Optional Attachments
LT-Series Hydraulic Excavator capabilities have expanded far beyond excavation tasks with buckets. With the advent of hydraulic-powered attachments such as a breaker, a grapple or an auger, our excavator is frequently used in many applications other than excavation. Our excavators feature a quick coupler for simplified attachment mounting, increasing the machine's utilization on the job site.
