Abstract

An excavator bucket and attachment coupling system, consisting of a hitch body 4 which is locked onto the bucket or accessory 5. This is carried out by means of the locking of a section 3 and the end plate 7 against and between the tubular chassis section of the bucket 1, and the locking plate 6. Two locking pins 9 are powered through the two holes in the locking plate 6 to lock the hitch body to the bucket. Subsequent different buckets can be easily fitted to the same excavator by unlocking the hitch from the bucket and then locking the hitch on to the new bucket. A pin 14 is inserted to prevent the locking pins 9 from being inadvertently removed. <IMAGE>
