摘要:
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.
摘要:
A suspension system for agricultural implements having at least one floating head using a four-bar linkage and permitting the floating head to accommodate variations in ground surface elevation in a lateral or transverse direction. By permitting the floating head to float, a more consistent cutting height is realized when ground surface elevation varies in a transverse direction. A main frame is provided to which the ground engaging wheels are attached. A sub-frame is connected to the main frame via the four-bar linkage. The sub-frame is pivotally attached to the arms of the four-bar linkage by spherical bearings.

Device for mowing crops, comprising a series of mowing units arranged side by side at predetermined distances, each mowing unit comprising a knife holder with at least one knife carrying portion for carrying a mowing knife, and a drive mechanism for each knife holder. The drive mechanism for each knife holder comprises a first drive element comprising a hub portion for carrying the respective knife holder, and a second drive element drivingly engaged with the first drive element to rotatingly drive the knife holder about a vertical axis. In normal operation, the knife holder and the hub portion form a unitary rotatable assembly which, at a position between the knife carrying portion and the hub portion, is provided with a break connection which is effective in a radial direction.

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.

摘要:
A drive system for agricultural implements having at least one floating head and a tongue that may be disposed at various angles relative to a longitudinal angle of the implement. Two swivel gearbox assemblies are used, each comprising a first 90° gearbox rigidly attached to the implement and a second 90° gearbox that is permitted to rotate about an axis passing through one of its shafts and one of the first 90° gearbox's shaft. Because the tongue angle is variable, the drive shafts for driving the implement must take on a plurality of angles. The swiveling gearbox assemblies allow variable angles at the tongue and at the header.
