Hydra-II Multi-Coupler: One Coupler. More Work.

Contractors, dealers, and rental houses are all facing the same challenge. Mixed fleets are becoming the norm, but attachments are still locked into brand‑specific interfaces. Every time a new wheel loader enters the fleet, someone must decide whether to convert attachments, buy duplicates, or limit which machines can run which tools. All of those options cost time and money.

The TAG Hydra‑II solves that problem. It is a multi‑coupler system engineered to let wheel loaders pick up attachments across the most common industry interfaces. With the Hydra‑II, your fleet becomes more flexible, your attachments become more valuable, and your operators gain the freedom to run the tools they need without worrying about compatibility.

Two Models. One Purpose. Total Compatibility.

The Hydra‑II is available in two sizes that cover the most widely used wheel loader attachment interfaces in North America. 

• Hydra‑II 200–500 Class – Picks up JRB 416 and John Deere Hi‑Vis or Volvo L50 through L120 ISO. 
• Hydra‑II 600 Class – Picks up JRB 418 and John Deere Hi‑Vis or Volvo L50 through L120 ISO. 

Both models are built to the same TAG standards for strength, durability, and precision fit. They are also fully customizable for all makes and models of wheel loaders, which means the Hydra‑II can be integrated into any fleet strategy. 

Why the Hydra‑II Matters for Contractors 

Modern contractors are running more diverse fleets than ever. Machines are coming from different manufacturers, different dealers, and different rental sources. The Hydra‑II gives contractors the freedom to: 

• Bring new machines into the fleet without converting attachments 
• Move attachments between machines regardless of brand 
• Reduce downtime caused by interface mismatches 
• Increase utilization of every attachment they own 
• Standardize their fleet around a single, proven multi‑coupler system 

The result is a fleet that works together instead of fighting itself. 

A Game-Changer for Dealers and Rental Companies

Dealers and rental houses need versatility. Every machine on the yard should be able to go out the door with the right attachment package. The Hydra‑II helps them:

• Build rental fleets that can support more customers with fewer attachments
• Improve machine utilization and shorten time‑to‑rent
• Offer customers a more flexible, more capable wheel loader package

A rental loader equipped with a Hydra‑II can support contractors running JRB, Deere Hi‑Vis, or Volvo ISO attachments. That versatility is a competitive advantage.

Built for Real Work

The Hydra‑II is engineered for the demands of heavy production work. Key design priorities include:

• High strength steel construction
• Precision machining for tight, repeatable fit
• Robust locking system for secure attachment retention
• Compatibility with OEM and aftermarket loader attachments and specialty tools
• Full support for OEM loader specifications

Every Hydra‑II is built to handle the torque, breakout forces, and duty cycles of modern wheel loaders.

A Smarter Way to Build a Fleet

The Hydra‑II is more than a coupler. It is a fleet strategy. It gives contractors, dealers, and rental companies the ability to run mixed fleets without mixed headaches. It protects attachment investments. It increases machine versatility. It simplifies operations.

If you are looking to make your wheel loader fleet more flexible and more profitable, the Hydra‑II is the solution.
