About Patriot Couplers

Patriot Attachments are our newest line of loader tools designed to give you the best price and fastest turnaround. We build & stock several Patriot Couplers at a time, which lowers our cost; and we pass the savings and fast turnaround to you. Patriot Couplers are fully compatible with your attachments configured for JRB 416 or 418 couplers.

Easily exchange attachments among all major OEM brands of 3-arm and 4-arm loaders.

One loader, many tools

While you can order all of your new attachments to work as a kit with the Patriot Coupler, we realize that you can’t just throw away the non-compatible attachments you already own. That’s why we designed adapters that are both easily installed on the rear of your existing attachments and rugged enough to keep your tool arsenal fully productive.

Features

A third function jumper hose kit is required to connect the existing third function loader lines on your wheel loader to the adjustable stops of the coupler.
