Abstract: A seeder including a chassis including a substantially horizontal transverse beam on which seeding elements are distributed in a regular manner, the transverse beam including a central section and two lateral sections arranged on either side of the central section in a work position, and being raised substantially above the central section in a transport position, each lateral section being connected to the chassis by a respective arm and being displaceable transversely and vertically with respect to the chassis by a deformable mechanism controlled by an operating jack. In the seeder one deformable mechanism is offset with respect to the other deformable mechanism, taking into account a direction of advance.

Abstract: A berm building disc is designed to reduce the amount of soil that builds up on the inner surface of the disc as the disc pushes soil for berm formation. The disc has a disc body having an outer radial edge, and defining an inner concave surface and an outer convex surface. Features are formed on the inner concave surface to reduce the surface area or soil adhesion properties of the inner concave surface.

Abstract: An apparatus for positioning a work object relative to a primary support between first and second positions, the apparatus having a first mount adapted to be mounted on the work object; a second mount adapted to be mounted on the primary support; a linking assembly interconnecting the first and second mounts; and a control system interconnecting the work object and the linking assembly for selectively applying force to the linking assembly to move the work object between the first and second positions.

Abstract: A trailing harrow attachment is pivotally connected to the aft end of support arms for rotation about a transverse axis between a field-working position wherein the harrow tines engage the soil, and a non-operative position wherein the harrow is rotated about the axis by approximately 180.degree. so that the tines extend away from the ground to provide better trash flow and ground clearance. The angles that attach the harrow to the trailing arms include apertures located an equal distance radially outwardly on opposite sides of the axis so that the harrow may be pinned at the same location on one of the support arms in either the field-working or the non-operative position.

Abstract: A tool bar is provided with rotatable tool carrying sections having a quick release lock.

Abstract: An improved liquid chemical applicator is provided and consists of a mechanism that can activate a plurality of spray nozzles to apply a plurality of overlapping sprays of liquid chemical at a constant height, at a constant pressure and at a proper direction onto horizontal, vertical and angular surfaces to form a uniform coating thereon.

Abstract: To prevent the development of clods on the soil surface when using a soil layer cultivator for the deep loosening of a field or the like, a pressure roller is provided to travel over the soil surface rearwardly of the elements effecting the deep loosening of the soil. The pressure roller is made up of several sections mounted on a common shaft with the individual roller sections located between support posts on a frame tube which posts support the loosening elements. The roller sections may be hinged individually or in groups to the frame tube. The rollers may roll freely over the soil surface or a forced drive for the roller sections can be provided.

Abstract: An agricultural tool cart having structure for towing a three-point hitch seed planter behind minimum tillage tools for tilling and planting in one pass through a field, the cart being equipped with hydraulic operated wheels for transport of both minimum tillage tools and seed planter.

Abstract: An attachment for agricultural machines includes a frame having a leading and trailing portion, a first soil-treating unit located at the leading portion of the frame and a second soil-treating unit located at the trailing portion of the frame. Between the first unit and the second unit there is located on the frame wheels for supporting the frame when an agricultural machine provided with the attachment moves along a road. The wheels are displaceable relative to the frame between a first position in which the wheels engage the ground and a second position in which the wheels do not engage the ground. The frame is so coupled to a lifting device of the agricultural machine that, when the wheels are in the second position, the trailing portion of the frame is supported on the ground by the second soil-treating unit.

Abstract: Power operated mechanisms are provided to operate a foldup implement which includes a double-acting hydraulic jack interconnected between a foldup wing section and a main section. The jack has a lost motion connection with the main section permitting the wing section to float up and down about its longitudinal pivot connection to the main section during field operations. An elongated slot of the lost motion connection is so disposed as to minimize any tendency for the end of the jack associated with the slot to move from its position at the laterally outer end of the slot as the wing section is raised to its transport position. To further insure that the end of the jack will not shift from its position at the laterally outer end of the slot as the wing section is raised to a transport position, an abutment member is disposed above a part of the slot so as to abut the end of the jack in the slot should the latter tend to shift laterally inwardly while the wing section is in its raised transport position.

Abstract: A cultivator has a beamed frame with a coupling member that can be attached to the lower points of a lift device on a tractor. The cultivator has an assembly of blades mounted on a horizontal shaft which is driven via a forward transmission connected to the p.t.o. of the tractor. A power driven roller is turned by a rear transmission that is interconnected to the forward transmission by a telescopic shaft. The roller is mounted on a supporting structure including overhead beams that extend forwardly to a pivot connection on top of the coupling member. The roller is vertically displaceable and mounted on pivoted arms of the structure. Hydraulic assemblies can raise and/or lower the roller relative to ground wheels on the structure, for transport. A delivery mechanism including a hopper with a connectable feeder drive is supported on the structure in front of the roller. The roller can be driven to aid the forward travel of the implement.
