摘要： Hydrostatic transmissions are useful for propelling a machine to do work and travel relative to the ground. In performing work functions and during travel it is desirable to adjust machine speed to aid in handling the machine. The subject hydrostatic transmission control system includes a infinitely adjustable creeper hand lever which can be moved to any desired position and be maintained in the selected position until moved by the operator. A spring biased inching pedal can be used in combination with the creeper lever to further adjust the machine speed. This arrangement of components provides a control system for the hydrostatic transmission which can be adjusted and maintained at a desired setting.

摘要： A braking apparatus includes a brake cylinder having a first opening and a second opening defined therein. The braking apparatus also includes a movable member located within the brake cylinder which has a channel defined therein. The braking apparatus further includes a brake chamber in fluid communication with the brake cylinder. The brake chamber has a brake member located therein. The movable member is moved to a position which allows fluid communication between the first and second opening through the channel thus creating a subsequent pressure drop in the system. The pressure drop causes a hydrostatic transmission in fluid communication with the brake apparatus to be neutralized by a responsive displacement of a pump and motor which reduces the travel speed of a vehicle. Additionally, the movement of the movable member causes a brake member to be forced against a moving object.

摘要： A retaining bracket for detachably connecting a pump to the power take off shaft of a tractor. The bracket provides a torque restraint which is non-rigid and centrally positioned in substantial alignment with the longitudinal axis of the pump shaft so that angular moments of force which would tend to bend the pump shaft are avoided or resisted. The bracket includes a channel-shaped member having a telescopic web and no precision alignment is required to operationally mount and connect the pump to the tractor. The bracket includes a slidable connection to the tractor drawbar so that no tools are required for operational mounting.

摘要： A rotomolded hydraulic oil tank includes an integral dividing baffle which strengthens the tank structure, and diverts and slows returning oil for better air removal and oil mixing. This occurs by positioning the dividing baffle so that the top of the baffle is just below the oil level in the tank so that returning oil must flow a greater distance around the baffle at a reduced velocity thereby increasing the time the oil is in the tank before exiting the tank through the tank suction. The lower velocity of the oil and the increased passage time allows air in the returning oil more time to float to the surface of the oil in the tank.
摘要翻译：滚塑液压油箱包括一个整体分隔挡板，加强了油箱结构，并转向并减缓了返回的油，以便更好地除气和油混合。这通过将分隔挡板定位成使得挡板的顶部刚好低于罐中的油位，使得返回的油必须以减小的速度在挡板周围流动更大的距离，从而增加油在罐中的时间通过油箱抽吸离开油箱。油的较低速度和增加的通过时间允许返回的油中的空气更多的时间漂浮到罐中的油的表面。
