Trobrazni 12 inch VK

The Turan three-furrow plow, 12 inch, VK design, is the largest standard (non-reversible) plow in the documented Turan range, with 3 bottoms and the widest working width of 90 cm. Clearance is 70 cm, and spacing between bottoms is 75 cm, the same as the other VK models in the range. Working depth reaches 30 cm, the highest across the whole VK line, suited to deeper plowing of harder-to-work soil. Machine weight is 367 kg, the highest in the documented standard-plow range, reflecting the reinforced construction needed to carry three wider bottoms during deeper plowing. Operation requires a tractor of 50 to 90 HP, the highest across the VK models, in line with the largest working width and greatest working depth. Compared with the 10 inch three-furrow model (working width 75 cm, depth 25 cm, weight 318 kg, power 50-80 HP), this 12 inch model offers a wider width and greater plowing depth, with somewhat higher tractor power requirements at the top of the range. Accessories and spare parts for this model are not separately listed in the source document, unlike the two-furrow VK models. Thanks to the widest working width and greatest working depth in the standard (non-reversible) line, this model is intended for farms with the most powerful tractors and largest cultivated areas needing maximum productivity per pass without moving to a reversible plowing system. Unlike Turan's reversible (obrtač) plows, it has no bottom-flipping mechanism or hydraulics for turning, keeping construction simpler and more affordable at the cost of an open furrow between adjacent passes.
