A jointer or skimmer which skims stubble and grass from the surface of the soil and throws them into the bottom of the furrow where they are completely covered. The jointer helps also to pulverize the soil.
A truck or wheel, attached under the end of the beam. This truck makes the plow run steadier. This is sometimes used to make the plow run shallower by setting it low down. This is not right, for it then acts as a brake and makes the plow draw harder. The depth of the furrow should be adjusted at the clevis.
A plow not only has parts but it has character also.
CHARACTERISTICS OF A GOOD PLOW
A good plow should be strong in build and light in weight.
The draft should be as light as possible.
The plow should run steadily.
A good plow should not only turn the soil but should pulverize it as well.
When plowing, the team should be hitched to the plow with as short traces as possible, and the plow should be so adjusted that it will cut furrows of the required width and thickness with the least possible draft on the team and the least exertion on the part of the plowman.
