A combine harvester having a sieve that is moveable by a sieve drive assembly to perform a reciprocating sieve movement having a sieving stroke and a sieve throwing angle, wherein the sieve drive assembly has: a rotary drive, having a rotatable output shaft, a transmission between the rotatable output shaft of the rotary drive and the sieve, which transmission comprises an eccentric device, at least one transmission element, a plurality of linkage pivots, a first non-adjustable transmission element which is pivotably connected to the eccentric device, wherein the first non-adjustable transmission element is further pivotably connected to the adjustable transmission element, which adjustable transmission element is further pivotably connected to the combine harvester chassis, and wherein the first non-adjustable transmission element is further pivotably connected to the sieve through at least one further non-adjustable transmission elements.

A sieve for a combine harvester that is moveable by a sieve drive assembly to perform a reciprocating sieve movement having a sieving stroke and a sieve throwing angle, wherein the sieve drive assembly has a rotary drive, having a rotatable output shaft, a transmission between the rotatable output shaft of the rotary drive and the sieve, an eccentric device, at least one transmission element, and a plurality of linkage pivots, wherein the eccentric device is an adjustable eccentric device in which the eccentricity is adjustable in order to adjust at least one of the sieving stroke and sieve throwing angle, the eccentric device comprising an input shaft, a flange, a gear, an output shaft, an annular gear, and an adjustment gear.

A power transmission device for utility machinery is disclosed, the device including:

Utility machinery and associated control arrangements

A power transmission device for utility machinery is disclosed, the device including: a) a sleeve supporting a first sheave member having a first face; b) a hub received through the sleeve and moveable axially in relation thereto, the hub supporting a second sheave member having a second face that opposes the first face such that the first and second faces define therebetween a groove adapted to receive a belt and relative axial movement between the sleeve and the hub being adapted to vary at least one of pitch diameter and grip imparted to the belt from the sheaves; and c) an actuator mechanism adapted, through control of relative axial displacement between the sleeve and the hub, to vary at least one of the pitch and grip, the actuator mechanism comprising a control rod disposed substantially perpendicularly to the line of action of the axial displacement and connected to the hub through a link mechanism, the control rod being adapted to rotate and the link mechanism being adapted to translate rotation of the control rod into linear movement for relative axial displacement of the hub.

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.

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.
