Abstract: A folding planter includes a frame formed by first and second frame members supported for relative, longitudinal shifting movement, a primary fluid-actuated piston and cylinder assembly for shifting the first and second frame members between retracted and extended positions, and a pair of planter assemblies each supported on the second frame member for pivotal movement about a vertical pivot axis between an extended planting position and a retracted transport position. Each planter assembly includes a tool bar that extends transverse to the longitudinal axis of the frame in the planting position and parallel to the frame in the transport position, and a plurality of planting units supported on the tool bar. A pair of elongated trusses are connected between the first frame member and the planter assemblies.

Abstract: The working depth of obliquely angled disc gangs on the implement can be readily adjusted from the tractor seat with a single hydraulic cylinder through the use of mechanical linkage that couples the hydraulic cylinder with all of the disc gangs for simultaneous movement. Special pivots that join the gangs to the main frame permit the gangs to be manually angled adjusted without affecting depth, and vice-versa, while quick-release locks securely hold the gangs in their selected angular positions yet permit rapid adjustment.

Abstract: An elongated trailer includes a bed supported on an undercarriage, wherein the undercarriage is shiftable longitudinally between roading and loading positions. At least one beam is provided on the bed and includes a lower flange defining a tracking surface, a web extending upward from the central longitudinal axis of the flange, and forward and rear ramps formed in the tracking surface. The forward and rear ramps are spaced longitudinally from one another and extend laterally inward from opposite sides of the tracking surface. The ramps are of a width greater than one half the width of the tracking surface so that the ramps overlap one another when viewed along the central longitudinal axis, and each ramp extends beneath the web. A pair of rollers are supported on the undercarriage for rotational movement and bear against the central longitudinal axis of the tracking surface and engage the ramps when the undercarriage is shifted to the roading position.

Abstract: A tillage implement which has both deep tillage subsoil shanks at the rear of the machine and relatively shallow running, residue cutting and topsoil mixing discs at the front of the machine provides for expeditious depth adjustment of the discs through spacer blocks that may be inserted between the underside of the frame of the implement and the tops of the gang beams. The blocks are designed to be clamped in position beside pivot bolts and angle retaining bolts of the gangs such that the blocks may be inserted or removed by merely loosening the bolts instead of completely removing the same and without interfering with the ability of the gangs to be angle adjusted fore-and-aft. The configuration of the blocks is such that they may be stacked one upon the other to provide an increased range of depth adjustment without sacrificing rigidity of construction.

Abstract: A trailer having a tiltable main deck and a shiftable undercarriage includes an undercarriage assembly having a deck support structure mounted thereon for supporting the deck. The deck support structure includes lifting arms for lifting the elongated deck assembly relative to the undercarriage independently of the undercarriage shifting mechanism so that the deck may be lifted relative to the undercarriage without simultaneouly shifting the undercarriage along the deck. The trailer may include a hitch assembly that permits the trailer to be pivotally connected to a towing vehicle to permit the forward deck to be tilted away from the main deck to increase the angle between the main deck and the forward deck when the trailer is in the unloading position. Further, a deck angle adjustment assembly is disclosed for adjusting the relative positions of the decks.

Abstract: An adjustment means for a cultivator disc which provides lateral, vertical and angular adjustment means. A plurality of discs are mounted in parallel on a gang frame, and may be individually adjusted in the field to exact, predetermined positions established by a positive positioning means, and then firmly held in place by a clamping means. In the presently preferred embodiment, the individual support shafts of each cultivator disc are supported by the angle adjustment brackets, which are supported by the lateral adjustment brackets, which are slidably supported in predetermined fixed positions in lateral housings attached to the main towing bar of the cultivator assembly.

Abstract: The self-loading tilt bed trailer has an elongated tiltable bed normally disposed in a substantially horizontal road traveling position that may be tilted about a transverse horizontal axis to a downwardly and rearwardly inclined position. The bed is pivotally coupled at its front end to a towing tractor for pivotal movement of the bed about a substantially vertical axis. When the bed is tilted steeply enough to raise the wheels completely off the ground so the weight of the bed is supported only by a ground-engaging pad at the rear of the bed and the tractor at the front, actuation of a hydraulic cylinder associated with the pad causes the rear of the bed to be shifted a short distance to the right or left relative to the stationary pad, pivoting about the upright hitch axis at the tractor.

Abstract: A structure for buckling the frames of a two-sectioned, centrally articulated truck chassis has a pair of links swingably mounted on the front frame and pivotally connected to a piston and cylinder power assembly carried by the rear frame. Additionally, a control member in overlying, vertical alignment with the piston and cylinder assembly swingably connects the links to the rear frame. As the piston is actuated, the force directly bears on the links, causing the latter to swing and simultaneously move the control member, causing the frames to move upwardly and spread while tilting about their articulation. The entire force presented by the rear mounted cylinder and piston assembly bears directly on the opposite, front frame such that a minimum amount of power is required to effect the tilting. Also, the vertical alignment of the piston and cylinder with the control member reduces bending and bowing stresses in the structure.

Abstract: A truck in the nature of an automotive vehicle for carrying and moving heavy loads, bulky articles, freight, etc., has a wheeled front section which includes a cab and an engine compartment and a wheeled rear section which includes a cargo-receiving bed. The two sections are articulated to permit raising of the truck at the articulation or joint between the sections, causing the front section to slope downwardly and forwardly from the joint and the rear section to slope downwardly and rearwardly from the joint, resulting in the bed being positioned in a small angle of inclination relative to the plane of the surface which supports the truck such as to facilitate loading and unloading. The bed is reciprocable fore and aft of the rear section by use of hydraulic power means for placing its rear ramp against such surface, and a linkage system, also hydraulically powered, effects the tilting operation.

Abstract: A control assembly for shifting the undercarriage of a trailer to a position permitting tilting of the bed for facilitating loading of cargo has a relatively long stroke such as to appreciably decrease the slope of the bed when in its tilted position with the undercarriage disposed forwardly remote from its normal roading position. The assembly permits the loading of cargo which would otherwise require additional ramps needed also in certain instances to compensate for overhang.

Abstract: Through adaptation of and improvement upon secondary, minimum tillage techniques, there is provided a single pass, seedbed method and agricultural machine, utilizing reduction, incorporation, aeration and other procedures, capable of effectively handling all types of adverse field conditions, ground compositions and soil makeup in such manner as to quickly, easily and inexpensively convert all materials and substances therein contained or to be added thereto from a state generally unsuited for seeding and satisfactory plant development to a finished condition wherein any desired seed type may be thereupon planted, sowed or set thereinto without difficulty and with an assurance of good germination and strong, healthy crop growth unimpaired by wind and soil erosion, ineffective moisture retention and other impediments which otherwise normally reduce or destroy profitable harvesting results.

Abstract: A tiltable trailer is provided with longitudinal beams spaced such as to be located directly beneath the wheels of equipment to be hauled thereby, eliminating the need for heavy cross pieces beneath the deck for the supporting wide loads, thereby contributing toward decreased trailer weight. A lower deck height is accomplished by having the tracks for the rollers of the reciprocable undercarriage and the ramps of such tracks located within the beams, by positioning the undercarriage between the beams and by providing the undercarriage with a low-profile beam support which, in turn, has roller-mounting cross members immediately ahead of and immediately behind the wheel and axle assemblies.

Abstract: A trailer having a tiltable bed and a wheel-supported undercarriage is provided with structure mounting the undercarriage for reciprocal movement fore and aft of the bed between a forward, bed-tilting position and a rearmost, roading position wherein the bed is carried lower to the ground to accommodate higher loads. The mounting structure includes a pair of tracks on the bed and a series of ramps for raising the bed relative to the undercarriage when the latter is shifted from its roading position such that sufficient spacing between the bed and the undercarriage is provided for clearance of the bed understructure during movement of the undercarriage along its fore and aft path of travel.
