Chain, Teeth, and Sprockets
Chain and Tooth Maintenance
• Always replace sprockets at the same time as the digging chain. Sprockets and chain are designed to
work together. Replacing one without the other will cause premature wear of the new part.
• Keep digging chain sharp. Using dull, worn teeth will decrease production and increase shock load to
other trencher components. It can also cause chain stretch, which leads to premature wear and
failure.
• Maintain proper amount of tension on digging chain. Overtightening will cause chain stretch and loss
of machine performance. For correct tightening procedure, see “Maintenance” on page 143.
• Use tooth pattern most appropriate for digging conditions. If conditions change, contact your
Ditch Witch® dealer for information about the most effective chain type and tooth pattern.
