Bring on the weeds \"Homemade Sprayer\"

Always needed a sprayer to do the fence row and spot spraying.Got tired of walking with the backpack sprayer, so here is what I came up with. Found a RV water pump at a yard sale for ten bucks and the rest of the stuff I had. Then so I could spray from the seat I made a scabard for the wand from a peice of electrical plastic conduit. Whole unit hangs on the quick hitch and to keep the bottom from digging into the ground as the mower deck lowers,I removed the lift arms and made shorter ones to pin the three point to the frame so it doesn't move with the deck. Works great

Second picture of wand and check out the chain box!!

Nice looking arrangement.

Nice arrangement. I am in the process of designing and building a dual tank spray rig and I never thought of building a holster for the spray gun/spray wand. For my sprayer rig I am using a gun sprayer instead of the wand sprayer you used, but the arrangment you came up with is great, it puts the spray control right where you can reach it using while driving the tractor looks like it would be a piece of cake.

Nice job . . . and thanks for the idea!

ah! I see you used the "hi-tech calibration method" like I did...you'd think they'd mold that stuff into the plastic...go figure...

Re: Bring on the weeds \"Homemade Sprayer\"

well that looks awfull! awfull good that is!! /forums/images/graemlins/wink.gif lol. I've already got my PUMP and the water tank (both out of the same RV)
I have a couple few questions.

what are you using for the pump switch? toggel or foot mounted

do you turn it on and let it run or only when you need to spray?

does it have built in pressure regulation of some type or do you let it dead head aginst the spray wand? and just squeeze the trigger after the pump is switched on? (I didn't see any wires attached to the wand which I was going to do.)

ok I think that is pretty good for now. probably revive the post and ask more questions later just to be safe when I'm buiilding.

Power is from a toggle switch in the dash. On the pickup side of the tank is a diptube that goes to the bottom of the tank.And if you look on the out side of the pump there is a tee and a small ball valve on a return line. I just set the valve for the best pressure and let it recycle the water (roundup)and spray as needed, but do not let it run for long periods.
The pump has a built in on demand switch but it surges and the spray is not consistent.

Was there a reasion you did not use a pto pump? I am thinking of building (or buying) a boom type one and can't decide what type pump I want

Re: Bring on the weeds \"Homemade Sprayer\"

Chucko, I can give you a reason not to use a PTO pump. Cost. For a small spray rig, like this unit, and like the one LAGEORGE built, as well as the unit I am building, the 12 volt pumps simply cost less yet seem to provide the necessary amounts of pressure to do the jobs.

Also, once your tank is pressurized you want the pump to shut down, I simply don't know how to do that automatically with a PTO pump. As you spray, you want the pump to cycle on, and off, to keep the pressure up so you don't have erratic pressures and so you have consistent flow volumes.

For a larger application, I would suggest tanks over 35(?) gallons, then it might be much more reasonable to consider PTO pumps. But for tanks that typically run 15 to 25 gallons, I just don't know that a PTO pump is reasonable?

Re: Bring on the weeds \"Homemade Sprayer\"

so in my case I am going for a 40 - 50 gl tank so I should use a pto pump?
