When multi-tasking is a must, the AMI Attachments Jawbone 4-in-1 Excavator Bucket responds with a multi-purpose design that digs, grades, grips and clamshells. At first glance, the AMI Jawbone excavator bucket looks no different than a regular digging bucket, however inside the crossbar is a powerful hydraulic rotary actuator. This provides all the power of a hydraulic cylinder-style thumb but without custom installation. With as much holding power and gripping strength as a thumb, the AMI Jawbone 4-in-1 Excavator Bucket handles logs, rocks and scrap easily. You can also switch between digging and ditching with the ability of two different cutting edges on one bucket. Now you can dig and grade without costing you downtime changing buckets. For swampy material handling, the AMI Jawbone Excavator Bucket also works as a clamshell bucket for loading and dumping straight down.
