Side-hill plow.
A plow whose cutting apparatus is reversible, so as to throw its furrow-slice to the right or left, as may be desired.
This enables the lead horse of the team to return in the furrow just made, the plow throwing the soil down hill while traveling in either direction.
This saves the time of going back empty with the ordinary plow when the hill is too steep to allow the furrow to be thrown up hill.
It was originally invented by a Scotchman,
a Mr. Gray, and was improved by
Smith of Deanston and by
Wilkie of
Addington.

Turn-wrest plow. |
The English form of this plow has been in use for many years, being intended, as its name indicates, for plowing down hill with a back-and-forth furrow.
It is called in
England a
turn-wrest plow.
“The beam, head, and sheath are placed in the direction of a line passing through their middle; and the two handles are placed equidistant on each side of that line.
There are two mold-boards and two colters, and a mold-board is produced on either side at pleasure by moving the lever
a, between the plow-handles from one side to the other.
The line of draft can be shifted with equal ease and expedition, and at the same time one of the colters raised up clear of the land, and placed along the side of the beam, whilst the other is put down and placed in a proper position for cutting off the furrow-slice from the land These operations are performed by the plowman without changing his position between the stilts, by simply shifting two levers,
b c and
d a.” — Loudon.
Hay's
turn-wrest (
English) has a right-handed body and a left-handed one placed end to end, its beam and handles turning on a pivot at the center of the body.
There are several
United States patents of the same kind.
Huckvale's is so constructed that, by reversing the position of the handles, the body part is turned, and the sole becomes the landside, or
vice versa; the share becoming the colter, or the colter the share, as the case may be.
Wilkie's
turn-wrest plow (British) has two complete moldboards and shares connected by bars to a rod, which form the axis on which they rotate when moved by an adjusting-rod between the handles.
The same colter and landside answer for either the right or left hand plow.
The rod extending to the colter.
in moving the mold-board, moves also the colter one inch at the point so as to give it the proper position in the line of draft.

Reversing-movement. |
The American form of the invention consists in making the share, mold-board, and landside upon a piece which moves on a horizontal axis at the lower edge.
This is unlocked and partially rotated at the end of a furrow, converting the landside into a share and sole, and presenting the mold-board in the other direction.
