My local Home Improvement store has a John Deere cold water , two wheel, 4gpm, 3800psi ,Heavy Duty,Proffessional grade triplex pump,Honda GX390 engine.this is on clearance for $700. direct drive. I do understand belt drive is better.This unit would be used for housewashing and cold water flat work. Just for starters. Just looking to cut start up cost if possible.Thanks
