Abstract: A suspension system for fixed-frame, towed agricultural implements having at least one floating head. A hydraulic cylinder is used for both lift and suspension of the floating head. A hydraulic accumulator provides expansion room for hydraulic fluid to move in and out of the hydraulic cylinder during suspension.

Abstract: In a round baler, twin arms come together in the start position, on the side opposite the cut position, because that configuration ensures that two twines lie nearly on top of each other to secure the bale much better at that end than with a single twine. The “start position” refers to that position where the twine arms reverse direction, and change from a fast speed of travel used to move the twine arms across the bale width, to a slower, controlled speed that is adjustable to vary the spacing of the twines. The change in direction combined with bringing the twine arms together at the start position, ensures that loose twine ends are effectively restrained as the twines are applied.

Abstract: Large cylindrical bales of hay, straw, or other forage or fodder are usually wrapped with a filament-type product, typically twine, or a sheet-type product, typically netwrap material, after a bale has reached a predetermined size. A method and apparatus are disclosed that permits the bale to continue to form during part of the wrapping process. A delay occurs between the initiation of the wrapping step and the alarm for the operator to stop the forward movement of the baler. By inserting the wrap material to an entry throat of the baler, new crop material may be added to the bale while the leading edge of the wrap material travels around the bale. The operator is notified only when the feed of additional crop material needs to be stopped for the wrapping operation to conclude. The present invention is applicable to the use of sheet or filament wrapping materials for binding round bales.

Abstract: A harvesting machine with a main frame, a harvesting header having a first end and a second end and a suspension system operatively attached to the main frame for supporting the harvesting header from above, the harvesting header having a lowered position and a raised position. A suspension frame has a rocker arm operatively pivotally attached thereto along a first substantially horizontal axis, the rocker arm having an upper position and a lowermost position. A first link is operatively pivotally attached to the suspension frame along a second substantially horizontal axis and is operatively pivotally attached to the harvesting header at the other end thereof. A second link is operatively pivotally attached to the main frame along a third substantially horizontal axis and is operatively pivotally attached to the harvesting header at a fourth substantially horizontal axis, the second link being disposed substantially always parallel to the first link.
