摘要： A drawbar having a boom with at least two pivotally connected sections which in a field position extend generally transversely of the direction in which the draw is drawn. Each section carries at least one first soil working device and at least one other second soil working device is trailed behind said first soil working device. The sections are pivotable in unison, about a horizontal axis transverse to the direction in which the drawbar is drawn, from said field position to a non-working position. In the non-working position the soil working devices are raised in order that the sections can be pivoted relatively to each other to a folded, transport position.

摘要： A combined depth-control and wing-lift hydraulic circuit is disclosed. The circuit is preferably used in combination with a farm implement having a tool bar. The tool bar is horizontally disposed relative to the ground, and is carried by the implement. The hydraulic circuit comprises means to raise and lower the tool bar relative to the ground, thereby to effect depth control. The tool bar includes pivotally connected wings. Each wing carries an associated wing wheel. The hydraulic circuit includes means for causing rotative movement of each wing about its associated tool bar pivot between a substantially horizontally-disposed position and a substantially vertically-disposed position, relative to the ground, and for further causing each wing to be selectively disposed at one of these positions, thereby to effect wing lift. Each wing wheel is coupled to, and is distally spaced from and located beneath, its associated wing structure when such wing is in the substantially horizontally-disposed position. Also, each wing wheel is outwardly spaced from its associated wing structure when the wing is in the substantially vertically-disposed position. The hydraulic circuit further includes means for causing each wing wheel to be drawn inwardly toward its associated wing structure when such wing is in the substantially vertically-disposed position, thereby to effect a special "wheel-tuck" feature of the present invention. The hydraulic circuit can additionally be used to control operation of a marker arm for forming marker furrows.
摘要翻译：公开了一种组合的深度控制和翼举升液压回路。该电路优选与具有工具条的农具组合使用。工具杆相对于地面水平设置，并由工具承载。液压回路包括相对于地面升高和降低工具杆的装置，从而实现深度控制。工具杆包括枢转连接的翼。每个翼都带有相关的翼轮。液压回路包括用于使每个机翼围绕其相关联的工具杆在基本上水平设置的位置和相对于地面的基本垂直布置的位置之间枢转的旋转运动的装置，并且用于进一步使每个机翼选择性地设置在一个的这些位置，从而实现机翼升力。当这种翼片处于基本上水平设置的位置时，每个翼轮联接到其相关联的机翼结构并且在其远侧间隔开并位于其相关联的翼结构下方。此外，当机翼处于基本垂直布置的位置时，每个翼轮与其相关翼结构向外间隔开。液压回路还包括当这种机翼处于基本上垂直设置的位置时使每个翼轮向内朝着相关联的机翼结构向内拉动的装置，从而实现本发明的特殊的“轮辋”特征。液压回路还可用于控制用于形成标记沟的标记臂的操作。

摘要： A ground working implement consisting of a hitch, a center section pivotally secured to the hitch for rotation about a transverse axis and a two part wing section pivotally secured to each side of the center section for rotation about a longitudinal axis, with the two parts joined on a diagonal axis, a transverse member across the central region of the hitch, a member pivotally secured between the wing section and the end of a bar such that the rotational movement of the wing parts about a diagonal axis, the rotation of the complete wing about a longitudinal axis, and the rotation of the hitch about a transverse axis, is permitted during ground cultivation, and when the wing section is raised vertically for transportation purposes, the hitch becomes rigid with the center section and movement about all axis is locked.

摘要： An improved chain lifter for foldable soil conditioner apparatus of the general type characterized by an elongated, foldable wing frame for soil conditioning members which is hingably mounted transversally on the rear of a main frame, is liftable from the ground by means of a lifting tower on the main frame, and is stabilized by reinforcing chains which extend rearwardly and outwardly from the main frame to the outer ends of the wing frame. Arm members which lift the chains have one end pivotally attached to the main frame whereas the other ends of the members are secured to the reinforcing chains intermediate to the ends thereof. Resilient biasing links interconnect the arm members with the upright lever of the lifting tower. Accordingly, the arms are pivoted upwardly and forwardly by means of the resilient biasing links when the wing frame is folded to a transport position, hence lifting the slackened reinforcing chains off the ground.
摘要翻译：一种用于可折叠土壤调节装置的改进的链条升降机，其特征在于一种用于土壤调节构件的细长的，可折叠的翼框架，其横向地安装在主框架的后部，可通过提升塔从地面上提升主框架，并且通过加强从主框架向后并向外延伸到机翼框架的外端的链条来稳定。提升链条的臂部件具有一端可枢转地附接到主框架，而这些构件的另一端固定到中间到其端部的加强链条。弹性偏置连杆将臂构件与升降塔的直立杆相互连接。因此，当翼架被折叠到运输位置时，臂通过弹性偏置连杆向上和向前枢转，从而将松弛的加强链提离地面。

摘要： An improved farm implement of the foldable, sectional tow type including a central section, including a wheeled cart and wing sections hingedly connected to the central section. Each of the wing sections is comprised of a plurality of hingedly connected frames to allow good ground coverage on abrupt terrain. The sections are further connected to the cart for movement between transport positions and cultivating positions and dampening means interconnect the various frames of the wing section and operable to preclude the same from oscillating relative to each other when in the transport position.
