Hi all. I currently have a hurcules 2 and it is in red. From what i have been told the hercules 1 has a 2 cylinder kubota engine, 2 piston cat pump and a small roots blower not sure on model no. Hercules 2 that i am running has a 3 cylinder kubota engine, 3 piston cat pump and a 5 series blower(roots). I am building up a second van and would really like another one. Cheers for reply's Jon.
