Abstract: A tractor includes a working motor, a work machine including a roller configured to rotate by an output from the working motor, a support mechanism configured to support the work machine such that a working posture and a retracting posture are achievable, and a control device. The control device executes: an adherence amount acquisition process of acquiring an estimated adherence amount as an estimated value for the amount of mud attached to the roller; and a mud removal process of, when the estimated adherence amount is equal to or more than a determination adherence amount, removing the mud from the roller by driving the working motor in a state where the work machine takes the retracting posture.

The first disk (160) is oriented at a second acute angle relative to the ground surface. A second disk (166) is supported on the second spindle (168), wherein the second spindle (168) is oriented in a second orientation and at a third acute angle relative to the lateral line. The second disk (166) is oriented at a fourth acute angle relative to the ground surface. The first disk (160) is longitudinally offset ahead of the second disk (166), and there are no structural components between the first and second disks (160, 166) other than the first and second spindles (164, 168).

Abstract: A process for and a machine which builds levees in gumbo with moldboards which have knives welded to a blade which makes strips and then lumps of a sheet of gumbo. The machine is attached to a tractor by a three point hitch. The moldboards are adjusted by plates and discs which are connected by bolts in various holes in the plates and discs. A push board is attached to the rear of the machine for repairing damaged levees.

Abstract: A bedding plow suited for forestry planting operations includes a plow frame that is attached to a tractor or other tow vehicle. The frame holds a pair of trailing disk assemblies that are arranged along opposite longitudinal sides of the bed being plowed. A center-cut disk assembly is mounted pivotably to the frame between and forwardly of the trailing disk assemblies. A resilient biasing assembly such as a hydraulic or pneumatic relief mechanism interconnects an arm of the center-cut disk assembly and the frame. The resilient biasing device urges the center-cut disk assembly to engage the ground under normal circumstances and permits the disk assembly to retract upwardly and ride over obstructions that are encountered while the plow cultivates the bed.

Abstract: In a tillage device having first and second plow assemblies mounted in parallel relation on a main frame to thereby cut furrows in the soil creating soil strips in so doing and depositing the soil strips on a berm between the furrows created by the plow assemblies and having a rearwardly located plow assembly for moving the soil under the berm outwardly into the first and second furrows thereby creating a middle furrow and allowing the soil on the berm to fall into the middle furrow.

Abstract: The present invention provides a shankless strip tillage tool for no-till preparation of surface soil for the planting of seeds. The strip tillage apparatus has a frame for mounting the apparatus to a tool bar mounted on a draft vehicle. The frame has a pivotally mounted tandem walking beam with a pair of angled coulters rotably mounted on the walking beam for displacing soil. The angled coulters displace soil as they are pulled through the soil by the draft vehicle and urges the soil toward the center of the strip to accomplish the no-till preparation.

Abstract: A subsoil plowing implement having winged subsoil plows that break and lift the soil thereby loosening said soil. The plows are mounted so that an upper surface of the wing of the plow may be oriented at varying degrees of incline to horizontal. Spikes are located at a leading edge of the wing and a shank so that said spikes precede the wing and shank through the soil. The spikes initially break the ground and reduce the resistance that the wing and shank experience as they progress through the soil. A bevelled and sharpened deflection strip fixed to a leading edge of the shank making said shank more knifelike and allowing it to cut through the soil with reduced friction. By varying the arrangement and orientation of the plows, areas of loosened soil with different cross-sectional shapes are created.

Abstract: The mixing head comprises a pair of opposed, spaced apart, generally vertical discs that are generally aligned with the direction of travel, although they are slightly angled so as to be wider apart at their front ends than at their rear ends. The discs are rotatably mounted to a free floating frame. Each disc has a plurality of radially extending, elongated, broad, rigid, chisel-like teeth which extend from the disc central portion out beyond its circumferential rim. The discs are driven to rotate against the direction of travel. When rotating, the disc and teeth formations operate to cut down into the coil and excavate it in portions carried by the teeth. The portions are moved inwardly by the angled formations and then thrown and dropped to the rear. The furrow formed has a flat-topped ridge overtopped with a loose mix of excavated soil and humus. The furrow is a good growing site for implanted seedlings.

Abstract: A moldboard plow apparatus having alternate and cooperating moldboards or so-called "scoops". The first of the moldboards digs out and lifts a first soil section from a ground surface thereby forming a first furrow or so-called "cut". The second moldboard or so-called "scoop" cuts and lifts a second soil section thereby forming a second furrow, parallel to and usually adjacent to the first furrow. The moldboards are shaped such that a rearward movement of the soil sections on the respective moldboards causes the soil sections to be inverted and thrown from the moldboards into the opposite furrow in an upside-down condition. Thus the first soil section is thrown into the section furrow and the second soil section is thrown into the first furrow.

Abstract: An excavating bucket having spaced sides attached to a rear wall and a flat bottom which lies in a curved plane. The sides and rear are joined to the bottom, and the bucket opening has a periphery defined by the upper edge portion of the rear wall, sides, and the forward edge of the bottom. The marginal, forward end of the bottom is in the form of a bucket lip. A plurality of digging teeth are mounted to the forward end of the lip and arranged respective to one another to provide a continuous cutting edge from one to the other side of the bucket. The geometrical configuration of the digging teeth, together with the bucket design and tooth distribution pattern, increases the digging efficiency and provides a smooth excavated surface.

Abstract: A device for use in measuring blood pressure comprises a cuff which is windable around the portion of a body and a clamp fastener for maintaining the cuff in the wound position during use. The fastener has a box shaped outer part and a box shaped inner part which is moveable therein perpendicular to the longitudinal access thereof and has slots in its end faces for receiving a pressure rod about which the cuff is looped. A sound pickup is disposed in the pressure chamber of the cuff and is connectable to a display instrument via an air tube.

Abstract: A soil stabilizer comprises a front bank of four ploughs inclined at 45.degree. to the direction of movement and a similar rear bank of ploughs. The ploughs are arranged in pairs whereof the front ploughs toss the soil/stabilizer mixture to one side where it is engaged by the rear plough which tosses to the other side. The ploughs are mounted on a frame which may be carried by pivoted arms on a road grader or may be mounted on ground engaging wheels.

Abstract: A plow implement which completely plows and breaks the entire surface of a field being plowed in a single pass. This plow completely pulverizes the soil by means of upright cutting blades on double-opposing moldboard plows and single moldboard plows. Additional single sweeps and deep cutting sub-soiler devices may be provided with the over-all implement.
