Best Way to Provide DC to Sprayer?

[Suburban Plowboy]

I have a little Fimco sprayer. I also have a cargo carrier on the back of my tractor for chainsaws and such. I would like to put the sprayer on the platform and use it to kill weeds.

Ordinarily, I use an EZGO, but using a sprayer is not good for the paint. The sprayer can connect easily to the EZGO's battery because it's under the bed where the sprayer sits.

What's the best way to get DC to the sprayer, maybe 15 feet from the tractor's battery?

Provide the sprayer with a dedicated battery, in a box, attached to the rear of the machine. Perhaps the fender or ROPS. Charge the battery before use.


Or, install a cigarette lighter port, change the wiring on the sprayer to a plug, and just make it super easy.

Thanks. I want something connected to the tractor's electrical system.

The sprayer takes a 15-amp fuse, so whatever I use has to be able to supply a fair amount of current.

I ran a 65 gallon Fimco boom sprayer with an eyelet on the positive battery clamp and an inline fuse. I run the wire along the frame to toggle switch in the wire and temporarily zip tie it to the grab bar on the fender. Then it goes along the frame to the sprayer. Ground anywhere.

It takes just a few minutes to install and less to take it off. If any risk of battery drain I pull the fuse. Works slick and no hours of running a permanent installation with drilling holes and related drama.

Maybe I'll do that. Thanks.

Most tractors have at least one wire in the back end of the sheet metal which stays hot anytime the engine is running. My various older Kubotas do. You might find the hot wire at a rear fender with a meter and crimp into it with a new wire leading to a plug. Buy a plug to mate with the existing wiring on your sprayer. Most of the sprayers have some kind of wiring harness you should be able to crimp-splice into (if not cut off and put on the new mating plug.)

I use a tank sprayer that sprays a path about 10ft wide very nicely for grass killer in gravel driveways. On a Kubota B2150 with front end loader I put the tank and spray arm in the FEL bucket, set it the way I want, and run the sprayer wires (which include an on/off switch and the wire clamps that look like ones on a battery charger) to the battery which is under the seat. I am lucky enough to have the stock wiring from the sprayer long enough and nicely made to reach from my FEL to the battery. Depends a lot on how permanent you want to make the rig and how much you use it.

I would wire some Anderson Power Pole connectors on a relay to the back of the tractor. That way it's switched and not hot all the time. Change sprayer ends or make adapter

I have a sprayer that I mounted to a pallet, then also mounted a battery box and a deep cycle battery it makes a self contained spray unit that can be mounted to a carry all in the rear or on forks in the front. For boom spraying I use the rear carryall mount.

I did a combination of ideas listed above. I attached the wires permanently to the battery in front of the tractor, using crimp on eyelets and heat shrink tubes.
That goes to a rocker switch in the dash (easier than it sounds)
From there to the back of the tractor, zip tying it tucked up underneath, where it won’t get snagged by brush or field debris
The rear connection is a 2 hole plug in, like you see in trailer wiring, same on the sprayer wiring.
The nice part of this is you can turn the sprayer off and on from your seat.

This is what I have on my ezgo.
