Cleaning Vacuum System Ducts

Dirt or the remains of chemical seed treatment may accumulate in the vacuum system ducts, causing the loss of vacuum in drills. This can lead to faults and subsequent lack of planting precision.

Clean the ducts at least once a week during planting season, or even more frequently if working in dusty conditions.

CAUTION: Agricultural chemicals may be hazardous. The inappropriate handling or choice of products can poison persons, animals and cause irreparable damage to the environment. Use and apply these products with care, carefully following the manufacturer's instructions.

To clean, proceed as follows:
