摘要： An improved double disk blade opener assembly and disk blade therefor are provided for a grain drill or the like. A pair of bearings are supported on opposite sides of a seed boot casting or arm structure mounted on the implement. Each bearing supports a threaded shaft which extends outwardly therefrom to a blade-receiving end. A pair of generally flat disk blades each fabricated from a single piece of sheet metal and having opposed outwardly cupped central portions to accommodate the bearings are secured on and rotate with the shafts. Mounting the bearings in the boot rather than in bearing caps on the blade decreases the overall width of the opener and increases trash flow between adjacent openers. Socket screws which previously were used to secure the blade assembly to the boot, which required tapping of the boot and which frequently worked loose therefrom are eliminated. The specially shaped disk blades retain the desired furrow cutting characteristics of conventional flat disk blades.

摘要： For an implement, a caster wheel assembly including a tubular member connected to reciprocate as the caster wheel swivels. An adjustable brake assembly resists movement of the tubular member to eliminate caster wheel wobble as the implement is transported. A plurality of caster wheel assemblies permit the implement to crab between the towing vehicle and a trailing implement. The brake assemblies provide convenient locking and control of selective wheels for the desired swivel action in numerous operating situations.

摘要： An improved assembly is provided for mounting a disk blade to the drawbar or standard of a furrow opener on a grain drill, planter or similar implement. A bearing support is attached to the drawbar. A bearing includes an outer race held by the bearing support, an inner race extending axially beyond the support and a single disk blade receiving bolt depending from the inner race. A disk blade is secured on the bolt between the inner race and a securing nut threaded on the end of the bolt so that the bolt, disk blade and inner race rotate together about the axis of the bolt. Since the bearing is not riveted or otherwise supported on the disk blade, the blade can be removed from the bolt and replaced easily and quickly without having to replace the bearing. The bearing case normally riveted to the disk blade is eliminated increasing the clearance between blades for better flow of dirt and trash.

摘要翻译： 提供了一种改进的组件，用于将圆盘刀片安装到谷物钻机，花盆或类似工具上的牵引杆或开沟器的标准上。 牵引杆附有轴承座。 轴承包括由轴承支撑件保持的外圈，轴向延伸超过支撑件的内圈和从内圈悬挂的单个盘片接收螺栓。 一个盘片固定在螺栓之间的螺栓上，内圈和螺母螺栓固定在螺栓的端部，使得螺栓，盘片和内圈围绕螺栓的轴线一起旋转。 由于轴承没有被铆接或以其他方式支撑在盘片上，所以可以将刀片从螺栓上取下并且容易且快速地更换，而不必更换轴承。 通常铆接到盘片的轴承箱被消除，增加了叶片之间的间隙，以更好地流动污垢和垃圾。

摘要： An agricultural implement having a transverse main frame and transversely extending tool-carrying outer sections rearwardly foldable for transport. The main frame supports a pair of slide members which shift laterally thereon and to which the outer sections are pivotally connected. A hydraulically powered cylinder shifts the slide members transversely to separate the outer sections and provide clearance for tools carried thereon and smaller hydraulic cylinders swing each outer section about the pivotal connection and between their transverse and fore-and-aft positions.
