Amazone has reworked the front end of its Teres 300 heavy-duty mounted plough so that it can work on-land as well as in-furrow, Farmers Weekly reports. The change means the five/six-furrow reversible can be pulled by high-power tracked and wheeled tractors on oversize tyres as well as by smaller tractors whose tyres fit in the furrow.
Running on-land keeps the tractor's wheels or tracks off the furrow bottom, which matters for heavy machines on wide tyres. On the Teres 300 Onland the plough is switched between modes hydraulically from the cab through the parallelogram links and cylinder, and Amazone's AutoAdapt mechanism adjusts the front furrow width so that each bout matches the last.
The plough is built for tractors of up to 300hp. Its main beam is 150mm square, made from 8.8mm steel, and the headstock has a bearing-mounted cross-shaft with integrated balls for hitching to the lower links. Base models have manual furrow-width adjustment; "V" versions and the Onland model have hydraulic settings, with ranges of 30-50cm (12-20in) or 33-55cm (13-22in).
Amazone says there is enough clearance to turn the plough over without first pulling it in, even at wide settings. Only the beam swivel cylinder works during turnover, which the company says means less pivot wear than on a plough that must be pulled in and pushed out at every headland.
The Onland version also uses Amazone's SpeedBlade body, where most wear is taken by a patented extra-large front shin, so that the mouldboard, whole or slatted, should last longer at fast working speeds. Buyers can choose mechanical or hydraulic break-back protection.
