The furrow pressIt is important to retain soil moisture, especially when ploughing in dry conditions during the autumn. Rolling as soon as possible after ploughing is one solution to this problem. The furrow press, a narrow version of a Cambridge roll with one or two sets of widely spaced rings, is an alternative method of consolidating freshly ploughed land. A furrow press can be attached to a plough or a hydraulic linkage in front of the tractor. Rear presses are pulled from a special drawbar bolted to the plough. Working widths which vary from about 1-3 m are suitable for three- to seven-furrow ploughs, and the width of some models can be increased or decreased to a certain extent. Furrow presses can be used with an even larger plough by attaching two or three units at intervals along the frame. Trailed furrow presses either have a three-point linkage hitch for transport purposes or can be lifted above the plough with a hydraulic ram and carried in that position. In operation, a rear-attached furrow press is automatically detached when the plough is lifted at the headland. The furrow press has a double pick-up arm which provides a method of connecting it to a reversible plough in both directions of travel. After turning on the headland, the plough is lowered into work and a towing hook on the plough engages with the furrow press pick-up arm. Care is needed when lowering the plough to ensure that the press is coupled successfully. Furrow presses can also be used on a front linkage or suspended from a heavy duty arm which pivots on a frame attached to the front of the tractor (Fig. 30). Front-mounted furrow presses - some have an automatic steering mechanism - are often used in conjunction with rear-mounted power harrow and drill combinations. The arm-mounted front press is moved from the left- or right-hand side of the tractor with a hydraulic ram and is held centrally in front of the tractor for transport purposes.
Plate 30. A hydraulic ram swings this front-mounted furrow press across to the other side of the tractor when it returns across the field.
