Quick Hitch, Mechanical & Hydraulic Versions

Excavator Couplers

TRUE Attachments has excavator couplers to meet almost any dealer or rental fleet need. We offer two main types: pin-grabber style couplers, which work with traditional pin-on attachments, and quick-hitch couplers, which work with specialized hook-and-pin attachments (popularized by Wain-Roy). Pin-grabbing couplers come in mechanical or hydraulic varieties.
