  • Patent number: 6915736
    Abstract: A baler is described which has a collection chamber or duct and a baling chamber. Crop material enters the duct until a pre-determined level has been reached at which time a stuffer transfers the pre-compressed crop to the baling chamber. A control system is provided for calculating the ratio between the amount of crop material which should be formed into bales under optimal conditions and the rate of flow of crop material entering the duct. This ratio can be displayed and used to control the speed of the towing vehicle. The present invention uses the duct as a kind of measuring cylinder to determine the rate at which crop material is entering the baler.

  • Patent number: 6026741
    Abstract: An agricultural baler having a baling chamber and apparatus for loading successive charges of crop material into the chamber. The cross section of the baling chamber is automatically adjusted to the load experienced by the plunger during compression of these charges and thereby controlling the density of the bales formed therein. The density control system further comprises elements associated with the actuator of the baling chamber for precluding adjustment of the cross section when no new charge of crop material has been introduced into the baling chamber. These elements comprise a sensor sensing the passage of such charge along a wall portion of the baling chamber and a by-pass valve which controls the pressure of hydraulic oil provided to the actuator. Thus the cross section of the baling chamber is prevented from being reduced further when the baler is turned on headlands.

  • Patent number: 5489029
    Abstract: An adjustable sieve mechanism for an agricultural harvesting machine comprising louvres positioned behind one another and being movable through a range of positions between a fully closed and a fully opened position. Consecutive louvres define an opening when in an opened position. An adjustment mechanism is provided for changing the opening. Also provided is an opening indicator including a movable part which is unitarily moved with one of the louvres when the opening is adjusted. The indicator permits verification of the sieve opening even when the louvres are not accessible for measurement with gauges, and a direct link between the louvres and the movable part avoids the inaccuracies which are conceivable when the indicator is sensing the movement of further, intermediate components of the adjustment mechanism.
