I have only found 1 of these to be sold in the US, I think it was EasyKleen. I don't remember the exact quote, just that it was out of my price range. I think $1600 to $1700. I have the same plan, meaning I want a singe Engine to maintain, and have a low end Pressure washer that suits my current needs. As part of beginning this project I have already acquired a New Pressure Washer Pump manufactured by Giant. It puts out 3500 PSI at 4GPM, the important issue from my perspective it that the shaft rotation speed to achieve that PSI/GPM is 1340RPM. I also have a new Right angle Gear Box with a 1 to 2.5 ratio (540 X 2.5 = 1350). It was to be used on a mower deck, but I have concern that it is not built to be driven Via a PTO and when I put a 17HP pto shaft to it the gears may not hold up to the strain. By the way the Pump shaft can be rotated to either side of the pump, so I think I can easily match it to the rotation of what ever PTO attachment I end up using. I do have a few LoveJoy couplers to mate the pump to the gearbox in a flexible sort of way. No experience with welding here so for the moment this project is tabled till at least winter, But I would like to hear what others are thinking.
