Common Use Case or Symptoms:

Use when the ripper tip is worn blunt, has lost its penetration profile, or has broken off the shank on a Cat D6R, D7R or 16H.

Why Choose Broken Tractor:

• ✅ Right tip for the R350 shank — We name the R450 and R500 tips so a D8 or D10 owner does not order the small one.
• ✅ Pin and retainer numbers listed — Tip, pin and retainer in one order.
• ✅ 39 machines on one tip — D5 through D7 dozers, 16-series graders and the 446D/450E backhoe ripper.
