The furrower is an agricultural machine suspended from a tractor’s three-point linkage (TPL), used for mechanically covering of silage heaps and storage mounds with soil.
The main element in the machine is a steel plate, which is rotated by the power take-off (PTO) shaft. On the plate there are four knives (they cut the earth and grass) and four blades (they throw earth onto the mound). Thanks to the cutting knives, the machine does not clog up or throw clods that that could perforate the film. The working depth is adjusted by means of a hydraulic jack. The furrower has the facility to determine the height of the soil ejection by means of an adjustable cover.
With the furrower, covering takes 15 to 30 minutes depending on the size and length of the mounds/heaps. The machine easily handles heaps as high as 3 m and as wide as 24 m.
The VARIIS hiller is a reinforced version of the machine. The blades in the spreading disc are made of a double flat bar. The VARIIS model uses steel bearing housings.
