The seed openers with the sealed bearing provides longer life in dirty conditions. A sized or worn bearing will cause irregular rotation resulting in an irregular seed furrow. Seed tubes with infrared sensors give you the best rate counts in high-volume soybeans, sorghum and sugarbeans.
Seed tube guard prevents opener blades from contacting seed tube sides and reduces soil buildup on the blades. The gauge wheel arm is mounted to and pivots on a spindle on the shank.
when this spindle or arm becomes loose and the gauge wheel cannot be properly positioned next to the opener blades. Replacement of the arm and bushing will correct this problem without the need to replace the entire shank. Be sure to properly position the gauge wheel against opener blade assemblies. The gauge wheel bearing operate in very dusty conditions. check bearings frequently and replace if they do not rotate easily.
