Three point 12v sprayer

[CreekRRTRN]

I have a three point boom sprayer with a 12v pump. It currently has alligator clips that run to the battery. The tractor has a 7 pin trailer plug. Is there a way to convert the alligator clips to a 7 pin trailer plug? Can I simply buy a 7 pin plug from tractor supply and attach the live wire to the live pin and the place wire to the ground pin? Any assistance is appreciated!

make and model of the 12v pump?
more so need to know max amp's it draws.

does the pump have a electronic pressure switch on it, so it turns on/off automatically pending on pressure it senses? for use of a hand wand? or due you need to manual turn the pump on/off with a switch?

gauge of wire ran to the aux connector pin on the trailer plug, and fuse it might be connected to, might be another limiting factor.

for the pull behind sprayer i have with 12v pump,



i have a marine battery used for trolling motor, or sprayer, or some other 12v stuff if i need it. and just place battery on the pull behind. and strap it down.

i can connect pull behind to truck, or tractor, and then run an a regular 110v extension cord between the 2 110v connectors. so i can feed the wire through vehicle and up to battery, or around the seat and up to battery on tractor.

i tossed optional trailer plug to 110v connector in there for ya. for an idea.

===============
a note / warning, alternators on tractors can be rather small, and just enough to run lights and the simple electronics on a tractor. if 12v pump pulls any sort of amps you could run the battery dead, and if you turn off tractor it may not start up due to dead battery, you may want to let tractor set there an run for some time after using sprayer pump. to make sure you have enough charge to restart the tractor.

some manufactures offer an "optional" larger alternator, for extra electronics, Cab tractors normally get larger alternator by default, were as open station tractors with simple roll bar will most likely get smallest alternator possible.

===============
EDIT: i forget to draw in the 10amp fuse, and a 110v regular light switch i have mounted at the pull behind sprayer.

forget to mention reason for male vs female ends, is i have caught the wires on weeds and pulled the extension cord ends apart, by placing ends this way, i won't have any female ends that stick out, and dangling that could come back and hit the tractor or rear of vehicle and cause a spark to happen.

It has a toggle switch to turn the pump on or off and it does have a wand sprayer. It's a tractor supply/county line sprayer so I'm not sure about who manufactures the pump. The tractor is a Massey ferguson 2605.

I had not thought about attaching a deep cycle battery to the sprayer. I wonder how long that would run te sprayer? I'm typically using it for a few hours at a time.

Here is a link to the sprayer Fimco Large 40 Gal. 3 Point-12V-Bolted Hitch Sprayer - Tractor Supply Co.

there should be a name plate or stamp directly on the pump housing itself. with make/model and denotating of amps, GPM info.

manual i do believe for your sprayer... (double check for yourself)
http://www.fimcoindustries.com/images/manuals/LG-40-3PT-12V-BOLTED(FM2036).PDF

in above manual denotes with picture were you can find model number of the pump.

page 3, denotes 7.5 amp fuse built directly on end of pump, and denotes 4.5 amps at 30 PSI running.
going to assume pump draws upto but not over 7.5 amps, when initially turning on. and drops to lower amps once motor has started to spin.

ya just need to find out were the "aux pin" on the 7 pin plug runs to, as far as the fuse and/or relay, and what it is rated for.

your time will vary some, from current tempatures, to how much pump is cycling on/off, how much charge the battery has taken. to how many amp hours the battery is rated for.

i get through nearly 60 gallons before the battery and pump i have runs dead. but other times only 20 gallons, but normally when its spraying season, the battery also gets used for trolling motor for a raft, and use for a 12v air pump to blow up rafts and suck air out of them, some lighting at night, with a small cheap trickle charger, it is hard saying if battery is fully charged half the time. and generally everything happens on weekends, so there is no real time for battery to re-charge.

I use a Trolling Marine Battery for a 12V 15gal sprayer in the bed of a mule. It will run the sprayer thru lots of refills without a recharge. Much easier to use than rigging up wiring. I can also put it in the truck bed or the little dump cart behind the riding mower for spot spraying as well.
I like the battery much better than a hard wired power source.

Glad to see your success with that.. I had the same idea and yesterday while in Wichita I bought a NAPA deep cycle boat battery to use with my 25gal sprayer.

I bought the same sprayer this spring.

4.5a is not a lot of power. About 54 watts. Less than the headlights, so unless you are spraying at night with the lights on, your tractor will likely handle it just fine. Almost every CUT I looked at had a 30-50 amp alternator, and all the cooling, fuel pumps, etc are mechanically driven. The tractor is not drawing a lot of power on a regular basis besides a few relays, the cruise control, and brake lights so it should be able to keep up with 5 amps just fine.

Make sure the "always on +12v" is wired on the 7 way. It's not necessarily required and on my lot of trucks, you have to manually add a fuse if you want to use it. Not sure if they automatically wire it on a tractor 7 way. Make sure the fuse and wire is rated to at least 7.5a so you don't melt the wires if you are running it for hours.

FYI, most deep cycle batteries are between 60 and a 100 amps depending on group size. The RC number is the number of minutes the battery can sustain about a 20 amp*hr load and keep the voltage above 10.5 amps. Your pump probably isn't rated to provide the right psi and flow at only 10.5 volts and there aren't any ratings for run time at 5 amps and over 12 volts. Bilge pumps I looked at to move water into tanks had noticeably different head and flow ratings for being power from a running engine vs just battery voltage.

My advise is to make sure you keep the switch inline handy because the only way to start and stop the sprayer is by cutting power or getting off and turning the valves.

I ran mine the first time off the rear work light prewire and it did fine. But because I wanted to run another pump that that needed more than the work light wiring can safely provide, I just ran a new line to the battery with a fuse right after the battery connection. I would suggest using the tractor power instead of a free standing battery unless it is your only option. The sprayer pump will be much happier using the alternators 13-14v instead of the 12.2 to 12.6v of a free standing battery. At the higher voltage, the current draw will be at a lower amp rate and will be able to maintain pressure and volume better and will run cooler.

I have mine wired to the tractor battery with switch in cab. I cut wires behind switch and have connection between tractor ( just like what's on the 15/25 gallon atv sprayers at the switch)and sprayer pump. Switch and leads stay with tractor when I disconnect. I thought about using the plug because I could spray with different tractors, but then it would open up the can I borrow your sprayer can of worms.

I wired a 110 volt covered light switch, to my battery, then ran it to my back fender and hooked to a 110 volt outlet. I put a 110 plug in on my 12v wires and just plug into the Outlet Box. I can turn sprayer on and off in my tractor seat. I built a sprayer boom to spray the whole yard. With a garden gated wye, I can turn the boom off and use the Hand Wand or use Both at same time.
