GRADING TOOLS FOR WORK MACHINES AND OPERATION THEREOF

摘要

One embodiment includes a grading tool structured for attachment to a work machine. The grading tool includes a frame, ground contacting wheels coupled with the frame, a comb coupled with the frame and extending from a first end of the frame, and a coupling member coupled with the frame and structured to be accessible from a second end of the frame. When the ground contacting wheels are in contact with the ground a depth of penetration of the comb into the ground surface is adjustable by changing the pitch of the grading tool.

主权项

1. An apparatus comprising:
a grading tool comprising a frame, ground contacting wheels coupled with the frame, a comb coupled with the frame and extending from a first end of the frame, and a coupling member coupled with the frame and located proximate a second end of the frame, the second end of the frame being opposite the first end of the frame; and a work machine comprising a tool mount coupled with the coupling member, a first actuator configured to apply force to selectably raise and lower the grading tool relative to the work machine in an active mode and to allow the grading tool to passively raise and lower relative to the work machine in response to external force in a float mode, and a second actuator configured to selectably change a pitch of the grading tool relative to the work machine in both the active mode and the float mode; wherein when the first actuator is configured in the float mode with the ground contacting wheels in contact with the ground a depth of penetration of the comb into the ground surface is adjustable by the second actuator changing the pitch of the grading tool relative to the work machine.
