I have a Red Rock stump grinder YTL 003-420 , serial SP48N03021060046. Can you provide instructions and photo on how to replace the cutting teeth please . The manual does not provide enough detail. Thank you
Lefty-loosy-righty-tighty is a good place to start. Remove bolts and nuts. Replace tooth. Re-fasten nuts and bolts to the specified torque. Are you asking for instructions on how to use a wrench?
