    Abstract: A method of defining an end travel limit of an electric actuator includes sensing an electric current of the electric actuator while moving the electric actuator from a first position to a second position. A maximum travel current of the electric current sensed during movement of the electric actuator between the first position to the second position is increased by a factor to define a maximum calibration current. The electric current is then sensed while moving from the second position toward an end travel position of the electric actuator. Movement of the electric actuator is stopped at a fault position when the electric current equals the maximum calibration current. The end travel limit of the electric actuator is then defined as a function of the fault position.

    Abstract: An agricultural vehicle header having a frame, at least one support arm extending, a cutter assembly attached to the distal ends of the support arms, a draper belt with an upper belt portion located above the support arms, and a parallel linkage connected to each support arm to operatively connect the cutter assembly to the frame. The linkage includes upper and lower links. The upper belt portion extends along a cross-belt direction that is perpendicular to a travel direction of the upper belt portion, and the proximal pivots of the upper and lower links are positioned on a line that is oriented at an angle of 60 to 120 degrees relative to the cross-belt direction when the header is in a freestanding static state.

    Abstract: The expanding coupler for a mower and lawn vacuum may pull a suction hose adjacent to a deck adapter outlet. A plurality of hose springs may allow the suction hose to separate from the deck adapter outlet when the suction hose is pulled. The shroud may direct clippings from the deck adapter outlet to the suction hose when the suction hose is separated from the deck adapter outlet. As a non-limiting example, the suction hose may couple a deck adapter of a lawn vacuum to a suction hose adapter of the lawn vacuum. The suction hose may be pulled when the riding lawn mower makes a turn in a direction that is opposite the side that the suction hose is on. Fasteners may prevent the suction hose from separating from the hose adapter.

    Abstract: A reel includes a plurality of bats and an end shield plate mounted on the end of the reel at the crop divider which has a peripheral edge radially inward of an outer tip of the fingers with an apex at each of the bats and portions which are recessed from a straight line joining the apexes. Each of the endmost fingers of the bats has a base which is axially inside the end plate and is bent longitudinally of the reel to define an outer tip which is axially spaced from the base to a position beyond the radial plane of the end plate. A plurality of molded paddle blades are mounted to project outwardly from the end surface to clear crop away from the space between the outer face of the end plate and the divider.

    Abstract: A float arm support system may include a float arm supporting an active member, the float arm being pivotable about a first axis, a skid shoe to bear against and follow local ground contours of the underlying terrain while supporting the active member of the float arm above the underlying terrain and a powered actuator. The skid shoe may be coupled to the float arm between the first axis and the active member. The powered actuator may be operably coupled to the skid shoe to vertically move the skid shoe to adjust a spacing at which the skid shoe supports the active member of the float arm relative to the underlying terrain.

    Abstract: A rake assembly, for the transfer and conveyance of agricultural products such as grass, hay, forage, wheat, corn and the like, cut and distributed on the ground, includes a framework which can be coupled to a drive unit for its movement along an advancement direction. The framework is associated with elements for lifting and delivering the agricultural products to at least one conveyor belt, which faces the elements and is proximate to them, for the transfer and conveyance of the agricultural products along a work direction that is defined by the belt, until the agricultural products are released in a corresponding unloading region. The assembly includes at least one elastically deformable plate, which is coupled stably to the belt and is at least partially directed, with one of its faces, toward the unloading region.
