摘要： A crop header has a cutter bar with generally horizontal flail disks driven about generally spaced upright axes. At least two of the disks are mounted outwardly of a discharge opening and the outermost disk carries an impeller and at least one additional impeller is mounted inwardly and rearwardly of the outer impeller to carry the crop inwardly. The impellers are formed of angularly spaced bars which are inclined inwardly to a center waist to form an “hour glass” shaped impeller. A transfer roller transfers the crop upwardly and rearwardly from the disks to the nip of a pair of conditioner rolls and is at least as large as the bottom roll and carries high ribs forwardly inclined for an aggressive action on the crop with its axis above the cuffing plane and its uppermost edge of the ribs at or above the axis of the bottom roll.

摘要： The center sickle overlap arrangement of a sickle type mower for a cutter bar that include a pair of sickles for reciprocating motion where each sickle is essentially half the length of the cutter bar for reduced forces and vibrations for high speed cutting. In the center, the sickle blades overlap at only guard and the blade of one sickle is inverted and co-operates with a top ledger surface of the associated guard so that both the blades are in proper shearing arrangement with the respective guard ledgers. Further the top ledger surface is adjustable to allow clearance adjustment to ensure tight clearance between all sickle cutting surfaces and guard ledgers. Further the arrangement ensures that all crop is cut between sickle sections and guard ledgers rather than between a pair of sections on the opposing sickles.

摘要： A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. The driven wheels are driven by hydraulic motors each having their own drive pump the output of which is controlled by a cam plate. The speed control is effected by a manually operable lever through a servo-cylinder which locates a speed control arm moving both cam plates to the set position. In a maximum speed position both cam plates are engaged against a stop. The steering is effected by moving the cam plates differentially to drive the wheels at different speeds. The piston rod of the servo-cylinder includes a spring relief so that the speed control arm can back off from the maximum position by moving the servo-cylinder body when steering in the maximum speed position.

摘要： A sprayer attachment is designed for mounting upon a swather tractor and includes a central frame with a tank which can be carried upon the front arms of the swather tractor. Two masts each carry a respective one of a pair of booms, each for extending outwardly to a respective side of the tractor for movement with the tractor in a spraying action. Each boom includes an inner section, an outer section and a tip portion. In the folding action the outer section and tip portion are folded about a horizontal axis so as to move to a position overlying the inner section. The folded boom is then pivoted about a vertical axis at the mast to lie along side the side of the tractor. The tip portion includes a parallel cable in advance of the tip portion for impacting an obstacle with the cable actuating release of the latch and accelerating the tip portion away from the obstacle to prevent impact with the obstacle. The tip portion is also moved to the retracted position during the folding action so that the maximum height of the outer section during folding is reduced to avoid contact with power lines and the like. The booms are inclined outwardly and rearwardly in the extended position to move the center of gravity rearwardly. The tank has two recessed sides to receive the arms of the swather tractor and a front which is inclined forwardly and downwardly to improve vision. Each boom is movable vertically along a vertical supporting mast independently for height adjustment. A hydraulic and electrical coupling allows the existing control lever of the swather tractor to control the boom movement.
摘要翻译：喷雾器附件设计用于安装在拖拉机上，并且包括具有罐的中央框架，该罐可以承载在swather拖拉机的前臂上。两个桅杆各自承载一对吊臂中的相应一个，每个吊杆均向外延伸到拖拉机的相应侧面，以便在拖拉机中以喷射动作运动。每个起重臂包括内部部分，外部部分和末端部分。在折叠动作中，外部部分和尖端部分围绕水平轴线折叠，以便移动到覆盖内部部分的位置。然后，折叠的吊臂在桅杆处围绕垂直轴线枢转，以便沿着拖拉机的侧面。尖端部分包括在尖端部分之前的平行电缆，用于通过电缆致动释放闩锁并使尖端部分远离障碍物来冲击障碍物，以防止与障碍物碰撞。在折叠动作期间，尖端部分也移动到缩回位置，使得折叠期间的外部部分的最大高度减小以避免与电力线等的接触。悬臂在延伸位置向外和向后倾斜以将重心向后移动。坦克具有两个凹陷的侧面，用于接收扫管拖拉机的臂部，前部倾斜向前和向下倾斜以改善视力。每个吊杆可以独立于垂直支撑杆垂直移动，用于高度调节。液压和电气联轴器允许拖拉机的现有控制杆控制吊杆运动。

摘要： A hydraulic drive apparatus for example for driving the header of a combine harvester includes a pump, at least one motor driven by the pump, a reservoir in which the hydraulic fluid is cooled and degasified and a hydraulic circuit connecting the elements. The pump is driven by a shaft of the combine which can be reversed for short periods of time for discharging blockages. The hydraulic circuit is arranged with check valves so that when operating in the normal forward condition it operates in open circuit arrangement including the reservoir. When operating in the reverse condition, the reservoir is bypassed and the fluid is directed in closed circuit condition from the pump through the motor and back to the pump. This allows the drive apparatus to accommodate the necessary reverse condition for short periods of time using a simple hydraulic circuitry rather than the conventional mechanical drive arrangements.

摘要： A control lever system for actuating the hydraulic pump of a hydrostatic transmission system of an agricultural vehicle includes a lever having a hand grip portion for actuation by the operator. The lever passes through an elongate slot in a console surface to control its movement. A lower end of the lever is connected to the pump. A friction resistance system is applied to the lever to generate a frictional force resisting the natural restoring force of the pump tending to move to the neutral postion. The friction resistance is applied only over the length of the slot relating to the forward movement of the pump so that there is no action at the neutral position or in reverse. The friction resistance includes a friction multiplier generated by a sub-lever portion pivotally mounted on the lever and biased by spring action when in contact with an abutment member to pinch a friction band so that the friction force generated by the band is greater than the spring action. The lever is shaped by an offset and by the inclination of the hand grip portion so that when pushed or pulled to move the lever from a set position the frictional resistance is reduced during movement and then automatically reapplied when the lever is released.
摘要翻译：用于致动农用车辆的静液压传动系统的液压泵的控制杆系统包括具有用于由操作者致动的手柄部分的杆。杠杆通过控制台表面的细长槽来控制其运动。杠杆的下端连接到泵。摩擦阻力系统施加到杠杆以产生抵抗泵的自然恢复力的摩擦力，倾向于移动到中性位置。摩擦阻力仅在与泵的向前运动相关的槽的长度上施加，使得在中性位置或反向不起作用。摩擦阻力包括由可枢转地安装在杠杆上的副杠杆部分产生的摩擦倍增器，并且当与抵靠构件接触以夹紧摩擦带时由弹簧作用而偏置，使得由带产生的摩擦力大于弹簧行动。杠杆通过偏移和手柄部分的倾斜度成形，使得当被推动或拉动以使杠杆从设定位置移动时，摩擦阻力在移动期间减小，然后当释放杆时自动重新应用。

摘要： A header frame for a combine includes a mounting frame which is attached to the front end of the feeder housing of the combine and a header frame. The header frame is mounted on the mounting frame by suitable linkage so that it can lift in a vertical direction and also can twist about an axis parallel to the forward direction of the combine to allow the header frame to follow ground contours. A flexible pan is connected between the header frame and the mounting frame to define a lower surface of the header immediately in front of the mouth of the feeder housing with the pan having a forward edge attached to the header frame and a rearward edge attached to the mounting frame with the movement therebetween being accommodated by flexing or sliding of one mounting of the pan. In one arrangement of the header, the conventional auger is replaced by two side drapers and a feed draper with the feed draper being mounted in a manner which allows limited vertical movement away from the pan.

摘要： A pull type swather or windrower which can be used either singly or in a duplex or tandem arrangement can be adjusted from a working position to a transport position by pivoting the hitch through 90.degree. and by unlocking the wheels so they turn through 90.degree. to move the swather at right angles to its working direction. The swather is mounted on two wheels inwardly of the ends of the swather and rearwardly of the drapers with the wheel remote from the hitch movable to a position forwardly of its working position so as to lie under the drapers and to balance the center of gravity so that the swather can be supported solely by the two wheels in the transport position. A rear or duplex swather can be attached to the front swather by a duplex hitch which provides steering movements of the rear swather in a direction opposite to the steering movements of the front swather so that the former properly tracks the latter in echelon relationship. The steering movements are obtained by a spring biassing the rear swather in one direction and a flexible linkage arrangement which controls the amount of movement of the rear swather. The intermediate hitch can be latched to the front swather to take up a transport position.

摘要： A draper header for harvesting crops includes a header frame with a middle frame section pivotally coupled between a pair of side wing sections. A cutter bar assembly extends across a front portion of the header frame and is flexible with the side wing sections for cutting the crops to be harvested. A pair of crop pick-up reels are rotatably supported by center and outer reel support arms for engaging the crops to be harvested. A sensing system is operatively coupled to the header frame for detecting when at least one of the side wing sections pivots downwardly relative to the middle frame section. When the sensing system detects that at least one of the side wing sections pivots downwardly past a predetermined pivot angle, a down-stop cylinder is actuated to raise the crop pick-up reels, thereby preventing contact of the crop pick-up reels with the cutter bar assembly.
