Subject: RE: dpilot 83- ATV spray boom

I used to have a 15 ft boom on the Polaris 400 with 2 electric Sure Flow pumps each one running one side of the boom when I planted beans in 30" rows. It was pretty slick for spot spraying. You had to slow way down when you were spraying but could quickly zip up and down the rows only spraying spots where you needed to. I had toggle switches where I could run one side or the other or both. 1st pic below

The small ATV battery and charging system would keep up for a while but pretty soon you could hear the pumps slowing down. I also noticed the life of the ATV batteries were pretty short like only a year or so. After that I started putting a deep cycle battery on the front rack for running the dual pump setup.

I would also use the large boom for spraying the yard in the spring but it was unhandy around trees, buildings and obstacles.

I've since went with a little different setup. One pump runs a short 3 nozzle boom which is great for field perimeters, or spraying gravel drives and it's set up with non drip nozzles.

The other pump output is into a tee. One side goes to a hand wand for spraying around buildings, poles trees etc. The other side goes to a shut off valve and then onto a single wide broadcast nozzle that will cover 14 ft. I now have a 3 position switch on the handle bar that lets me alternate between center off or which pump I want running. It works out nice for yard spraying or large gravel areas. Flip the switch to one side and you get the short boom that is just about as wide as the 4 wheeler tread for going along edges, buildings or obstacles. Then you can switch to the wide broadcast nozzle for larger areas or wide open expanses without worrying about a boom flopping around.

Pics 2&3

Nozzle clamps I used are for 1/2" round pipe. I used regular 1/2 plumbing pipe to make the short boom and it simply slides on a couple pins on brackets bolted to the 4 wheeler rack.

I'm in the process of building something a little bigger and plan to mount it all on a 3 point carryall for a little 8N Ford. It's been switched to 12 volts so it should be easier to run the single pump. Plan on running 1 pump but still being able to switch between a short boom a broadcast nozzle and hand wand. Going to have a 70 gallon tank mostly for spraying yards, ditches, driveways, around buildings. The 30 gallon tank is just too much weight on the 4 wheeler and is starting to crack and break my rear rack. Seems I always fill it full but still have to make a couple trips.

Be sure to get a check valve for a boomless nozzle so it's not slobbering same for the boom nozzles get the kind with built in check valves.

If your spraying around obstacles go boomless less hassle and much easier to set up.

Still a work in progress but I made the carry all 6 ft wide with T&G 2x6 treated boards and surrounded the edges with an angle iron frame. Yes the long carriage bolts need cut off flush yet. The short boom for the rear is short pieces of angle welded to 1/2" black pipe which will bolt to the rear angle of the carryall. It has holes drilled with welded captive nuts on the back, The wood is counter bored to make room for the captive nut and bolt passing through.

Tank is not here yet so I'm waiting on it to finish plumbing and completing this.
