Boom sprayer parts

[Joe1]

I bought my parts at a local NH dealer and a farm supply store. I shopped around and found a $75.00 difference in the tank and pump assembly. I went with a 25 gallon tank and purchased a 140" folding boom kit (nice if I'm too close to a tree or fence) that had 7 heads at .2 gallons each or 1.4 gallons per minute total. It also came with a hand held spray wand. The pump looks like a standard RV pump (except that it has an on/off switch on the pump) that puts out about 2.5 - 2.7 gpm. I used a series of tees and shut off valves so that I could use either the boom or a hand held spray nozzle.

So the pump would not cycle on and off, I also ran a return line to the tank with a shut off valve. It seems to work well with the pump putting out about 40 - 45 psi. I control the pressure thru the return hose valve. This also keeps the solution mixed, although I don't think it's a problem. I wanted to make mine portable so I had a mounting rack welded together and I just bungee the rack and mounted tank to a 3-pt fork.

I wired the tractor with a waterproof marine switch on the dash and a pigtail at the rear fender. I took the power directly off the battery with an inline fuse to protect the system. I believe the pump draws about 10 amps, and the alternator makes 20 so I'm still in the black on current usage.

I leave the pump switch on when operating it and control it with the dash switch on the tractor. When filling and flushing, I leave the dash switch on and control it at the pump.

Good luck.

Joe, it looks like you did what I'm looking to do. In addition, I placed a liquid filled pressure gauge between the pump and the valve (to swith between the sprayer and the nozzles) to the sprayers and nozzles. Also, a placed a pressure relief valve between the gauge and the valve so the over pressure fluid will go back into the tank.
