1. In a skip row cultivator havinga. an elongated horizontal tool bar,b. a plurality of moveable plow shanks on the tool bar,c. a plow on the bottom of each moveable shank;
- wherein the improvement comprises the following structure for moving the plows into cultivating position;
d. a hydraulic cylinder interconnecting each shank and the tool bar,e. each cylinder having(i) an up position wherein the plow on the shank is out of cultivating position, and(ii) a down position wherein the plow on the shank is in cultivating position,f. each cylinder having(i) an up connection wherein if hydraulic pressure is applied thereto the cylinder is moved to the up position, and(ii) a down connection wherein if hydraulic pressure is applied thereto the cylinder is moved to the down position,g. a first hose line connected to the up connection on half the cylinders and the down connection on the remainder of the cylinders,h. a second hose line connected to the other connections,j. a source of hydraulic fluid under pressure, andk. a valve connecting the source of fluid selectively to the first or second hose lines.

Abstract
The moveable plow shanks upon a skip row cultivator are mounted for vertical sliding motion. Each shank has a hydraulic cylinder connected to it by a flexible hydraulic line so that the tool bar to which the shanks are connected may be folded. By selectively energizing the hydraulic cylinders by a single valve, alternate cultivators are placed in the cultivating or non-cultivating position.

10. In a skip row cultivator having
a. an elongated horizontal tool bar, (i) said tool bar having a wing on each end of the central portion thereof, (ii) said wings being foldable upward, b. a plurality of moveable plow shanks on the tool bar, each wing carrying at least one of said moveable plow shanks, c. a plow on the bottom of each moveable shank; -
wherein the improvement comprises the following method of moving the plows into cultivating position; d. connecting a hydraulic cylinder between each shank and the tool bar, e. moving each shank up and down by its hydraulic cylinder, f. connecting every other hydraulic cylinder by a first flexible hose so that pressure in the hydraulic hose will move the shanks into a down position, g. connecting the remaining cylinder by a second flexible hose so that pressure in the second hose will move the remaining shanks into a down position, and h. pressurizing one or the other hose.
