The conveying channel (28) comprises a base (30) comprising an upstream base part (43) and a downstream base part (44). The upstream base part (43) is pivotal adjacent its upstream end (45) about a transversely extending first pivot axis (57). The downstream base part (44) is pivotal about a second transversely extending second pivot axis (76) towards the downstream end (51) thereof. The downstream end (46) of the upstream base part (43) is supported on a pair of first resilient mounting members (59) and the upstream end (50) of the downstream base part (44) is supported on a pair of second resilient support members (85) through a pair of carrier arms (78) which are pivotal about a transversely extending carrier pivot axis (74).

A feeding system for feeding wrapping material (26) into a bale chamber (15) of a fixed chamber roller baler (1) for circumferentially wrapping a round bale therein whereby the wrapping material (26) is fed from a roll (25) thereof through primary feed and pinch rollers (30, 31). The wrapping material (26) is drawn from the roll (25) by the primary feed and pinch rollers (30, 31) through a tensioning system (50) comprising spaced apart parallel non-rotatable first and second tensioning shafts (51, 53) of circular transverse cross-section. The first tensioning shaft (51) is carried on a pair of carrier members (55) pivotal about a pivot axis (57) defined by the second tensioning shaft (53) for adjusting the degree of tension induced in the wrapping material by the tensioning system (50).

A roller baler (4) comprises a fixed part (10) and a rear door (12) both carrying a plurality of bale rotating rollers (17) which define a bale chamber (18). The rear door (12) is pivotally coupled to the fixed part (10) about an upper pivot axis (8). Double-acting hydraulic rams (25) operate the rear door (12) between a closed state defining the bale chamber (18) and an open state for discharge of a bale therefrom. Pressurised hydraulic fluid from a pressurised hydraulic fluid source (40) of a tractor (2) is supplied through a main three-state spool valve (42) of the tractor (2) to the rams (25) through first and second hydraulic circuits (50, 55).

When the main valve (42) is in a third state isolating the first and second hydraulic circuits (50, 55) from the pressurised hydraulic fluid source (40), hydraulic fluid is accommodated from the first hydraulic circuit (50) to a primary accumulator (69) of a pressure reducing circuit (68) through the primary valve (70) until the pressure in the first hydraulic circuit (50) is at a selected one of a plurality of selectable hydraulic pressures, so that the rams (25) urge the rear door (12) into the closed state at the selected hydraulic pressure to produce the bales to a corresponding selected bale density. The primary valve (70) is operated under the control of a microcontroller (64), and the selected hydraulic pressure is transmitted to the microcontroller (64) from a control console (65) located in the cab (3) of the tractor (2).
