Radio Controlled John Deere 9560R

Yes pity to have to take apart a new servo but yes you could take the board from one of those, it should be strong enough. You'll probably go through a bit of trial and error before you settle on your final design.

For the trailer you just need to pick a battery that is inside the voltage range of your servo. Connect it to the positive and ground on your servo connection. Then connect a ground wire and the servo signal wire back to the receiver in your tractor.

And yes the power from the rreceiver should be fine for the drive motor without need for another connection to the battery. You can always rewire it if you measure a voltage too low later on.

Ok i got the motor today and I put it together its working good but I don't know If I under stand everything about the servo esc so it says I will connect the servo to the reciever and put the new motor where the old motor was but where do I connect the battery to the whole system do you connect it to the servo somehow I don't know where you would connect it

Hopefully I have the rest of the parts next week to start building

Well on my receivers there is a wire with a battery connection on it but they are for old rc helicopters so maybe they are different from yours. What type of receiver are you using?

Are you confident you know what to do with the servo ESC? You don't have to replace the potentiometer with two resistors but it will probably get in your way if you don't. For a quick test you can wire the motor, make sure your controller is in the motor stop position and plug the ESC into the reciever which is connected to the battery. The motor will most likely be spinning so slowly adjust the potentiometer until it stops and that should be it, you should now have speed control by moving the lever on your controller.

My reciever is a 3 channel fly sky reciever and it connects to the battery by a regular esc. I'm pretty sure I can do the servo esc but the problem i have yet is where to connect the battery and what battery to use

[dan]

I got a futaba 3004 servo today so I can make the esc I think I know everything how to make it but like I said I don't know where the batter would connect because I don't think my reciever has a spot for a battery so where would I plug the battery in at or could I make it work with the reciever

[dan]

I think I found something that might work for the battery a turnigy reciever controlled on/off switch look at it online it has 2 positive wires where one goes to the battery and one goes to the motor and then the negative motor wire plugs into the battery and then it has a cable to connect to the reciever if you would look at the schematic on their website could you tell me if this would work because I already have one that I was going use for the lights but I can use it for this if it will work

[dan]

But somehow I would have to run the power through the servo esc is that possible and how or can I run the battery straight to the servo esc and then through that to the motor

[RC Tractor Guy]

Sorry for the delay. Okay this changes things a little, I'm not too experienced with receivers and the ones I have all have a battery connection so presumably some kind of voltage regulator. What kind of battery are you using?

For each channel there should be three pins these will be ground, + voltage and signal. If your battery is 5 volt or lower you should be safe to connect it to your receiver making sure you don't mix up the pins. In the image below he shows where you need to connect the wires but just to be sure check which way you normally connect a servo to it and you'll know what each pin is from that. I wouldn't connect a voltage higher than 5 volt unless you're sure the receiver can take it.

If your voltage is much higher I think you will need a regulator to keep your voltage at an acceptable level.

I'm not 100% sure but the turnigy receiver controlled on/off switch appears to take power from the battery for its load only, I think the actual internal circuitry might be taking power from the receiver as it should be controlled 5 volt whereas the voltage for the load could be as high as 30 volts.

[dan]

Ok I received my reciever and it has a battery port on it now I just have to get a 5 volt or lower battery and then plug it into the reciever right and then do the servo esc and if it into the reciever and the plug the motor into the servo esc is that all correct

[RC Tractor Guy]

I had another look there and I seen it says power from 4.5V-6V so anything in that range should be good. I seen as well that you can buy what's called a "receiver battery" which I've never heard of before but they have the right servo style connection for your receiver and come in different voltages.

You could use 3 (4.5V) or 4 (6V) AA batteries for testing if you had a way to connect them to your receiver without shorting anything. Maybe use some jumper wires for the connections.

[dan]

Ok I'm going to get a reciever battery and which would be better 4.5 volt or 6 volt does 6 volt have longer battery life

[dan]

I got the servo out today and I tested it and it was giving off 2.5 volts do you think that will be good for the motor and exactly how to I make the servo esc I connect the servo motor wires to the new motor and then with the resister and the pot I'm not quite sure what i have to do there

[dan]

What size resistors would I need or how to I figure that out

[RC Tractor Guy]

Wait how did you measure the 2.5 volts without a battery on the receiver? 2.5 volt would probably be too low to get full power from the motor. I'd go for the 6 volt battery to make sure you have plenty of power.

I used 1k Ohm resistors for mine. Search for how to make a continuous rotation servo and you should get lots of examples the only difference is you don't need the gear part just the control part. Here is an example
