摘要： The present invention comprises a tractor tool that attaches to and detaches from a tractor frame easily. In one embodiment, as few as four bolts and two actuator control couplings are used to mount the inventive tool to a tractor. The inventive tractor attachment tool is capable of grasping and lifting a heavy or awkward object, moving it to a new location, and setting it down without the tractor operator leaving the tractor controls. The object may be simply or oddly shaped, and it may be moved to a location that requires it to be lifted over a barrier like a wall. Small trees, bushes, piles of vegetative matter, or fence posts can be pulled from the ground and moved to a rubble or debris bin for hauling. The tool is comprised of a metal frame having two jaw members that open and close in a scissor-like fashion. The jaw members are opened and closed by jaw actuators, controlled by the tractor operator sitting on the tractor. Using the inventive attachment, a tractor operator can grab an item lying in a field, lift it, rotate it, and deposit it in a bin that is located, for example, behind a wall without the operator having to leave the tractor cab.
摘要翻译：本发明包括一种拖拉机工具，其可以容易地附接到拖拉机框架上并与其分离。在一个实施例中，使用少至四个螺栓和两个致动器控制联接器将本发明的工具安装到拖拉机上。本发明的拖拉机附接工具能够抓住并抬起重或笨拙的物体，将其移动到新的位置，并且在没有拖拉机操作员离开拖拉机控制器的情况下进行设置。物体可以是简单的或奇怪的形状，并且其可以移动到需要将其提升到像墙壁这样的障碍物的位置。小型树木，灌木丛，植物物质堆砌或围栏柱可以从地面拉出并移动到瓦砾或垃圾箱进行拖运。该工具由金属框架构成，该金属框架具有以剪刀式打开和关闭的两个钳口构件。颚构件由夹爪致动器打开和关闭，由坐在拖拉机上的拖拉机操作器控制。使用本发明的附件，拖拉机操作者可以抓住位于田地中的物品，提起它，旋转它并将其放置在例如位于墙后面的仓中，而不需要操作者离开拖拉机驾驶室。
