摘要： A tiller with a removable tine rotor is provided. The tiller comprises a cavity formed by a top deck and end plates. The end plates comprise rotating spindles rotatably attached to the end plates. A gearbox translates rotation from a tractor to one of the rotating spindles. A tine rotor extends between the spindles and rotates to till soil. The tine rotor is releasably connected to the spindles within the cavity, such that the tine rotor is removable from the tiller without disassembly of the end plates.

摘要： A post hole digger couples to the power take-off (PTO) shaft of a tractor and uses rotation from the PTO shaft to rotate an auger. A top support arm rotatably coupled to the top pin of the tractor's three point hitch supports the gearbox that translates rotation to the auger. A support frame extends upwardly from the right and left lift arms of the three point hitch and inwardly to support the top support arm from beneath. The support frame is shaped generally as an inverted “U,” with space created between the right and left lift arms to prevent interference with the rotating shaft that translates rotation from the PTO shaft to the gearbox. A shield coupled to the gearbox covers the moving parts of the joint between the rotating shaft and the gearbox and protects users during use of the auger.

摘要： A stump cutter comprising a cutting head that rotates about a generally vertical axis is provided. The cutting head comprises a plurality of cutting blades that are angled with respect to a backing plate of the cutting head. At least two of the plurality of cutting blades are further angled radially with respect to a center of the cutting head, such that the centermost edges of the cutting blades extend further into a stump than the outermost edges of the cutting blades. The stump cutter is powered solely by the PTO of a tractor.

摘要： A rotary mower has a lift frame comprising swiveling linkages that allow rotation of the deck with respect to a three point hitch. The lift frame further has a pair of angled legs rotatably affixed to the lift frame, each angled leg having an upper end and a lower end, the lower ends rotatably affixed to pivot brace brackets rigidly affixed to the deck. Each angled leg of the lift frame is rotatably affixed to one or more pivot bars near the upper end of the angled leg. Each pivot bar extends upwardly between the angled leg and an upper end of the lift frame. A shield covers the pivot bars to protect the users.

摘要： An articulated arm and cutter attachment for mounting on a tractor has a pair of elongated vertical booms pivotally connected to one another at their top ends. The lower end of one of the booms is pivotally connected to a beam extending laterally from underneath the tractor chassis. The other boom has a telescoping lower end on which is mounted a foot which supports a rotary cutter. An upper portion of the beam connected to the tractor is inclined outwardly, and an upper portion of the other beam is inclined inwardly to allow the arm to reach out a substantial distance and extend over obstacles such as fences. Pivoting mechanisms in the foot allow tilting of the supported cutter over a wide range of angular positions. Hydraulic cylinders are provided for carrying out movement of the arm, along with hydraulic fluid lines and controls. Yieldable mounting of the foot provides for breaking away of the cutter upon striking an obstacle.
摘要翻译： 用于安装在拖拉机上的铰接臂和切割器附件具有一对在它们的顶端彼此枢转地连接的细长的垂直臂。 一个悬臂的下端枢转地连接到从牵引车底盘下方横向延伸的梁。 另一个起重臂具有伸缩的下端，其上安装有支撑旋转切割器的脚。 连接到拖拉机的梁的上部向外倾斜，另一个梁的上部向内倾斜，以允许臂伸出相当大的距离，并延伸到诸如栅栏的障碍物上。 脚中的转动机构允许支撑的刀具在宽范围的角位置上倾斜。 提供液压缸用于执行臂的运动，以及液压流体管线和控制器。 脚的可屈曲的安装提供了在撞击障碍物时切割刀具。

摘要： A support stand for an implement such as farming equipment is provided. During use of the implement when the implement is connected to a tractor, the support stand is in a stowed position adjacent to a surface of the implement. When the implement is disconnected from the tractor, the support stand is rotatable outwards from the surface of the implement and downwards towards the ground and rests against the ground to maintain the implement in a generally upright position.
