MODEL 821

After many customers requested a machine capable of digging 9 feet, CADplans has developed the CADDigger Model 821. The machine is a completely new design, not just a scaled up version of a previous model. Model 821 uses heavier section materials throughout. Three-inch cylinders on the boom and boom extension deliver the power to dig at 9 feet. The 10 hp engine and 6-gallon per minute pump delivers the productivity you need from a larger machine. And CADplans has arranged for a supplier to offer a kit complete with all parts cut so you can put Model 821 together in as little as 50 hours.

The bucket has been designed to offer higher ripping power and simple no form, assemble and weld construction. This assures you are productive quickly.

Model 821 is easily converted from trailer to digging mode with a quick, no-tools switch of the wheels from one end of the machine to the other. After conversion, Model 821 moves itself around the work site using the bucket for motivation. In a “crab-like motion”, Model 821 has plenty of power to locate itself for work. The low maintenance design of Model 821 ensures that your productivity is high at a low cost to you.
