Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain ploughs and their types, relay history, design and operation from agricultural sources, describe modern and traditional use, and distinguish ploughs from harrows, cultivators and no-till methods.

A farm implement for cutting, lifting and turning over soil to prepare a seedbed, bury weeds and residues and aerate the ground, historically drawn by oxen or horses in forms from the simple ard to the mouldboard plough with a curved share and mouldboard, and since the 20th century pulled by tractors or built as self-propelled motor ploughs, with variants such as reversible, chisel, disc and electric ploughs; the plough transformed agriculture and is a symbol of farming.

What it is for: Primary tillage of soil.

It can be explain types and design; relay history; describe use and alternatives; distinguish from other implements.

Distinguishing features

Cuts and turns soil

Share and mouldboard

Animal or engine traction

Symbol of agriculture

What it looks like

A frame with one or more curved blades that cut and turn furrows, drawn by animals or a tractor.

Physical character

earliest ards: about 4000 BCE period - evidence

mouldboard plough in Europe: medieval period - heavy plough

tractor plough furrows: up to 12 or more count - large models

How it is recognised

Soil-turning tillage implement

Mouldboard, ard, reversible, chisel, disc, motor and electric ploughs, animal-drawn ploughs

Harrows break clods; cultivators loosen without turning; no-till avoids ploughing

What the second pass must settle

  • Should the mouldboard plough and ard be separate primary entries?
  • How should agricultural sources be linked?
  • The registry entry has merged aliases naming variants and a historical company product; should they be split off?
