Abstract
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). Hydraulic fluid is applied to the rams (25) through the first hydraulic circuit (50) for urging the rear door (12) from the open state to the closed state. 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).
