Boss Agriculture Air Seeder

SX 25 Single Disc Units

Single Disc Row Unit

Today’s zero till or minimum tillage farming techniques are constantly pushing the boundaries of what seeding and planting equipment is required to perform. Most of the time conditions aren't perfect with either wet or borderline conditions to plant in. In developing our SX25 single disc planting row unit Boss Agriculture has tackled many of the challenges minimum tillage farmers face by developing a planting row unit which is effective for penetrating tight soils and is equally capable of planting into sticky conditions faced during winter sowing.

The combination of an offset and undercut disc opener allows the Boss SX25 single disc planting unit to dig effectively without requiring an over-engineered heavy frame to force the row units into the ground.

To tackle the wet sticky winter conditions where stubble becomes rope bound, a combination of a simplistic low profile seed boot, floating cleaning wheel and active mud scraper system has proven to be very effective in minimum tillage operations.
Boss Agricultures SX25 single disc row unit is manufactured at our factory and has been developed to provide Australian farmers with a local planting solution for minimum tillage or zero tillage planting conditions that we encounter.

The SX25 series of single disc row units from Boss Agriculture are available in 2 models with a spring or hydraulic ram used to control down pressure when seeding. Row units are easy to set up in the field and have simple pressure and depth adjustments. The unit requires minimal maintenance (1 grease nipple - 1 pump per 500ha) and has been designed with in-field service-ability in mind. All consumable parts take only minutes to service or replace keeping you in the paddock for longer. The seed boot delivers exceptional seed placement and is fabricated from hardwearing Bisalloy 500 material.
