Just a little project of mine. Had some scrap lying around and decided to be constructive for a day instead of the opposite. All it needs now is to finish the plumbing and a good coat of paint. Hopefully the pictures worked.
I have a FIMCO pull behind sprayer that I converted to three point. In order to operate the pump I added a trailer outlet to the back of the tractor with 12V switched by a switch located just below the seat in easy reach by my right hand. My next project will be addition of a switch on the sprayer that would detect if it is lifted or in working position and turn the pump off when I lift it. Another possibility is a motion switch that would turn the pump off when the tractor stops.
I will post pictures but you will have to wait some time. I am currently working in India and have not an idea if I make it home home anytime soon.
I put that together on a spur of the moment when the need presented itself. I used galvanized perforated angle I had laying around and bolted it all together, I also reused the wheels so I can pull it to storage even full of stuff.
