摘要： A compact utility loader incorporating a boom of adjustable length. The boom may include one or more lift arm assemblies, with each lift arm assembly including a first lift arm that telescopically receives a second lift arm. Each lift arm assembly also includes a telescoping actuator adapted to telescopically extend and retract its second lift arm relative to its first lift arm. A load-sensing system may be provided and adapted to limit lift arm assembly extension based at least in part upon a tool load applied at a tool supported by the boom.

Both the first portion and diagonal portion each have a top surface, a bottom surface opposite said top surface, a plurality of side surfaces, and first and second longitudinal axes, respectively, that substantially bisect each portion. The first portion and diagonal portion are oriented so that the first longitudinal axis and the second longitudinal axis are diagonal to one another. The desktop also includes a return portion having a top surface, a bottom surface opposite the top surface, and a plurality of side surfaces. The return portion is joined with the first portion and has a third longitudinal axis that substantially bisects the top surface of the return portion. The third longitudinal axis is substantially perpendicular to the first longitudinal axis.

摘要： A slow in turn system for a vehicle comprises an accelerator linkage that is linked to the input lever of a variable speed transmission. The accelerator linkage includes first and second link arms that couple a foot pedal to a rotatable cam plate. The link arm that connects to the cam plate is coupled thereto by a slider so that the connection point of that link arm may be moved towards and away from the pivot axis of the cam plate. The slider is moved away from the pivot axis of the cam plate during turns of the vehicle to reversely rotate the cam plate, and hence retard the input lever of the speed changing system, to thereby automatically slow the vehicle. This movement of the slider is accomplished by a connecting linkage extending to the steering system of the vehicle. In addition, the vehicle includes a cruise control system that can be set to obtain a particular forward speed but which allows the operator to temporarily speed up without subsequently having to reset the cruise control system. The slow in turn system works without affecting the position of the accelerator foot pedal and without requiring the cruise control system to be disengaged.
摘要翻译：用于车辆的缓慢转向系统包括与变速传动装置的输入杆连接的加速器联动装置。加速器联动装置包括将脚踏板联接到可旋转凸轮板的第一和第二连杆臂。连接到凸轮板的连接臂通过滑块与其连接，使得连杆臂的连接点可朝向和远离凸轮板的枢转轴线移动。在车辆的转弯期间，滑块从凸轮板的枢转轴线移开，以使凸轮板反向旋转，因此延迟变速系统的输入杆，从而自动地减慢车辆的速度。滑块的这种移动通过延伸到车辆的转向系统的连接联动来实现。另外，车辆包括巡航控制系统，该巡航控制系统可以被设置为获得特定的前进速度，但是允许操作者临时加速而不必重新设定巡航控制系统。缓慢的系统工作而不影响加速踏板的位置，而不需要巡航控制系统的分离。

摘要： A sprocket is disclosed for driving a chain with a plurality of chain rollers. The sprocket may be used to drive a material removal chain of a trencher. The sprocket has various cut-aways or reliefs on each face thereof to more effectively clear particulate debris from beneath chain rollers during cutting or digging operations. The sprocket also has asymmetrical teeth designed to help minimize changes in pitch diameter due to debris entrained beneath chain rollers. Reducing changes in pitch diameter greatly reduces premature wear of the sprocket and its chain. Reducing changes in pitch diameter also greatly reduces the tendency for the chain to bind.

摘要： A cruise control system for a vehicle comprises an accelerator linkage that is linked to the input lever of a variable speed transmission. The accelerator linkage is biased to neutral, but can be moved against the bias by an operator who pushes down on an accelerator. A cruise control link which is separate from the accelerator linkage has one end coupled to the accelerator linkage by a pin and slot connection. The cruise control link can be locked in a fixed position by an electromagnet that can be selectively energized by the operator. A spring normally keeps the pin on the cruise control link in engagement with a forward end of the slot carried on the accelerator linkage to prevent the accelerator linkage from returning to neutral when the cruise control link is locked in place by the electromagnet. However, the operator can temporarily increase the vehicle speed since additional forward movement of the accelerator linkage is permitted by the length of the slot. This additional forward movement of the accelerator linkage does not lose or destroy the current fixed setting of the cruise control link.
摘要翻译：用于车辆的巡航控制系统包括连接到变速传动装置的输入杆的加速器联动装置。加速器连杆被偏压到中立，但是可以通过下推加速器的操作者抵抗偏压来移动。与加速器联动分离的巡航控制连杆具有通过销和槽连接件联接到加速器联动装置的一端。巡航控制链路可以通过可由操作者选择性地供电的电磁体锁定在固定位置。弹簧通常将引导件保持在巡航控制链路上，与加速器联动装置上承载的槽的前端接合，以防止当巡航控制链路被电磁铁锁定就位时加速器联动返回中立。然而，由于加速器连杆的额外向前运动允许槽的长度，所以操作者可以临时增加车辆速度。加速器联动装置的这种额外的向前运动不会损失或破坏巡航控制连杆的当前固定设置。

摘要： A two stage snowthrower includes snow removal components comprising a transversely extending auger housed within an auger housing. A generally cylindrical impeller housing is joined to a rear wall of the auger housing. A rotatable impeller within the impeller housing rotates within a circular cross-section of the impeller housing to throw snow upwardly through a snow discharge pipe. The snow discharge pipe is offset to one side of the impeller housing such that a first side wall of the snow discharge pipe is longer than a second side wall of the snow discharge pipe. The first side wall of the snow discharge pipe is joined to the circular cross-section of the impeller housing along a first edge where snow is thrown upwardly by the impeller. The circular cross-section of the impeller housing resumes at a second edge which is displaced laterally and below a lower edge of the second side wall.
