摘要： A tractor comprising driven front and rear wheels, and a front and rear lifting device. The front wheels are in sets of two wheels mounted on king pins so as to be steerable through an angle of one hundred, twenty-five degrees or more. A divided track rod is connected to the king pins for steering purposes. The track rod has two parts, each centrally pivotally connected to a centrally pivoted lever and outwardly pivoted by a lever to a corresponding king pin. The latter levers extend forward and the track rods are pivoted to the central lever at a location to the rear of a plane containing the king pins. Shafts connected to the tractor's engine for turning the forward wheels extend through the king pins. The king pins are inclined upwardly to the rear and can turn each front set of wheels transverse to the straight-ahead direction of travel sufficiently to permit removal of the then foremost wheel.

摘要： An agricultural tractor having six wheels which are each hydraulically drivable by individual hydraulic motors through hydraulic fluid supplied by respective hydraulic pumps. With each pump driving only one wheel, skidding of a wheel does not affect drive to other wheels. The pumps are all driven by a single engine. Selectively operable automatic control means control the speed of the wheels when, for example, the tractor is turning. Control means are also responsive to the drag resistance of an implement hitched to the tractor's lifting members and cause such lifting members to raise when the implement's resistance exceeds a predetermined limit. In addition, speed of the vehicle is automatically reduced by reason of such resistance and, further, the position of the implement relative to the ground may be adjusted to offset at the location of the implement upward and downward movement of tandem wheel pairs at the rear of the tractor. Such adjustment is effected by the lifting device and is delayed for a short period to allow movement of the vehicle.

摘要： A plow has coupling members at its forward side for connection to a multi-point hitch of a tractor. Furrow slicing members at the front form furrow slices which are elevated to furrow turning drums during operation. The furrow slices are turned about their longitudinal axes and deposited to the rear by the rotating drums. The drums are mounted on rollers and driven to rotate about upwardly and forwardly extending axes at preselected speeds. Projections within the drums turn the furrow slices which can be inverted and deposited to the rear.

摘要： In a soil cultivating implement of the kind which comprises a row of rotary power-driven soil working members which extend substantially horizontally and perpendicular to the implement's intended direction of operative travel, the cost of making and assembling the implement is reduced by providing a drive transmission to the soil working members which includes an upright shaft fixed in a sleeve of an open-bottomed gearbox. A bevel pinion is rotatable around the lower end of such fixed shaft and is fastened by adhesively secured pins to the top of one of the spur pinions, each of which is welded to the upper end of a rotary shaft carrying the corresponding soil working member. Blades are provided adjacent the bevel pinion and nearby spur pinions to distribute lubricant to such pinions. One lifts lubricant to the intermeshing spur pinions and another blade further guides same to the bevel pinion.

摘要： A tractor having three sets of twin pneumatic tires mounted on wheels on each side of the tractor, a track being received around three, in one embodiment and two in the other of such pneumatic tires. In each embodiment only the rearmost set of wheels is powered directly from an axle rather than via the track. The track is a belt of flexible material which in the first embodiment has a plurality of traction members secured thereto by bolts extending through the belt and secured on the inner side by a strip opposite the traction members, such strip having a V-shaped portion which is received between the twin tires to retain the track in place. Each such traction member includes a part flush to the belt through which the bolts are received, a further part extending from the first part outwardly and normally to the belt and a ground engaging part extending from the second part in a direction parallel to the belt. The traction member in cross-section thus may alternately appear as an inverted U with outwardly extending flanges or as a "C" with square sides or as an inverted "T" or the like whereby, in other embodiments, the ground engaging portion of the traction member has at least one flange extending away from the second part of the traction member. In operation, the traction members tend to become biased when propelling the tractor under tension so their ground engaging parts are inclined downwardly relative to the ground from the tractor's direction of travel.

摘要： An overload coupling member is used as a strut to interconnect the upper link of a tractor lift device with an implement, such as a cultivator. The member includes two portions that are moved towards one another upon overload to allow the implement to pivot upwardly on the other two links. One portion has an inner end sleeve pivoted to a further sleeve on the other portion's inner end and relative movement between the two portions is prevented by a shear pin that extends into an opening of the sleeves. Upon overload, the pin shears and the portions jack-knife until the lift raises the implement past the obstacle and the implement is then lowered. The inner opening end is normally closed by an abutment member, but when the portions are pivoted, the opening is exposed and a severed pin portion falls out. The shear pin can have a number of severable portions and be spring biased to slide in a holder and establish rigid connection between the two portions a number of times. In another version, the portions can be a cylinder and a piston with rod respectively. On either side of the piston fluid spaces are interconnected through a circuit having a pressure relief valve. The valve is biased by a spring that can be set to yield when the pressure exceeds a predetermined value. A by-pass conduit also allows movement of fluid from one space to the other accompanied by the movement of the piston in the cylinder. Thus, a set screw in the conduit can be used to open the conduit until the portions are set in desired relative positions and the member has the correct overall length.

摘要： A standard model truck or trailer having a rear load bearing axle with two side-by-side pneumatic tires mounted on wheels at both ends of the axle is provided. A further set of like side-by-side rear wheels with pneumatic tires are connected to the vehicle's main frame by depending carriers pivoted thereto. The rear wheels are rearwardly biased by a compression spring and may be selectively moved forwardly or rearwardly in an arc about their pivotable connection by a hydraulic piston and cylinder arrangement. An endless tread-type track can be mounted around the succeeding pairs of tires on either side. Each track has two or more parts dovetailed at the ends held together by a spring steel rod inserted in openings therethrough, each opening being defined by a polygonal tube which receives the rod whereby it cannot rotate. The rod is maintained in place by a detent member. A slightly curved plate, rectangular as seen in plan, pivoted from supports depending from frame forward of at least the rearmost wheels, extends rearwardly centrally between the wheels to where a hydraulic cylinder and piston assembly connects it to the frame to lift the wheels simultaneously for installing the tracks. They are installed by decreasing the distance between the wheels through the hydraulic arrangement and, when in place, by releasing pressure in the connected hydraulic piston and cylinder assembly whereby the compression spring tensions the wheels against them.

摘要： A plow has spaced apart furrow cutters and a furrow elevating structure that loosens and raises a continuous wide furrow strip to a furrow turning device during plow travel. The turning device can be an open ended drum that is rotated or stationary. Within the drum, a worm conveyor is rotated that first engages and depresses the furrow top, but as the furrow strip passes through the drum, it is inverted and to some extent, winds around the conveyor so that the furrow strip has a cross section that resembles an inverted shallow U. The inverted and deformed strip is deposited in the furrow being formed. The conveyor is normally located about centrally of the drum interior so that the furrow strip top is first engaged by the conveyor's lower surfaces, but as the strip is urged through the drum, it is inverted and supported on top of the conveyor before being deposited to the rear. The method of cutting, inverting and depositing the deformed continuous furrow strip is claimed.
