Diesel Deaf, You should not you think that Reba's spec was max width, in other words a D3 which has a 10' blade? Years back I hauled a TD24 (at the least regarding the size of a Cat D8) and it had been about ten' track width.We also supply choices for numerous Caterpillar diesel engine models, which includes Cat C15 6NZ, C10, C12, C13, 3406E, 3406B
