We are using a Gil CHM-15B plough with our Agrotron 85 this time. It is with size arm of 30x30 mm, in two lines and interrows distance of 26 cm, frame size of 80x80 cm and working width is about 390 cm. Multipurpose cultivator works perfectly in fine labor and 25cm depth working.
We have hydraulic markers set on our plough. We don't want to have overlaps to save time and diesel. They are very easy and working with them is very confortable. We can do straight rows.
