Mix and dispense concrete into your post holes with the Mobile Mud Hog skid steer mixer! This skid steer attachment allows you to mix your own concrete with the rubber paddle mixer blades. You can also dump straight into the mixer from a concrete truck. 2 Way hydraulics allow you to get a proper mix. When you mix forward the side gate will open and allow concrete to pour out the side chute. When you hit reverse on your hydraulics it will close the gate and push the concrete back into the mixer.
