kubota diesel engine. running on red diesel, there are 6 places withing 10 miles of my front door that will fix a Kubuta, don't use a Yanmar or Lombardini these are good engines but not alot of companies available to fix them
cat 45 pump with a direct feed bypassing the heat exchanger so you can pressure wash without the water having to pass through th Heat exchanger, this will allow you to have the full power & flow of the pump (Hx coils are too narrow they restrict flow)
a small diesel hotbox to heat the water rather than a heat exchanger- instant very hot water and again 4 companies within 10miles of me who can instantly fix them.
a large filter system that allow the waste water to pass through the blower ( as per the prowler) so no waste tank needed.
engine & blower joined with a fenner flexible coupling that is
5 times larger than needed so a 20hp engine has a coupling that will handle 100hp- it will last for ever and never needs changing.
no chemical injection,( they never work right) just fill your fresh tank with the pre-mixed solution.
mounted on a frame with forklift lifting points.
