Need help with roller pump installation

[kubota4me]

This is a cross-thread from Kubota specific section because I didn't know what the most appropriate section was. Apologize in advance if I did anything wrong with that regard.

I currently have a Fimco 3 point 40 gallon sprayer on my L4400 with the little 12 volt electric pump on it that it came with for weed spraying. I want to put a power takeoff driven roller pump on with a pressure release valve and coupler so I can put a garden hose on it to use to put out fires for prescribed burns. Does anybody have a link to a diagram or picture showing a setup like this? Any help is greatly appreciated!

Couple of pictures should help. First is a simple drawing of the plumbing on my homebrew boom sprayer.

This picture shows the actual sprayer manifold set up. The pressure gauge shows 44PSI against the two closed solenoid valves, the regulator dumps the pumped fluid into the line connected to the top of the tank. On my sprayer, the line extends to an inch or so above the bottom of the tank to agitate and mix the solution.

The last picture shows the roller pump hook up. The torque arm is chained to the drawbar. It's a short piece of angle. The line on the right side of the pump is the suction, the left is the discharge. The discharge line is plumbed into the bottom of the manifold, and is the line you see going into the elbow, then pressure gauge, then 2 solenoid valves, then the regulator/relief valve in the picture above. Hope this helps. Mark.

It seems I have a problem. The bracket seems too wide for my tractor because if I raise my three point with the lifting arms it could possibly damage my pto shaft and then I'm talking big bucks for repair bill. Have any of you seen this problem before? It would seem that the solution would be to short the right side of the bracket. Does that sound reasonable?
