Abstract
An earthmoving implement (10) has a sidewall member (12) and a cutting edge (14), and an adapter (26) is releasably secured thereto. The sidewall member (12) has a step (20), and the adapter (26) has a pair of outer and inner mounting portions (35, 36) defining a first slot (38) therebetween. The adapter (26) also has a bottom portion (40) connected to the outer mounting portion (35) and defining a second slot (42) with the inner mounting portion (36) so that the first slot (38) straddles the sidewall member (12) and the second slot (42) straddles the cutting edge (14). A projection (80) is defined on the adapter (26) forwardly of the first slot (38) for transmitting a portion of a working force on the adapter into the step (20), and a fastening device (28) releasably connects the adapter (26) to the implement (10) and transmits another portion of the working force into the sidewall member (12).
