Get Maximum Performance from Your Skid Steer Hydraulics.

The right Bobcat quick couplers​ are essential for a peak-performing skid steer hydraulic system. They ensure efficient, leak-free operation for your machine and all its attachments. For smooth performance and minimal downtime, remember these three keys:

Understand​ how your hydraulic system and couplers work together.
Maintain​ the system with high-quality, correct couplers.
Choose​ the proper couplings to run every attachment efficiently.

Quick Couplers Used For Powering Attachments

Bobcat Attachments: Unlock Your Skid Steer's Full Potential

The Bobcat skid steer's versatility comes from its extensive attachment lineup. With the right hydraulic system, you can power dozens of specialized tools to tackle any job. Key attachments include:

Buckets

Handle everything from dirt and grain to rocks and construction materials with various bucket types

Wood Chippers

Process branches and tree limbs into mulch efficiently

Excavators & Diggers

Dig trenches up to 48 inches deep, remove stumps, and handle odd-shaped materials

Concrete Tools

Mix, transport, and pour concrete faster than standalone equipment

Land Clearing Attachments

Grapples, forestry cutters, and mowers clear debris, cut vegetation, and maintain large areas

Material Handling

Pallet forks lift heavy loads with precision

Snow Removal

Blades and pushers clear driveways, sidewalks, and uneven surfaces

One Critical Connection:​ All Bobcat attachments rely on the right hydraulic quick couplers for efficient, leak-free operation. Understanding your hydraulic system and maintaining proper couplers is essential for peak equipment performance, no matter which attachments you use.

How the Bobcat Hydraulic Coupler System Works

The hydraulic coupling systems on skid steer utility vehicles are very similar across varying makes and models, making it easy to understand how Bobcat hydraulic quick couplers work and how to best replace them. While many hydraulic quick couplers may be compatible with various skid steer and Bobcat equipment, they are not all made the same. Choosing the right Bobcat quick coupler will provide effective, efficient, and leak-free hydraulic fluid control.

Many people want to know what to do with their hydraulic couplers, how to connect them, and what they are for. It is important to know how to connect your skid steer attachments, how quick couplers are set up on your machine and the function of the quick coupling options on the outside of your machine. You should see quick connect coupling options lined up vertically on the outside of your machine.
The first coupler at the bottom, is typically a flat faced female quick coupler which is the pressurized coupler on a Bobcat. The trigger switch from inside the cab sends flow to this pressurized coupler to power your attachment such as a mower, a bucket or another motorized attachment. When the hydraulic flow returns it comes back through the male coupler which is the third one up from the bottom. The male coupler then takes the pressure back into the Bobcat, through the filter system to get re-pumped back through this female pressure coupler.

So, the bottom coupler is the female pressurized coupler which powers all attachments, the third coupler up from the bottom is the male return coupler, and the coupler in between the two is the case drain, which is a 3/8 male flat face coupler. This very important quick coupler takes any excess pressure back to the return line and into the reservoir. This case drain coupler will protect the motor on your attachments from bursting any seals due to built-up pressure. The connection attachments at the top are 14 pin or 8 pin electrical connectors which allow the operator to control additional functions on attachments.
