Gentle processing with ROC continuous mergers

The ROC company from Romagna (based in Camerano, near Rimini) has always been associated with the design and manufacture of continuous mergers, the RT models.

Compared to other haymaking technologies, our machines do not drag the crop across the ground, the manufacturer explains in a technical note, but load it onto a conveyor belt and then gently place it on the ground. The system offered by ROC is particularly beneficial because, in addition to ensuring maximum cleanliness of the forage, it also means less product loss and less damage to the regrowth. The extensive and diverse catalogue from the Emilia-based company includes various mergers, which differ from each other mainly in terms of working width.

The RT 730 is the mid-range model that sits between the compact RT 380 and the more sturdy RT 1150 (the top of the range is the RT 1200, which has a working width of 12 metres).

The RT 730 merger consists of two elements and has a variable width ranging from 5.9 m to 7.3 m thanks to a hydraulic double dipper system that allows the distance between the two pickups to be varied even while working. With the pickups attached, the ROC merger can unload the two belts on the right, left or both sides, while with the pickups extended, it can create a central swath, or on both sides, or a central and lateral swath.

The RT 870, on the other hand, consists of 3 elements, for a working width of 8.7 metres and a pickup width of 7.6 metres. This machine has the option of unloading the three belts from both sides, or two belts from one side and one from the other, and the belt of the central element can be pulled out to form a central swath after the crop has been completely lifted. With the RT 870 it is possible to make two, three or four passes, taking up the previously formed swath without any reduction in product quality, and to put together four swaths. This model can also form deposited swaths over an area where the crop has already been harvested, for example by directing two of the three belts in one direction and the third in the opposite direction. The power requirement from the tractor is 90 horsepower.

The RT 1000 is one of ROC's high-end mergers. Its three elements achieve a working width of 10 metres and a pickup width of 8.8 metres. The RT 1000 is equipped with a suspension system on each element and on the machine itself, and can unload all belts on the right, or on the left, or two on one side and one on the other. It has a power requirement of 100 horsepower and is capable of forming a swath every ten metres, resulting in a significant reduction in fuel consumption.

The RT 100 can also make a single swath every 40 metres. All ROC mergers are road-compatible, and most models sold in Italy can circulate with a width of 2.5 metres.
