Plow Blades
Blade Maintenance
• Keep cable guide wing bolts tight. Loose cable guide bolts will break due to plow vibration.
• Keep plow feed tube free of rock and debris so that material pulls freely though tube.
• Use a speed blade only for straight or gently curving installations. Do not use speed blades for
installations that require sharp turns.
• Use the plow blade most appropriate for the type of material being installed. Contact your Ditch Witch
dealer for information about the most effective blade for your jobsite conditions.
