Abstract: A quick attachment device (12) for releasably connecting an implement (10) such as a loader to a vehicle without special tools comprises a pair of uprights (26) connected to the implement and a pair of corresponding pedestals (32) mounted on opposite sides of the vehicle. Each upright (26) is cradled by trunnions (40) in notches (38) on the corresponding pedestal (32) and releasably secured thereto by means of locking pins (48). Removal of the pins (48) and appropriate actuation of the cylinders (22, 30) causing the implement (10) to fulcrum about extendable stands (52) enable selective attachment or detachment from the vehicle.

Abstract: A quick attachment carrier assembly (10) for releasably connecting an attachment (12) to a front end loader (14) comprises a pair of carriers (24) with top and bottom notches therein adapted to receive transverse pins (40, 42) on the implement. Pivotal hooks (46) are provided on the carriers (24) for engagement with the pins (42) for interconnecting the implement (12) to the loader (14). The latch hooks (46) are preferably secured together and controlled in common by means of a single lever (52) and plunger (56) which permit positive locking of both hooks in either the latched or unlatched positions.

Abstract: An apparatus for injecting slurry in a field has a wheeled slurry tank, a feed conduit communicating with the interior of the tank, a transverse manifold to receive slurry from the feed conduit, several slurry injector pipes spaced along the conduit, and either a slurry pump or air pressurizing means for moving slurry from the tank under pressure for discharge through the feed conduit, the manifold, and the injector pipes. In all the slurry injector pipes are identical flow controlling and equalizing elements which have a single orifice and which are formed of elastomeric material which can flex to facilitate passing solid debris through the orifice. The orifice size provides a positive pressure head in the manifold so all the pipes deliver substantially equal quantities of slurry per unit time under varying conditions of operation.

Abstract: A baling apparatus of the type which is moved along a windrow of fodder and rolls a large bale in a baling chamber which has side plates to confine the ends of the bale. One side plate is mounted for lateral translatory movement, provided by a hydraulic cylinder unit, so as to reduce the confining pressure on the bale at the time of bale discharge. Bale formation and discharge are also improved by providing the baling chamber with a set of closely spaced, transversely extending rotatable rollers which support the bale during bale formation and discharge.

Abstract: A scraper assembly is connected at a forward and rearward end to a cable driven by a reversible double drum cable drive. The scraper assembly includes a scraper blade pivotally connected to a shaft secured at each end to a shoe, or runner. A strut extends forwardly and rearwardly from each shoe terminating in centrally disposed front and rear guide members. A drive linkage, connected at forward and rearward ends to the cable, is pivotally connected to the blade and has front and rear slide members which are slideably received within the front and rear guide members, respectively. The slide members have stops at their ends defining a limited range of sliding movement between the guide members and the drive linkage. The sliding movement of the slides in the guides pivots the scraper blade, with the slide stops transmitting a drive force to the guides at the end of the slide travel to move the blade forwardly or rearwardly.

Abstract: A device for wrapping twine around a bale of fodder which is rolled in a baling chamber of an apparatus that moves along a windrow. The device has a twine arm which swings between a transversely extending rest position and a dispensing position extending rearwardly into the baling chamber, a twine clamp near the rest position of the free end of the twine arm, a twine cutting blade near the twine clamp, and a mechanism that operates automatically in response to swinging movement of the twine arm to release the twine clamp as the arm approaches dispensing position and to re-engage the clamp and sever the twine as the arm approaches rest position. The mechanism includes a tension spring that passes overcenter to rapidly release and engage the clamp.

Abstract: A ventilating system for a swine shelter including an air inlet device located on the prevailing wind sidewall of such shelter and an air exhaust device on the other side of such shelter. The air inlet and exhaust devices include fans controlled by timers and thermostats so as to maintain a closed-shelter, controlled-environment type of confinement system. The air inlet is located within the eave of the shelter but the air exhaust is located so as to accept air from the manure pit only. A second air inlet and air exhaust are provided for use in the non-winter months.

Abstract: A parking stand for supporting an implement such as a front end loader when the implement is not in use including an extendable, elongated support leg pivotally secured near its upper end to a portion of the implement, a pin assembly for fixing the support leg in a plurality of extended positions, interlocking connection apparatus for retaining the support leg in its non-operative position and apparatus for limiting the pivotal movement of the elongated support leg.

Abstract: A quick connect and disconnect device for releasably attaching an implement such as a front end loader to a tractor in which the implement includes side frame members adapted for positioning on opposite sides of the tractor. The device includes a side support bracket on each side of the tractor, a connection means having an opening and means for securing and releasing the same relative to the side support bracket, a foot portion connected with the side frame members with a second opening for alignment with the first opening of the connection member, and a pin member for extension through the aligned first and second openings.

Abstract: A bale wagon for loading, unloading and transporting bales of hay, straw or the like of a size not capable of being handled and maneuvered by a single person comprising a wheel mounted, bale supporting frame, a bale loading means pivotally mounted to the frame at its forward end, means for conveying said bales from the forward end of the frame to a selected position therealong, a tongue section connectable to a draft vehicle and disposed in an operative position such that the wagon trails the draft vehicle to one side thereof and a wheel means for supporting the side of the frame opposite the tongue section when the tongue section is in its operative position.

Abstract: A trailer includes a tongue which may be pivoted from a center position to either side by operation of one of the brakes on the ground support wheels. A L-shaped loading fork is provided at the forward end pivotal from a position where the forwardly extending legs of the fork move under the bale to a position where they extend upwardly and the other legs extend rearwardly along the trailer frame. A pair of conveyors are provided along the length of the frame for moving the hay from one end to the other and for unloading the hay. An unloading apparatus is provided at the rear end which includes oppositely disposed upstanding posts having vertically pivotal arms to which are connected horizontally disposed stub shafts for engaging the bale at its axial center. The bale is rotated by engagement with a conveyor on its lower side thereby unrolling it as it is rotated.
