I will definitely have to be extremely careful with it so I don't damage the hoe. I've read conflicting recommendations on how big a backhoe ripper tooth should be. Anywhere from around 16" to 29". Cat has a 25" listed for backhoes which is probably a good choice. Was reading it's best to keep the stick closer to vertical and use the bucket cylinder to curl the ripper rather than pull the ripper through the ground with the stick.
