Diy Push Sprayer

I already have a tank sprayer I can use that is set up to mount on the back of a golf cart. It has a wand or boom attachment. I believe it works well but I have yet to personally use it. I sort of inherited it from my wife's grandparents next door. I don't suspect that they use the best nozzles but I can't say for sure. Still, not a bad start!









However, I think I'd rather have a push sprayer. I can imagine me beebopping along on the golf cart with a cold one and some jams and the sprayer cut out, nozzle clog, hose burst, or something along those lines and me not notice for a moment or two too long.

If I was push spraying, not only am I automatically going to be paying better attention to my spray, I'm also more in tune with the grass and can look closely at it while I'm walking. I think this would make it easier to closely observe the grass and maybe catch a problem I wouldn't on the golf cart.

I have this pump from a methanol injection system I used to run on my truck. It seems pretty similar to the one on the existing tank sprayer. It's rated at 1 gpm, 200 psi 12vdc.





I also have two sturdy hand trucks, and I could sacrifice one for the cause.

I don't see why I can't use this pump, a hand truck (the one I would use has large pneumatic tires), a tank, a small 12v battery, mount a boom and some simple plumbing and viola! Obviously that's a gross oversimplification, but at its very basics isn't that the case?

I was thinking I could use a boom attachment made for a backpack sprayer, such as this↓



Before I dive in, do you all have any pitfalls you need to tell me to watch out for? I think this pump is already set up for 1/4" tubing. Will that be sufficient? Anything I'm not considering?

I'm wondering if I should just use a 5gallon bucket to keep the costs down, and use a sandwich bung in the lid to connect my tubing and my pickup tube to. I could keep 2 or 3 clean buckets to swap quickly from one to the next with the same lid if I was doing a big spray. I could upgrade to a single larger tank at any time, but good tanks can get expensive.

I'll look harder at the tank sprayer I already have here. I thought the specs on it were about the same, but it was a long while back when I looked at that. If it's rated for a lot more flow than I thought then this one probably won't make me happy. If I can just get performance to match that sprayer but in a pusher, I'll be happy. The Chapin that gave me the idea (I've never seen such a thing before) has a 1 gpm pump)

It looks like I'll be able to run at least two of the tee jet nozzles if I select the right ones? (I was thinking maybe the .3 gpm nozzles) How wide of a fan could I possibly achieve per nozzle? I don't know why I'd need to run 5 nozzles. I'd like to be able to cover 36-48" per pass. Obviously more might be nice, but I don't think this tank, pump, and boom I already have will spray a path of much more than that.

All that said, I'm not sure how agitation applies here. I need a little education on that.
