         6 . The bracket of  claim 1 , wherein the rear arched wall extends around a first axis, the front arched wall extends around a second axis, and the at least one central wall is an arched wall that extends around a third axis, and wherein a straight line joins the first axis, the second axis and the third axis. 
     
     
         7 . The bracket of  claim 1 , wherein the rear arched wall extend around a first axis, the front arched wall extends around a second axis, and the at least one central wall is an arched wall that extends around a third axis, and wherein the third axis is distant to a straight line joining the first axis to the second axis of at most 20% of a distance between the first axis and the second axis. 
     
     
         8 . The bracket of  claim 1 , wherein the bracket comprises locking enclosures neighboring the front room and the rear room in-between the mounting edge, each one of the locking enclosures having an opening facing away to a most-distant one among the frontmost location and the rearmost location, each one of the locking enclosures comprising a wall section about its neighboring room adapted to be abutted by a blocking bar of the coupler, wherein, when a locking enclosure and its neighboring room are housing one of the mounting disks and the blocking bar, the bracket is gripped in-between. 
     
     
         9 . The bracket of  claim 1 , wherein the abutting members have a cylindrical shape, and the at least one central wall comprises at least one central arched wall. 
     
     
         10 . The bracket of  claim 1 , wherein the at least one central arched wall consists in a single central arched wall. 
     
     
         11 . The bracket of  claim 1 , wherein the central arched wall extends over 120 degrees. 
     
     
         12 . The bracket of  claim 1 , wherein the at least one central arched wall comprises two central arched walls. 
     
     
         13 . The bracket of  claim 1 , wherein each one of the two central arched walls extends over 120 degrees. 
     
     
         14 . The bracket of  claim 1 , wherein the at least one central room comprises two central rooms, the body further comprising a lug extending between the two central rooms, the lug extending away to the mounting edge. 
     
     
         15 . The bracket of  claim 1 , wherein the abutting members have a non-cylindrical shape. 
     
     
         16 . The bracket of  claim 1 , wherein the at least one central room comprises a front wall section, a bottom wall section and a rear wall section, a front join where the front wall section adjoins the bottom wall section, a rear join where the rear wall section joins the bottom wall section, wherein the bottom wall section is a non- straight wall section comprises an apex extending away from the mounting edge beyond a plane extending between the front join and the rear join. 
     
     
         17 . A kit for an excavator having an articulated arm, the kit comprising:
 a coupler adapted to mount to the articulated arm, the coupler comprising a first shaft with mounting disks secured thereto and a second shaft with abutting members mounted thereto;   an excavator bucket assembly comprising a bucket and brackets secured thereto, the brackets extending parallel to one another, each of the brackets comprising:
 a body extending along a first plane between a frontmost position and a rearmost position, the body comprising a mounting edge adjoining the bracket to the bucket; 
 a rear recess located about the rearmost position, the rear recess comprising an arched rear wall defining a rear room, a rear opening providing access to the rear room, the rear opening being oriented substantially away from the frontmost position; 
 a front recess located about the frontmost position, the front recess comprising an arched front wall defining a front room, a front opening providing access to the front room, the front opening being oriented substantially away from the rearmost position; and 
 a central recess comprising at least one central wall each defining a central room, each of the least one central wall having a central opening oriented substantially away the mounting edge, 
   wherein the brackets are adapted for any of the front room and the rear room to receive one of the mounting disks of the coupler, and for at least one of the at least one central room to receive one of the abutting members of the coupler whereby mounting the bucket to the coupler either frontwards or rearwards.   
     
     
         18 . The kit of  claim 17 , wherein the coupler comprises a dispositive to lock coupling between the coupler and the brackets. 
     
     
         19 . The kit of  claim 18 , wherein the dispositive is a safety pin. 
     
     
         20 . The kit of  claim 17 , wherein mounting the brackets to the coupler requires to insert the disks into two of the non-central recesses before inserting the abutting components in some of the central recesses.
