coupled to respective ones of the transmissions so that the speed and direction of rotation of each of the drive wheels is controlled by swinging a respective one of the handles.
