Abstract: A method is provided for bearing a pitch or grip of a belt running between a pair of opposing faces of respective first and second sheave members of a power transmission device. The method includes moving the second sheave member axially in relation to the first sheave member by translating to the second sheave member, in a form of linear movement, rotation of a control rod disposed substantially at right angles to a line of axial spoke of the second sheave member.

Abstract: An anti-wrapping device is described for preventing crop from being wrapped about the central shaft of a reel rotatably supported on side arms of a header of a combine. The device comprises an annular cover plate for securing to the axial end of the reel to prevent the crop from becoming entangled with projections from the reel and a tubular shroud for mounting on the header support arm to surround the central shaft of the reel, the axial end of the shroud being positioned when in use in close proximity to the annular cover plate of the reel to avoid any crop being caught therebetween.

Abstract: A drive mechanism for utility machinery is disclosed. The mechanism includes a driver wheel and a driven wheel that are coupled by means of an endless flexible band trained around outer rims of the driver and driven wheels. The driver wheel is adapted to transmit drive to the driven wheel in a forward direction F along a loaded side of the band. The mechanism further comprises an idler wheel that runs on an outer side of the band and applies an inwardly directed tensioning force to the band on a run of the band that is unloaded when forward drive is being transmitted. A reverse driver is positioned between the idler wheel and the driven wheel on an inner portion of the side of the band that is unloaded during forward drive. The reverse driver is adapted to selectively provide a reverse drive to the band.

Abstract: The invention relates to a device for adjusting the width of a sieve opening on combine harvesters so as to permit a quick installation of a new sieve or a quick re-installation of the previously used sieve, whereby enabling the previous width of the sieve opening to be immediately readjusted. The lamellas of the sieve are adjusted by means of an adjusting rail, which is actuated by a transversal shaft and by an adjusting mechanism both of which being mounted in a positionally fixed manner on the sieve housing of the cleaning device. The transversal shaft, to which an upwardly oriented driver is attached, is located underneath the sieve, the driver being connected to the adjusting rail by means of positive locking that can be disengaged by an upward movement of the sieve.

Abstract: A grain tank of an agricultural harvester having a top formed with an opening is provided. A cover overlies the opening, and a lifting mechanism is provided for raising the cover to an elevated position. Side panels extend between the cover and the top of the grain tank when the cover is in the elevated position to provide an enclosed extension volume that increases the storage capacity of the grain tank. At least two of the side panels are rigidly and permanently connected to the cover.

Abstract: A crop chopper arrangement generally comprises a discharge apparatus having an inlet adapted to receive chopped crop from a crop chopper for an agricultural machine. The arrangement further includes a row of guide vanes positioned substantially transversely to a longitudinal axis of the agricultural machine and adapted to spread out a flow of the chopped crop from the discharge apparatus in a direction substantially rearwards to a direction of travel of the agricultural machine. One or more of the guide vanes has a shape or configuration that is adapted to impart a predetermined deviation to at least a portion of a flow of chopped crop passing through said discharge apparatus. The shape or configuration of each guide vane is dependent on its transverse position in the row. This arrangement makes it possible to realize an even distribution of the chopped crop over the full width of the harvester header.

Abstract: A concave arrangement is disclosed for a threshing machine such as a combine harvester 10. The arrangement includes a concave 30 having a moveable rear portion 48 that is adapted to vary the break-over angle presented to straw passing downstream. A flap member 54 is provided that moves jointly with the moveable rear portion 48 and ensures that a gap G between the moveable portion 48 and 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.

Abstract: The invention relates to a device for adjusting the width of a sieve opening on combine harvesters. The aim of the invention is to be able to economically produce this device and to permit a quick installation of a new sieve or a quick re-installation of the previously used sieve, whereby enabling the previous width of the sieve opening to be immediately readjusted. The invention also aims to be able, while using the device, to adjust the width of the sieve opening on a preliminary sieve from an easily accessible location. To these ends, the lamellas of the sieve are adjusted by means of an adjusting rail, which is actuated by a transversal shaft and by an adjusting mechanism both of which being mounted in a positionally fixed manner on the sieve housing of the cleaning device. The transversal shaft, to which an upwardly oriented driver is attached, is located underneath the sieve.

Abstract: An agricultural harvesting machine having a threshing and separating mechanism for threshing and separating crop material; and cleaning mechanisms for cleaning the threshed and separated crop material. The cleaning mechanism comprising: a grain pan for receiving threshed and separated crop material and transporting the latter rearwardly; and an upper and lower sieves installed behind the grain pan and operable to receive the material from the grain pan and move it through and along. At least one portion of the grain pan is inclined in a sideways direction for sideways movement of the threshed and separated crop material while it is being transported rearwardly towards the sieve. This inclination spreads out the surplus of crop material supplied to one longitudinal section of the grain pan and delivers it in an even pattern to the front section of the upper sieve.
