Up-Tight Plow From Sweden
Swedish farmer Lars Alden has adapted his semi-mounted plow for "up-tight plowing against fence lines, ditches and other inaccessible areas previously left unplowed.
"Leaving these unplowed areas, we create weed banks around the field. When we run alongside these weed banks with implements, we carry bits of weeds and weed seeds out into the field where we don't want them," explains Alden.
To solve the problem, he adapted his 5-bottom semi-mounted Kvernelands plow so that its rear land wheel, which normally runs on unplowed land, runs in the plow furrow behind the rearmost bottom. The hookup gives the wheel a firm base on which to run. Together with the pilot wheel that runs on the land side, it controls plowing depth. The two wheels are each controlled by hydraulic cylinders connected in series.
Here, courtesy of Traktor journilen magazine, is a closer look at how the "uptight" plow works.
The disk coulter of the rearmost plow bottom becomes the outermost point on the left side of the plow. The two wheels are controlled by their respective hydraulic cylinders, which are connected in series. The flow of oil governs their position relative to the plow.
The frame member connecting the pilot wheel and furrow wheel is arched so as to provide additional clearance. The furrow wheel is steered by a double-acting cylinder, series connected to a corresponding cylinder mounted between the drawbar and the front part of the plow.
To provide clearance for the stroke of the steering cylinder, the feeding cylinder on the drawbar is mounted upright. The guidance system makes reversing out of corners in the field and into confined spaces easy.
The setting of the plow can easily be checked from the driver's seat by an indicator on thee drawbar, or by an indicator on the furrow-wheel axle.
For transport, the plow can be moved alongside the draw beam with the aid of the hydraulic system, or guided with the furrow wheel. In this way, the tractor and plow together do not require a turning radius any larger than that of the tractor alone. A patent application has been made for the system.
