摘要： In an earth working apparatus (10, 12), a separate router bit (32) and support (34) are removably secured along a generally vertically extending side member (22) of an earth-working blade (18). By forming them of separate elements, the router bit can be made of inexpensive plate metal while the support can be economically forged since it is in relatively protected position between the router bit and side member. The support is reversible and has a first lip (36) overlying the upper end (38) of the router bit and a second lip (40) underlying the lower end (30) of the side member whereby forces are transmitted directly from the router bit to the side member through the support instead of through the removable bolts (50).

摘要： PCT No. PCT/US79/00090 Sec. 371 Date Feb. 15, 1979 Sec. 102(e) Date Feb. 15, 1979, PCT Filed Feb. 15, 1979, Ser. No. 30,244. A router bit assembly for an earth working apparatus (10, 12) including earth working means having a generally horizontally elongated blade (18) with a generally vertically extending side member (22) at at least one end of the blade, a relatively tall router bit (32) formed of plate metal extending along the side member and in proximity to the blade, a relatively short support (34) for the router bit interposed between the router bit and the side member and having a first lip (36) overlying and substantially abutting the upper extremity (38) of the router bit and a second lip (40) underlying the lower extremity (30) of the side member, and removable bolts (50) securing the router bit and the support to the side member.
