Caterpillar D8R fitted with Single shank ripper and 8SU blade. Hydraulic hoses depicted on ripper and blade. This is a model I built as the standard D8R model does not have a single shank ripper or a 8SU blade. I have never seen another model like this, the 8SU blade really sets this model off. The price reflects the cost of buying a D8T to get the blade, I'll leave that one with you
