The pith

The invention is a self-resetting stubble stomper using a hinge assembly, torsion spring, and disengageable spring pin to protect harvesting headers from damage while maintaining operational position.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The device mounts to the front of a combine or similar harvester. A stomper shoe rides along the ground and flattens leftover crop stalks. If it hits a rock or hard obstacle, a spring pin releases, letting the whole assembly swing backward and upward to clear the obstacle. Once past the obstacle, the torsion spring and hinge geometry pull the shoe back into its original working angle without any manual reset. All motion stays within a controlled range so the machine can keep harvesting without stopping.

Core claim

A stubble stomper comprising a stomper mounting bracket, hinge assembly rotatable between default and breakaway positions, stomper shoe pivotally attached by a bushing, torsion spring biasing the shoe, and spring pin for selective engagement that prevents rotation in the default position and allows it in the breakaway position.

Load-bearing premise

The combination of hinge, bushing, torsion spring, and spring pin will reliably disengage on impact, clear obstacles, and return to the default position under field conditions without jamming or excessive wear.

1 . A stubble stomper comprising: a stomper mounting bracket adapted for mounting the stubble stomper to a crop harvesting header on an agricultural machine; a hinge assembly rotatably attached to the stomper mounting bracket and rotatable between a default position and a breakaway position; a stomper shoe pivotally attached to the hinge assembly by a bushing for engaging crop stubble as the agricultural machine travels across a field; a torsion spring surrounding the bushing that is coupled between the hinge assembly and the stomper shoe biasing the stomper shoe in a first rotational direction relative to the hinge assembly to position the stomper shoe for engaging the crop stubble; and a spring pin attached to the stomper mounting bracket for selective engagement with the hinge assembly, wherein when the spring pin is engaged with the hinge assembly, the hinge assembly is in the default position preventing rotation in the first rotational direction and a second rotational direction and when the spring pin is disengaged from the hinge assembly, the hinge assembly is in the breakaway position allowing rotation in the first and second rotational directions.

Editorial analysis

A structured set of objections, weighed in public.

Desk editor's note, referee report, simulated authors' rebuttal, and a circularity audit. Tearing a paper down is the easy half of reading it; the pith above is the substance, this is the friction.
