The Morrison Spreader is ideal for all types of after-pour applications, such as hardeners, colorings, light reflective coatings, etc. This model works with powder-based materials and trap rock with aggregate up to 3/8" (9.5 mm) in size. Superior material control is achieved with our independently controlled flow rate and hopper travel speed. The spreader is easily assembled and can be configured to suit your needs. Powered by a Honda GX160.
