Trailer hitch carried sprayer?

[Stelzer]

Not sure of your exact plumbing mods, but installing a ball valve at the T would prevent sucking air. I like the Banjo 3 ways, comes in a variety of configurations as well.

I was talking about this T in the bottom of the tank. I wanted to see if it would empty the tank better pulling from either side if the tank is on a slope away from the inlet. Not surprising it didn't work, but I wanted to try

Did a couple minor tweeks over the winter (rear handle on bottom frame for easier loading into hitch). Used it today for the first time so took a couple of pics.

I didn't take a pic inside...but I will say the "T" for the intake did not work well. If one side was out of the water, the pump just sucked air instead of water from the other (makes sense, path of least resistance and all). I just made it an "L" going to one corner of the tank so its easy to tip and get the last of the liquid out.

I'm not going to say it is "easy" to lift into the hitch when full, but it does work. I think this is going to work out great when its just a little spot spray here and there - especially if it is some distance from the shop not needing to take the truck. Also the convenience of not needing to unload the back of the truck to slid a skid sprayer in.

You may notice I flipped the hitch bar from previous picture...it loads better with the slopped part up instead of down. Paint marks to signal when it is lined up correctly.

Pretty cool! I like these types of small scale effective solutions. What sprays/diseases do you see using it for mostly?

The usual suspects? spruce, crabapples, the random bagworms and whatever else pops up?

Yeah... don't have one specific treatment in mind.

But smaller jobs, or jobs that are further from home so i can take SUV (20-25MPG) vs pickup (10MPG, on a good day). A second (or third) person spraying some days as well, maybe. (Of course, my full time helper just moved out a town so, for now, it's just me most days...unless you wanna come help!)

Also, maybe a larger commercial site. Just looked at some boxwood mites problems there, for example. I think this will be more convenient and less disruptive to them compared to dragging a long hose from the truck or refilling a backpack sprayer multiple times. I think it will also help get more thorough coverage than backpack in less time since it has higher GPM and bigger droplets.
