8. RPM II Design Front Ring moved rearward: Less Weight provides larger capacity without increased weight RPMII vs. Conventional Lower Trunnion for better control and dumping

10. Reverse Spade Lip As bucket engages the cut, the rear of bucket lifts slightly, pulling the center teeth out of the material. With the force concentrated on the corner teeth, there is less resistance and bucket penetrates better.

11. RPMII Features Cast Front End Ring for structural integrity, low maintenance Integral Trunnion cradles bucket, resulting in faster, cleaner dumping Reverse Spade Lip penetrates easier, resulting in faster fill S130 or S145 Reverse Spade Lip with S130H112K Adapters and 112K Series Points with S145H122K Adapter and 122K Series Points Stiffener plates reinforce casting-to-plate transitions
