Abstract: A pair of rake wheels in an assembly is referred to as a center splitter assembly. Each rake wheel is configured for free-rotation, meaning it is powered by contacting the ground. The center splitter is used to separate material, each wheel moving material in a different direction. The rake wheel on the left side of the center splitter assembly will rotate in a clockwise direction, as viewed from behind the wheel, which will cause the material to move from the right to the left. The opposite applies to the rake wheel on the right side of the center splitter assembly, where it will rotate counter-clockwise, moving material from the left to the right. Since these rake wheels are attempting to move material in opposite directions, the spacing between the wheels has been found to be critical.

The arm is constrained to the frame so as to selectively move between a first operating condition in which the operating tools are in cooperation with the ground, and a second inactive condition in which the operating tools are raised from the ground in a position substantially parallel to the ground itself. The agricultural machine includes articulation members, interposed between the frame and the arm and includes a first positioning portion attached to the frame and a second positioning portion to which the arm is constrained. The first positioning portion and the second positioning portion are pivoted with respect to each other by elements of an articulation pin, in order to move the arm between the two conditions, operating and inactive.

Abstract: A single action hydraulic cylinder is utilized to rise a rake arm from the operating position to the transport position. An elastic mass is provided between the outer body of the hydraulic cylinder and an adjusting device, such as a nut on the stem of the cylinder. When the cylinder is actuated to rise the rake arm, the stem extends out of the cylinder body, thus freeing the elastic mass from the contact with the cylinder outer body. When lowering the rake arm to its operative position, the stem retracts and the elastic mass comes in contact with the cylinder, thereby acting against the retracting action and limiting the downward movement of the rake arm. The elasticity of the elastic mass permits small vertical movements of the rake arm to accommodate unevenness of the ground. Other versions and methods are also disclosed.

Abstract: A grooming apparatus, for sloping, aerating and fluffing bedding material in livestock free stalls, is attached to a vehicle such as a skid steer. The grooming apparatus includes a rotary arm, having grooming members, and connected to the vehicle by a boom. The rotary arm, when viewed across the stalls, is angled at a slope. The grooming members contact the bedding material to fluff and aerate it, and arrange it according to the slope. The rotary arm, when viewed from the end of a stall, may be pitched forward or rearward. These pitches and angles permit the grooming members to more effectively move the bedding material within each stall to create the slope. Such a slope is beneficial for livestock that prefers a sloped bed. Using the boom, the rotary arm can be moved up and/or out of the way when the vehicle is moved through doorways and the like.

Abstract: A haymaking machine in which fork-bearing arms are mounted in a pivoting fashion on a ring. These fork-bearing arms are controlled so that they can pivot about their respective longitudinal axes during rotation of the ring via a belt driving the ring and which is located at least in part near said ring, so that the area near the center of the rotor is clear. The fork-bearing arms are controlled in such a manner that their forks extend approximately vertical and will gather plants approximately on the entire forward half of their trajectory and that subsequently they are raised and the plants are deposited gently in the form of a swath. In this way the forage does not undergo any loss and it is not necessary to have a second rotor which works together with the swathing rotor in order to form a swath. Since the central part of the ring remains unobstructed, this allows passage of parts of the support frame and/or devices used for controlling the spacing with respect to the ground of the working forks.
