Skid Steer Auxiliary Hydraulics & Couplers

An integral part of the skid steer system is the external hydraulic system. This system is what powers the attachments that require hydraulic flow and can run anything from a snow blade to a brush mower. Hydraulic systems vary greatly depending on machine. Thankfully most machines use a similar set up, so compatibility is usually not a problem. Some of our attachments do require a certain amount of flow to operate.  Our web site has helpful information regarding flow compatibility.

First let’s talk about basic standard flow hydraulics. Varying from 8 to 23 gallons per minute depending on the machine, standard flow hydraulics will run most attachments and are included on virtually every machine made. Most use a flat faced coupler system that fits to our standard factory installed couplers.  If in the rare instance your machine has dimple style Pioneer or flat faced Parker couplers, please contact us for fitment.

High flow hydraulics range from 20 to 45 gallons per minute.  The high flow range is usually an option that can be added at the time of purchase, but it can also be added later in the life of the machine. There are 2 types of high flow hydraulics… single and dual stage. Single stage high flow machines use the same lines and couplers as the standard flow, while dual stage high flow uses completely separate lines and has a different set of couplers for high flow on the outside of the machine. The single stage machine controls high flow with a switch in the cab while dual stage simply works by attaching the appropriate couplers.

Below is an example of a dual stage high flow hydraulic system with the attachment control system. If you have a dual stage system and want to run high flow, please let us know your make of machine to ensure we send you the proper couplers.

Here is a single stage system with high flow and the attachment control system. Notice how it only has one set of couplers.

The attachment control system is also an option on most machines and allows additional electric over hydraulic functions. Some attachments like the snowblower, for example, require a switch to divert hydraulic flow to additional cylinders for chute rotation and deflection. This is accomplished by using an electrical harness that runs from the attachment to your machine’s attachment control system electrical plug. If your machine is not equipped with the attachment control system, no worries! We offer a universal pistol grip (pictured below) that you simply bring into the cab with you to operate the additional functions.

The Case drain coupler is used on some, but not all high flow attachments to help lubricate the motor and keep the temperature down. If your machine has high flow but does not have a case drain, not a problem.  We can accommodate you on all of our high flow attachments.
