Frame plows.
Horse-drawn frame plows can be one- or double barrel. Instead of a bog, these plows have a frame, to which the plow bodies are bolted. The entire plow rests on two wheels: field and furrow and additionally rests on the heel of the last body. The field wheel is mounted on a double-bent axis - in the form of a crank. The axle of this wheel can be turned by a hand lever around the point of seating in the frame by an angle of 90 ° [1,57 work]. The position of the field wheel is set by a ratchet on the segment toothed. The furrow wheel is also mounted on a bent axle, which through the so-called. the intermediate axle is connected to the linkage mechanism. When the plow bodies are in raised position, the manual adjustment lever is in the horizontal position, and its lower end - in the front extreme cut of the baffle. The plow wheels are then close to each other. If we release the latch with the hand lever, then the plow will drop its bodies under its own weight. Initially, the two wheels move apart from each other, but with the moment, when the lower end of the hand lever fits into the arched cutout of the baffle, the furrow wheel stops and only the field wheel will continue to retract - until the bodies rest completely on the ground. The hand lever will then be in an intermediate position between the vertical and horizontal positions. To set the plow bodies for plowing, use the hand lever to raise the field wheel yes, that the difference between the height of this wheel and the height of the furrow wheel and plow bodies corresponds to the desired plowing depth. Only for lifting the first furrows, the furrow wheel must also be raised accordingly. To do this, release the yoke securing the axle of this wheel to the intermediate axle, level the plow frame and re-install the furrow wheel axle in the desired position.
