The Groutzilla system from Stone Construction Equipment can now be powered either via a PTO or a 13-horsepower Honda gasoline engine. Groutzilla is designed to simplify the placement of grout in blocks, walls, forms and foundations. Working in concert with a telehandler or large forklift, says Stone, Groutzilla’s mechanical delivery system can handle material of almost any slump to fill multiple courses of block spanning 20 feet or more.The Groutzilla system from Stone Construction Equipment can now be powered either via a PTO or a 13-horsepower Honda gasoline engine.
