A concrete extruder attachment for a vehicle includes a hopper adapted to hold flowable concrete. The hopper has an upper concrete inlet and a lower concrete outlet. A slip form is connected to the lower concrete outlet. An internal vibrator causes concrete to flow from the hopper through the lower concrete outlet to the form. A mounting is provided which is adapted to mount to a vehicle. A hopper support is secured to the hopper. The hopper support is pivotally mounted to the mounting for pivotal movement between a first position with the hopper extending toward a first side of the vehicle and a second position with the hopper extending toward a second side of the vehicle. The support is selectively locked in one of the first position or the second position. The ability to pivot the hopper enables the concrete extruder to access corners.
