Rear 7 pole connector

[rjfoster]

I have a LS G3033H and see that I can mount a 7-ploe connector on the rear aspect of the tractor. I have a small 15-gallon sprayer that I want to connect to a 3 point carry all and wanted to see what specific type of connectors anyone is using on the rear end of their G3033. The connector that is one the sprayer is a 2 wire male - female plug, so I do not mind changing it over to something more useful. I could see connecting a small winch to the rear aspect, so a larger style plug would be feasible.

Thanks for any suggestions.

Take a look at these.

This would go onto the tractor (Pollak Heavy-Duty, 7-Pole, Round Pin Trailer Wiring Socket - Vehicle End Pollak Wiring PK11720), do not know what the back of you tractor looks like, you could make a bracket and mount it on the back of your tractor. The wiring on the back of my tractor for this is.

Terminal Function Wire Color
1 Ground Black
2 Flood Lamp Purple
3 Left Turn Dark Green
4 Accessory Red
5 Right Turn Dark Green
6 Tail Lamp Gray
7 Accessory Red

You could this (Pollak Heavy-Duty, 7-Pole, Round Pin, Trailer Wiring Connector - Trailer End Pollak Wiring PK11700) to connect to your sprayer using terminal 1 and 4.
I just completed what you are thinking about doing.

Nothing fancy, but it did the job. I have attached a picture of the sprayer mounted on my carryall and wired into the tractor. I also attached a picture of the wiring for it, basically I plug it into the sprayer, into the tractor and I have a switch that I can operate from the seat.

I used the Ulysse Speedometer app on my phone to determine what my speed is.

The Pollak connector came on my tractor. I would go with the round connector and not the RV type as most tractor attachments I have seen use the round connector.

Perfect! Thanks for the response, suggestion and images.

Let us know how your project comes out and if there is any other info you think I can provide you with.

My neighbors dad had me install the connector on the back of his 4230, just turn signals and lights. It was a kit from John Deere picture attached. The kit used 16 gauge wire and the ground was just to the strap that the connector was mounted too. I had some of that plastic tubing that I got from Lowes and put the wires in that for protection.

I'd like to do that so my electric trailer brakes would work, like with heavy loads downhill.

Seems like even a small winch would draw more amps than a connector is designed for.

If you look at the specs on the connector, they suggest using 10 gauge for the ground and for Auxiliary Circuit. I would be more concerned if the wiring for the tractor could support the amps. 16 gauge I believe is rated to handle 22amps. I tested the sprayer and it used 5 amps. One does need to add the amps of all the things on the circuit. The circuit I used was on a 20 amp fuse. There is a relay in the circuit, so one could use larger wire from the relay to connector and lower gauge wire from the tractor to turn on the circuit. The specs on the relay are 40A NO, 30A NC. I had to look up what NO and NC meant and included what I found.

A LOT of hills in my part of VA. My tractor does not have electric brakes. I have considered mounting a brake controller on the tractor that has an inertia sensor and electronic brakes on the wagon and see how that works for going downhill. Still need to more research on this, the controller may not work at all if there is no electric brakes on the tractor.

Lastly, the contacts in the switch or relay are described as "normally open" (NO) or "normally closed" (NC). This simply describes what the "at rest" state is. For a relay, that means if no power is applied to the coil/trigger wire. In the typical case where you want to turn something on, you use the "normally open" set of contacts so that when you apply power to the relay, the contacts close, and power is sent to the desired device. This is used for things like turning on your fog lights or things like that. In the case of wanting to turn something off, you use the "normally closed" set of contacts so that when you apply power to the relay, the contacts open and the power is no longer sent to the desired device. This is used for things like an emergency stop switch or other more unusual "control" cases. One example is in certain multiple relay electric fuel pump setups on fuel injected vehicles to control when the pump is on and to ensure it turns off in case of the engine stalling - this is used to reduce the risk of fire (due to the pump still pumping fuel) in case of an accident and a ruptured fuel line.

My DX55 came with the 7 pole connector, and I too wanted to come up with an adaptor for my sprayer. I made an adaptor plug using a 7 pole plug, and a short 2 pole pigtail plug. Now I can plug that converter into my 7 pole tractor outlet, and have a dangling 2 pole plug to use when needed.
Then I made a new extension cord with a switch, with 2 pole connectors. It is actually very similar to JD5210's homemade version, but I used a 2 pole plug where he used the 7 pole (since I already made my converter plug for the tractor). Also, I made mine longer so I could put my sprayer on the carryall, pull it on a small trailer behind my tractor, OR my lawn mower. That's where the 2 pole plug comes in handy on the extension cord. I used this wire for my extension cord, since it is good flexible wire with high quality insulation and 12 ga wire so I won't have to worry about voltage drop over the longer distance. http://www.menards.com/main/p-2752371-c-6410.htm
It works great! The soft flexible cord is so much easier to manage than the stiff OEM wire on the sprayers and cords.

I ordered the plugs and once they come in, I will look at making a mount for the female plug.

If maybe you do not already know the following, but cannot hurt to share.

Without knowing the wiring of your tractor and what circuit you are going to put it on. Keep an eye on the amps. If you have a voltmeter it should be able to test for amps, many low cost meters will only test up to 10 amps. Most likely your spray will not go over 8 and be closer to 5. After a short period of time using the spray, take out the fuse for the circuit you have it on and see if the fuse is warm/hot to the touch, if yes you are drawing to much amperage on that circuit and will need to put it on a different circuit.

Do not know what your long term plans are for the connection, but if you plan to put bigger things on it ie draw more amperage. You may need to install a relay and dedicated circuit.
