STUMP CUTTER

摘要

The present disclosure provides a device and method that enable the efficient reduction of stumps. In one embodiment the stump removal methods and devices according to the present disclosure allow the operator to have a clear view of the work area during operation, and the ability to move the reduction device through a wide range of motion during operation. In one embodiment, the material reduction tool pivots relative to the chassis in the vertical plane about multiple pivot points. In some embodiments the device includes a retractable auxiliary control panel located at the end of the device opposite the material reduction tool. The control panel enables the operator to direct the movement of the device from the end of the device and thereby enable the device to maneuver through narrow spaces.

主权项

1. A stump reducing machine comprising:
a chassis including a first end and a second end; an engine mounted to the chassis; a mounting member pivotally connected to the second end of the chassis, wherein the mounting member is configured to pivot about a substantially vertical axis; a material reduction linkage assembly mounted to the mounting member configured to enable a raising and lowering motion of a rotatable cutter wheel, the material reduction linkage assembly including: a first linkage pivotally mounted to the mounting member, the first linkage being configured to pivot about a substantially horizontal axis; a second linkage pivotally mounted to the mounting member, the second linkage being configured to pivot about a substantially horizontal axis; a third linkage pivotally mounted to the first linkage and the second linkage, the third linkage being configured to support the rotatable cutter wheel; andwherein the material reduction linkage, via the pivotal connection between the second end of the chassis and the mounting member, is configured to laterally sweep through a sweep range relative to the chassis thereby resulting in a sweeping motion of the material reduction tool for laterally engaging a stump.
