I am posting for a fellow collector. Caterpillar D4600 six cylinder power unit w/radiator. Pony start. Was running an Ag well till taken out of service. Running condition, but hasn't run lately, with belt drive (maybe he said rockford type clutch). Owner did not want to scrap but wanted good home. Will this fit in a grader??Located in Merced, Ca.
