There are other brands also but the Micro Trak unit should be fine.
The boost box contains a heavy pair of wires that connect directly to the vehicles battery. It also has an input and output pair of wires. The output from the Deere controller (or other brands) is connected to the input pair. The load (motor) is connected to the output pair. The boost box creates a high current PWM supply that mimics the incoming PWM signal from the controller and passes it to the motor. This means that the controller does not need to handle the high current demands of the motor directly.
