I built a herbicide spray boom for the new tin boat. First test run was to look for leaks, and that part went well. 2 outside nozzles do the work, and the shorter center nozzle just fills out the middle. Removable drop hoses so that precut hoses can be quickly changed to allow for whatever the target depth of the day is. I think the center drop is 4', and the 2 outside ones are 6' in this video. I'm testing with a cheap 2 cycle 1" water pump that's been sitting around here for years. When it dies, I'll replace it with a 1" Honda 4 cycle pump.
First video is with the siphon off, second video is with the adjustable siphon on, and pulling diluted pasture dye from a 2 1/2 gallon jug. I waited until my wife went back to town to paint the driveway blue.
I needed to put a coupling in the pvc pipe because of the size of the system. Being able to separate the pump from the hose will make it much easier to transport.
