A stuffer assembly includes a stuffer chute and a stuffer for transferring crop material from the stuffer chute into a baling chamber. The stuffer includes a tine bar having a plurality of tines. Each tine is slidably connected to the tine bar to be linearly movable with respect to the tine bar between an extended position and a retracted position parallel to a radial direction of the tine bar. A method accordingly includes retracting a tine from the extended position into the retracted position in case of an overload.

Stuffer assembly for an agricultural baler

An agricultural system including an agricultural baler and a control unit. The agricultural baler includes a pick-up arrangement for collecting plant matter. The pick-up arrangement includes a roller for feeding crop into the baler. The baler further includes a pick-up drive shaft for moving the roller at a desired rotational speed. The pick-up drive shaft is connected to the roller by a clutch for selectively transferring power between the pick-up drive shaft and the roller. The control unit is configured to: receive clutch-status-data indicative of an engagement status of the clutch; determine a speed-control-signal for varying the rotational speed of the pick-up drive shaft based on the clutch-status-data; and provide the speed-control-signal to a driveline for driving the pick-up drive shaft.

A concave arrangement is disclosed for a threshing machine such as a combine harvester. The arrangement includes a concavehaving a moveable rear portionthat is adapted to vary the break-over angle presented to straw passing downstream. A flap memberis provided that moves jointly with the moveable rear portionand ensures that a gap G between the moveable portionand a later processing stage such as a beater apparatus is kept substantially closed. Variation of the break-over angle influences the length of the straw leaving the threshing machine and the loading of the further separation and cleaning mechanisms.

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.

An agricultural baler comprises a frame, a pick-up assembly for picking up crop material from a field and a baling chamber for receiving crop material from the pick-up assembly, the baling chamber having at least one movable wall portion. A plunger is mounted for reciprocating movement in the baling chamber for compression of the crop material therein, the plunger being driven by a gearbox which is affixed to the frame. A control unit adjusts the position of the movable wall portion in response to the signal from a load sensor, which is connected by a lever to the plunger gearbox for monitoring the reaction forces of the crop material on the plunger during the compression stroke. The lever arrangement includes a longitudinal pull member connected to one arm of the lever and a ball bearing mounted over the load sensor and connected to the other arm of the lever for precluding the effects of transverse or upward vibrations of the gearbox on the sensor.

An agricultural implement, such as a baler comprises a main frame and a hitch for attachment of the implement to a towing vehicle. The frame is supported on a bogie comprising a pair of steerable wheels. A pair of hydraulic rams can block these wheels in a fore-and-aft position for reversing the baler or for preventing fluttering during road transport. Hydraulic circuitry, which is used for controlling functions of said implement, such as the retraction of a bale chuteor the operation of a bale eject apparatus can be used to actuate the rams. The rams are loaded by providing pressurized oil to the return line and using a non-return valve for making the oil flow to the guiding the said circuitry to the rams.
