Abstract
A bedding plow suited for forestry planting operations includes a plow frame that is attached to a tractor or other tow vehicle. The frame holds a pair of trailing disk assemblies that are arranged along opposite longitudinal sides of the bed being plowed. A center-cut disk assembly is mounted pivotably to the frame between and forwardly of the trailing disk assemblies. A resilient biasing assembly such as a hydraulic or pneumatic relief mechanism interconnects an arm of the center-cut disk assembly and the frame. The resilient biasing device urges the center-cut disk assembly to engage the ground under normal circumstances and permits the disk assembly to retract upwardly and ride over obstructions that are encountered while the plow cultivates the bed.
Claims9
A bedding plow apparatus that is operably attachable to a tow vehicle for plowing a forestry bed, said apparatus comprising:
- a frame attachable to and adapted for being pulled by the two vehicle along the forestry bed;
- a pair of trailing disk assemblies depending from said frame and disposed generally along respective longitudinal sides of the bed, each said trailing disk assembly including a trailing arm that is pivotably connected proximate a forward end thereof to said frame and at least one trailing disk that is mounted to said trailing arm proximate a distal end thereof such that said trailing disk is pulled through the bed as said frame is pulled by the tow vehicle;
- a center-cut disk assembly depending from said frame laterally between said trailing disk assemblies, said center-cut disk assembly including a center-cut arm pivotably attached proximate a forward end thereof to said frame and at least one center-cut disk mounted to said center-cut arm proximate an opposite distal end thereof, each said center-cut disk being cuttably engagable with a longitudinal center axis of the forestry bed;
- and
- a relief mechanism resiliently interconnecting an intermediate portion of said center-cut arm with said frame and urging said center-cut disk assembly to extend downwardly and engage the bed so that each said center-cut disk precuts the longitudinal center axis of the bed as the frame is pulled by the tow vehicle along the forestry bed;
- said relief mechanism further permitting said center-cut disk assembly to retract upwardly and traverse obstructions in the bed.
