A closer look at various row units
Depending on the type of seed drill, you can choose between the following row units:
Standard row unit
Standard row units are suitable for sowing with a minimum row spacing of 12.5 cm. The press wheel is made of regular or stainless steel, depending on the soil type. You can opt for a standard coulter or a coulter with Widia wear plates for improved wear resistance. A spring controls the downforce to the unit. All the springs connect to the same bar, meaning any change to the bar’s position affects the downforce on all units at once. The depth is adjusted using a lever along the side. No additional tools are needed. The press wheel contains a large, maintenance-free bearing. The standard row unit can also be fitted with an optional scraper for improved furrow covering to achieve a level seedbed.
Row unit with cutting disc
The row unit with cutting disc is suitable for sowing with a minimum row spacing of 16.7 cm. The cutting disc is mounted in front and to the side of the coulter. This unique positioning ensures optimum effectiveness of the coulter with a single disc. The disc enables easier planting in soil that has been cultivated but still contains crop residues. The disc cuts through the trash ahead of the coulter, preventing it from accumulating. The cutting depth can be set independently of the seeding depth. The seeding depth is adjusted by means of a depth wheel behind the press wheel. The press wheel is made of regular or stainless steel depending on the soil type. A spring controls the downforce to the unit. All the springs connect to the same bar, meaning any change to the bar’s position affects the downforce on all units at once.
Parallelogram row unit
This type of row unit is suitable for crops with widely spaced rows. The unit’s suspension is shaped like a parallelogram, allowing it to follow the ground’s natural contours more closely. This ensures a more accurate seeding depth. The unit is fitted with a disc to cut through any trash ahead of the coulter, preventing accumulation. A rear closing wheel applies additional pressure.
Additional seed drill accessory: Applasol
Optionally, Herriau precision seeders can be fitted with an Applasol packer roller. A packer closes furrows more fully, preventing moisture from escaping. It also helps to level the field, simplifying the harvesting process. The packer is available in a fixed or hydraulic folding version. The advantage of the hydraulic version is that it limits overhang to the rear during road transport.
