Seeding unit
A seeding unit is a working assembly of a planter or air seeder designed to open a furrow, place seeds at a precise depth, and cover them with soil.

The seeding unit is the primary component determining seed placement accuracy. It typically integrates a furrow opener, depth control gauge wheels, and a packing mechanism to ensure optimal seed-to-soil contact.
Operators must adjust the downforce based on soil moisture and texture to prevent furrow compaction or inconsistent depth. Routine maintenance, such as checking disc wear and spring tension, is essential to maintain uniform emergence across the field.
Common operational mistakes include improper depth settings, which delay germination, or insufficient pressure that leaves seeds exposed. Keeping seed tubes clear of debris is vital to prevent skip errors during high-speed planting.
