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.
Abstract: A crop raking device includes a rake wheel and a gauge wheel. The rake wheel is configured to rake crop in a field, with teeth disposed around a perimeter thereof, and has a vertically variable position. The gauge wheel is attached to the rake wheel, and is configured to contact ground behind the rake wheel and maintain a height of the rake wheel teeth with respect to the ground. The gauge wheel is configured to maintain a substantially constant upright orientation regardless of the vertical position of the rake wheel.
Abstract: A rake has two side members attached perpendicularly to the rake so as to form an H-shaped frame system. A swivelable wheel is mounted at each corner of the frame. The frame fully stabilizes the rake in a position approximately level with a ground surface as the rake is pulled across the ground by a tractor or other vehicle. The wheels are adjustable both vertically and horizontally by inserting or removing rings on a shaft holding each wheel, and by telescoping parts of the frame into each other. The invention is useful either as a combined rake/stabilizer system, or as a kit for retrofitting existing rakes.

Abstract: The line of pull from a prime mover extends along a tongue assembly pivotally connected to a wheel rake frame assembly and intersects with the rear discharge end of the frame assembly when the rake is at its maximum angle of attack and with the extended longitudinal axis when the angle of attack is at its minimum thereby balancing forces on the rake and minimizing rake drift such that a consistent width of cut material can be raked.
Abstract: A towable hay rake is capable of being completely disassembled into parts having relatively homogenous dimensions, thus allowing the hay rake to be easily stored and shipped. In particular the hay rake of the present invention has the advantage that the entire rake can be packed into one rectangular crate of minimum encumbrance. This allows maximum possible practicality and efficiency in shipping and storage of the rake.
Abstract: A haymaking machine including at least one windrowing rotor which is articulated to a bearing structure in such a manner that it can pivot about at least one axis which is substantially horizontal and perpendicular to the direction of travel. The at least one rotor can be driven in rotation about a central spindle which is substantially vertical and which is fitted at its lower end with a support equipped with several bearing wheels at least one of which is situated behind the central spindle. The bearing wheel which is situated behind the central spindle of the rotor is connected to an arm of the support which includes a mechanism pressing the bearing wheel against the ground during windrowing work in such a way that it is constantly bearing against the ground and tends to cause the rotor to pivot downward on its front half about the articulation to the bearing structure.
Abstract: A hay making machine including a carrying structure which can be attached to a tractor such that the carrying structure can travel with the tractor in a forward direction. A substantially vertical support axle is mounted to the carrying structure and supports a rotor having hay making tools. A girder is attached to the support axle. A support structure is articulated to the girder via one substantially vertical pivot spindle positioned forward of the support axle. Two beams, each carrying two carrying wheels, are connected to the support at opposite sides. At curves and turns of the trajectory of the tractor, all of the carrying wheels will pivot together with their beams and the support structure around the pivot spindle. The wheels will therefore be oriented together, without skidding, in the forward direction.
