bRUSH-TYPE SEED METER MAINTENANCE
Use clean, high quality seed. Damaged or cracked seed, hulls, or foreign materials can become lodged in upper brush
and greatly reduce meter accuracy. Remove seed disc daily and check for buildup of foreign material on seed disc,
particularly in seed loading slots. Clean disc by washing it with soap and water. Check for cracked seed, hulls, etc.
lodged between brush retainer and stainless steel wear band which can greatly reduce accuracy of the meter because
upper brush will not be able to retain seed in seed disc pocket. Thoroughly clean brush areas of meter housing.

SEED DISC WEAR
Most seed disc wear is found in the agitation groove area (area
between seed loading slots). Wear affects planting accuracy at
high RPM. Lay a straight edge across disc surface at agitation
groove area and measure gap between disc and straight
edge. If agitation groove areas are worn in excess of .030"
and accuracy starts to drop off at higher meter RPM, replace
seed disc. Estimated seed disc life expectancy under normal
operating conditions is approximately 200 acres per row.
Severe operating conditions such as dust, lack of lubrication or
abrasive seed coating could reduce seed disc life expectancy
to under 100 acres per row.

STAINLESS STEEL WEAR BAND
If wear band wears through or if meter is used without
wear band in place, meter housing may be damaged.
Stainless steel wear band protects meter housing from
wear and is .030" thick. Replace wear band when there is
approximately .020" of wear in primary wear area. Estimated
life expectancy of stainless steel wear band is 240-800 acres
