Chain, Teeth, and Sprockets

Chain and Tooth Maintenance

• Always replace sprockets at the same time you replace 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 teeth 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 chain wear and

failure.

• Maintain the proper amount of tension on the digging chain. Overtightening will cause chain stretch

and loss of machine performance. For correct tightening procedure, see page 82.

• Use the tooth pattern most appropriate for your digging conditions. If you move to a different soil type,

contact your Ditch Witch dealer for information about the most effective chain type and tooth pattern.
