2021 White Planters 9000 Series

A cast row unit assembly removes the flex/tolerances versus welded construction, providing strength and precise, consistent alignment of all components.

The large double disc seed trench openers (16-inch) allow for deeper seed placement.

The entry of seed at the lowest area of the seed sump allows gravity to assist in seed pickup and provides greater surface area to pick up seed, producing superior seed singling.

The long tapered entry to the air cut off brush gently lays the seed down for a consistent retention of the seed in each seed cell.

The depth adjustment handle provides adjustment and visual indication of planting depth along all row units in .25-inch increments. Each notch aligned left and right changes the depth .5-inch. Walking the handle one notch at a time, side to side, increases the depth .25-inch. Seed depth placement numbers are molded into the casting, providing a convenient visual indicator of the depth of seed placement for each row unit.

The gauge wheel depth adjustment mechanism contains a threaded bolt for the calibration of the seed planting depth as the seed trench disc openers wear and the diameter is reduced. The patented calibration system provides confidence the depth indicator is accurate through the entire depth range. Increased yields are experienced as the walking beam gauge wheels equalize the depth of the planted seed between the soil height on the left and right gauge wheel.

This design incorporates non-metallic composite bushings and shaft seals for maintenance-free performance. The seal reduces the ingestion of foreign material into the maintenance-free composite bushings. Extended operating time improves performance and reduces maintenance to increase the productivity of the planter.

An increased gauge wheel arm life can be expected in abusive planting conditions. No grease zerks are present in the gauge wheel arm pivot. The pivot bearings incorporate non-metallic composite bushings and shaft seals for maintenance-free performance. The gauge wheel arm depth stops are cast into the row unit for consistent range of motion between row units.

The heavy-duty cast hub (retainer) increases the retention of the bearing for greater durability. The double row ball bearing offers extended bearing life of the seed trench openers.
