    Probably but my point was that the use of a belt to drive a pump is not uncommon. The advantage of a belt set up is that it's easy to change shaft speeds and get as close as possible to the correct speed of the pump without a big investment. I've never really looked into buying a pump but I have to believe that they are offered in multiple max RPM speeds. The slower speed pumps could be inexpensive or very pricey. Looking your link to Northern tool I'm guessing that the 3pt pumps are expensive since they are high gpm and pressures. After all of you have the torque of a tractor so why not get the most out of it.

    I have thought about mounting a 275 gallon IBC and a pressure washer on a small trailer for mobile use. I never really thought about using a PTO over an engine to power it but I'm thinking it would be a good idea. Once full the trailer would weigh over 2500 lbs, too much to be pulling up and down hills with a side by side safely, I would be using the tractor to pull it around. Since I'll have a PTO right there why not use it. The trailer tongue could be removable, a short one to work with the tractor and the correct length for the PTO shaft and a longer one so it could be pulled behind a truck.

    I spent some time last night looking and found no rpm stats for stand alone pressure heads. They all listed being bolted direct drive to modern engines. so rpm ranges of 1800-3600 rpm.

    They are positive displacement pumps so the faster you spin them the more flow rate they put out. In theory they should reach there max pressure relatively quickly as that is achieved by pushing the water through an orifice.

    Output side of this box is 1431 @ 540 input, so you'll want to find a PW pump that runs at 1450, that's a fairly standard speed for pumps that aren't "direct coupled" to an engine.

    Thanks for the link, that would be a good savings!

    So with the good price on the overgear mentioned above along with a 4000 PSI 4.GPM AR pump, unloader valve, hose and wand the total comes about $1000. My question at this point is whether the overgear (speeder unit that takes 540 PTO up to 1430 RPM) and pump can be direct mounted on the PTO shaft without any other visible means of support. Would require, of course, a torque arm or chain. Notice that the female 540 on the front of the overgear is split and has a clamp bolt. Looks like this would mount it securely enough but not sure whether runout in the assembly could be an issue.

Is all this necessary?
