The loader should have at least 20 gallons per minute hydraulic flow. It is a plus for the loader to have a high flow hydraulic circuit generating 30 gallons per minute flow and it needs 3000 to 4500 PSI with the ability to lift 2500 pounds or more. Your skid loader should have between 75 and 95 hp or more.  It will need to be equipped with the universal mounting system that almost all loaders have and your skid loader will need to have an auxiliary hydraulic circuit with flat-faced hydraulic fittings as shown, these are the most common type fittings. Check to see if your skid steer loader is compatible.
