UPPER BRUSH
Upper brush holds seed in seed disc pocket in seed retention
area. Brush must apply enough pressure against seed in
seed disc pocket as disc rotates through seed retention area
to prevent seed from dropping out of disc pocket. A damaged
spot, excessive brush wear, or foreign material lodged in brush
may greatly reduce meter performance.
Replace upper brush at 50-160 hectares per row of use or
sooner if damage or excessive wear is found. Position upper
brush into inner perimeter of seed retention area. Make sure
base of brush is tight against bottom of meter housing. Install
brush retainer and three hex head screws. Tighten screws in
sequence shown in photo at right.
NOTE: Use GD11122 upper brush retainer for soybean and cotton discs. Use GD8237 upper brush retainer for
milo/grain sorghum discs.
LOWER BRUSH
Lower brush moves seed down seed loading slots to seed pockets, isolates seed in reservoir from entering seed tube,
and cleans seed loading slots. Estimated lower brush life expectancy is 100-325 hectares per row. Replace lower brush
if bristles are deformed or missing, or if there are cracks in brush retainer.
