The John Deere mower conditioner is one of the better accessories for storing batteries. The reason for this is that once the plastic blades and other parts are removed from inside, you are left with a large area to hide a battery and other electronics. I was able to fit a servo which allows me to steer the mower conditioner using a wire to the tractor. The Fendt 936 has four ports at the back of the tractor, there are two for the positive and negative of the battery, one for the servo signal which is generated by the tractors microcontroller and a communication signal to tell a microcontroller in the mower conditioner to turn the lights on in sequence with the tractor.

Details of all the battery storage ideas can be found on the RC Tractor Accessories page.
