Abstract: A seed drill has rotatably mounted opener discs disposed in an acute angle with respect to the direction of travel and mounted on supports. A skid is mounted to each support at the outside surface of the disk at an angle with respect to the direction of travel. Each skid includes a trailing portion configured to have a sliding surface disposed above the depth of penetration of the disk in the ground and a leading portion bent upwardly in the direction of travel and having a recess in the side thereof facing the disk and which extends beyond the forwardmost portion of the disk in the direction of travel.

Abstract: An apparatus for producing ski tracks for a ski trail, comprising a sliding/planing body with a flat sliding surface which curves upwardly at the forward section of said body, and spaced-apart track-forming members depending downwardly from said sliding surface. The track-forming members each comprising a bottom surface and two parallel side surfaces whose forward portions converge to form a plow portion while the bottom surface extends forward in full width beneath said plow portion and at least to the tip of it. A drag frame pivotally attached to the surface of the sliding/planing body rearward of its forward section. The axis of pivot for the frame running transversely of the direction of advancement for the sliding/planing body. The trackforming members producing a track with strong, compacted walls, without weighing down the apparatus.

Abstract: A depth control skid and seed boot assembly is disclosed that is particularly useful in a sod seeding implement for adjusting the maximum depth of cut of a cutting wheel and for adjusting the depth of the seed boot independently of each other. An arm rotatably mounting a pair of cutting wheels slidably receives the forward section of the skid. The rear of the skid is bolted to a bracket assembly vertically positionable with respect to the arm for adjusting the depth of cut. The bracket assembly pivotally carries the seed boot which is yieldingly and adjustably held in position with respect to the ground by a bolt and spring assembly. The seed boot can pivot upwardly against the bias of the spring out of the way of obstacles.

Abstract: A farm implement having a main frame; at least two carriage wheels for supporting the frame; a plurality of brackets mounted in pairs on the frame, each pair of brackets defining a sled; a plurality of knives mounted on each sled in a generally horizontal plane; a weeder bar rotatably supported by the brackets; and a hydraulic motor mounted on the frame for driving the weeder bar in a counter clockwise direction as the implement is moved in a direction whereby the carriage wheels rotate in a clockwise direction.

Abstract: An elongated main frame is provided including front and rear end portions. An elongated dual track endless track drive assembly is oscillatably supported from the rear end portion of the frame for angular displacement about a first horizontal transverse axis intermediate the opposite ends of the track drive assembly. A front dirigible ski equipped support assembly is carried by the front end portion of the frame forward of the drive assembly and an elongated longitudinally extending sub-frame including front and rear end portions is supported from the main frame front end portion for angular displacement about a second horizontal axis extending transversely of the main frame and the front end portion of the sub-frame. The rear end portion of the sub-frame includes transversely spaced depending packed and icy snow cover working times and an upstanding transverse blade member rearward of the tines including a generally horizontal lower edge portion.

Abstract: A device adapted to be attached to a vehicle for plowing snow on gravel covered roads while minimizing loss of gravel caused by plowing which employs a horizontally elongated blade having a concave plowing front surface and a convex rear surface.A horizontal foot is disposed below the blade and is adapted slidably to rest on the top of a gravel road covering. A mechanism secures said foot to said blade in such manner that the bottom edge of the blade is disposed above the foot. The mechanism is manually adjustable to adjust the vertical separation between the bottom edge of the blade and the bottom surface of the foot to a distance at which the gravel will not be removed and the snow can be suitably plowed when the device is used on a vehicle.

Abstract: An apparatus and more specifically a drag adapted to form and condition a ski trail, and in particular two generally parallel ski traces as commonly used for cross-country skiing, such that the ski traces are of uniform parallelism and depth and are free of lumps of ice and snow. This drag includes a rear sled unit and a front unit, a pair of runners forming ski traces secured under the sled unit, a pivotal connection joining the two units and allowing only up-and-down sliding and yaw pivoting of the rear unit relative to the front unit. The rear unit includes a sled platform and a pair of runners of particular construction to cooperatively produce ski traces of uniform parallelism and depth. The front unit includes a frame carried by a runner and adjustable height relative to the latter, scrapers pivoted to the frame of the front unit between a downward operative position and an elevated inoperative position.

Abstract: Apparatus for towing behind a tow vehicle to handle and condition snow on ski slopes, including a ripper assembly having teeth for ripping the surface of the snow, a scraper assembly for scraping the surface of the snow and to redeposit quantities of accumulated snow in low areas, a roller assembly for compacting loose snow and a drag assembly for dragging the surface of conditioned snow.

Abstract: This invention proposes a long-distance ski-track-ploughing device comprising a track sled adapted to be towed by a vehicle in the direction of the track, the underside of the said sled being equipped with tracking elements oriented in the direction of the track. This device is characterized in that the track sled is preceded by a forward sled, joined to the track sled by means of a connecting frame to which each sled is connected pivotably by means of a horizontal axis perpendicular to the direction of the track, the said connecting frame carrying a scraper perpendicular to the direction of the track and located between the said sleds.

Abstract: A cultivator for conditioning the earth surface along row crops, the cultivator having a frame adapted for earth traversing movement along rows of such crops; scraper blade assemblies mounted on the frame for floating action; and earth surface engaging, blade depth control skis affixed on the assemblies and forwardly extended therefrom elevationally controlling the scraper blade assemblies in response to the earth traversed thereby.
