The tined harrow hydraulic “rainbow” is designed for stubble breaking and seedbed preparation, soil loosening and levelling of the field surface, moisture closing and destruction of weed germination, breaking lumps of soil and also for harrowing of sprouts of cereal and technical crops. A typical range presents a very practical, mobile, and affordable in its segment mounted and trailed hydraulic coupling of the boron Zigzag width from 15 m to 21 m for tractors from 130 HP to 350 HP With hydraulics, without human intervention, the harrow is folded in its working position, as well as going in a transport. In case of clogging of one or two rows of harrows stubble remains, the operator automatically, by means of hydraulics can produce their cleaning, by lifting the coupler and the exit from crop residues.
