20100293915 | Articulating Hay Rake - The present invention relates to an economical wheel rake having two arms that adjust from transport position to an operating position using a combination of an actuator and a dual axis articulating joint. The hay rake apparatus having a wheeled frame, a rake arm having a trailing end and a leading end, an intermediate arm having a first end connected to the frame and a second end which is fixed to the rake arm, a dual axis articulating joint connecting the frame to the intermediate arm, a telescoping actuator attached to the wheel frame using a first actuator joint and to the intermediate arm using a second actuator joint. The dual axis articulating joint is pivotable on a horizontal and a vertical axis when the telescoping actuator extends or retracts causing a longitudinal and a latitudinal angle between the intermediate arm and the frame to change. The rake arm and rake wheels are therefore moveable from an inoperable transport position to an operable position. | 11-25-2010 |

20110088366 | ROTARY RAKING OR SWEEPING IMPLEMENT - The present invention provides an improved raking or sweeping implement such as a yard and trail rake that is configured to be pulled by an all-terrain vehicle (ATV), lawn mower, or the like. Rake can include a frame portion connected to a rotary portion. Frame portion can include an attachment mechanism for attachment to a pulling mechanism, such as an ATV. Rotary portion can include a drive shaft, a plurality of rotary shafts with raking tines, and a planetary gear system for driving the rotary shafts as the rotary portion is rotated. Rotary portion can be rotated by engaging a tire of frame portion with a drive mechanism connected to drive shaft such that rotation of the tire caused by pulling the rake causes the rotary portion to rotate. As rotary portion rotates, planetary gear system causes raking tines to rotate forwardly, raking up debris. | 04-21-2011 |
20120036820 | Center Splitter for Rake - 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. | 02-16-2012 |
20120117935 | ADJUSTABLE RAKE FOR FEED MATERIAL WITH MULTIPLE WIDTH ADJUSTMENT - An adjustable rake for raking agricultural products includes a wheeled cart configured to be pulled in a direction of travel on a surface of travel and first and second rake arm positioners coupled to the wheeled cart and configured to translate in a direction transverse to the direction of travel of the wheeled cart. First and second front rake arm assemblies are pivotably coupled to the first and second rake arm positioners, respectively. First and second inner rear supports are included, and each of the first and second inner rear supports is pivotably coupled to the wheeled cart and is configured to pivot as a result of translation of the first and second rake arm positioners in the direction transverse to the direction of travel of the wheeled cart. The rake may include optional splitter wheels. | 05-17-2012 |
20120247079 | RAKE WITH SHIFTABLE CROSS MEMBER - The present invention is a rake, comprising a tongue assembly and a wheel assembly operably coupled to the tongue assembly and being rotationally shiftable relative to the tongue assembly and the wheel assembly mounting a pair of rake assemblies. Each of the pair of rake assemblies is disposable in a generally horizontal disposition when the rake is in a transport disposition, the generally horizontal disposition being effected in part by the rotational shifting of the wheel assembly when transitioning between a working disposition and the transport disposition. The present invention is further a method of disposing the aforementioned rake in the transport disposition. | 10-04-2012 |

20100024375 | Front Mounted Rotary Hay Rake - A rotary type rake having a plurality of finger wheel rotary raking elements mounted on a frame and movable thereon from one to the other of a raking position to rake material on the ground into a windrow and a retracted raised traveling position. The frame is partly supported by a pair of caster wheel assemblies that are disposed in spaced apart relation with respect to one another and a distal end of the frame which connects securely to a front end loader mounted on a tractor. Oscillatory movement of the caster wheel assemblies is restrained by a brake acting on the shaft of the caster wheel assembly by which it is mounted on the frame. | 02-04-2010 |
20100251686 | HAY RAKE WITH FOLDABLE HAY RAKE ARM - 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. | 10-07-2010 |
20120031065 | Agricultural Machine to Rake Agricultural Products - An agricultural machine to rake a mass of hay, or other agricultural product, including at least a trailer-mounted frame, and an arm on which a plurality of operating tools are rotatably mounted. 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. | 02-09-2012 |

20130025251 | DEVICE FOR DISPLACING MOWN CROP - A mobile rake device for displacing mown crop has a frame with a rake tool assembly that has a path-shaped working range and includes two rake tools with rake tines. In an operative position, the rake tools are arranged behind each other in a staggered manner in the direction of travel to provide two path parallel sections to achieve the path-shaped working range. The rake tools displace the mown crop located in the path section to one side in a flow of crop in order to form ultimately one final windrow. The rake tool assembly has an auxiliary displacing tool, that is arranged to throw the crop, which has been collected by the first rake tool in a flow of crop or in the form of a windrow, a pre-windrow, across the front of the next rake tool towards the final windrow to be formed. | 01-31-2013 |

The crop processing tool can be a crop displacing tool, such as a rake. The crop processing tool is mounted on a first pivot arm which, in the region of a first pivot arm connection, is pivotably connected, about a substantially horizontal centre line, to the first side arm for movement between an operative position and a transport position. In the operative position, the first pivot arm connection is located at a larger distance from the main beam than the rotor centre line of the first crop processing tool. | 05-16-2013 |
