With a rated penetration depth of 21 inches, the 3FR-21 combines an extra-thick AR400 steel ripping tine with AR400 side wear plates to provide a durable working tool for demanding ground conditions. It is intended for excavators rated from 6,000 to 10,000 lb operating weight and is suitable for breaking into frozen ground, working through difficult soil, and prying in rocky conditions. The mount must be specified for the excavator; a universal mount fit is not verified.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt for Frost and Rock\u003c\/h2\u003e\n\u003cp\u003eThe NM Attachments 3FR-21 frost ripper is engineered around a single, heavy-duty ripping tooth that concentrates excavator breakout force into a narrow working point. Its 21-inch penetration specification provides substantial reach into hard or frozen ground, while the extra-thick AR400 steel tine is designed for demanding ripping applications. AR400 side wear plates add protection to the attachment’s working structure in abrasive conditions.\u003c\/p\u003e\n\n\u003cp\u003eThe manufacturer identifies this product family for serious prying and ripping, particularly in frost or rock. This makes the 3FR-21 a practical attachment for excavation work where standard digging may be restricted by frozen or unusually resistant ground.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-tooth excavator frost ripper attachment\u003c\/li\u003e\n  \u003cli\u003e21-inch penetration depth\u003c\/li\u003e\n  \u003cli\u003eExtra-thick AR400 steel ripping tine\u003c\/li\u003e\n  \u003cli\u003eAR400 side wear plates for added wear protection\u003c\/li\u003e\n  \u003cli\u003eDesigned for serious prying and ripping in frost or rock\u003c\/li\u003e\n  \u003cli\u003eStandard CAT-style teeth configuration\u003c\/li\u003e\n  \u003cli\u003eVarious tooth options available\u003c\/li\u003e\n  \u003cli\u003eDesigned for excavators rated from 6,000 to 10,000 lb operating weight\u003c\/li\u003e\n  \u003cli\u003eMount must be specified to suit the excavator\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eExcavator Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe 3FR-21 is specified for excavators with an operating weight rating of 6,000–10,000 lb.
