Right, and that requires an 'H' bridge circuit. See my explanation of 'H' bridges above and the complexity they add to the circuit.
The main thing we want to do is control the speed of the motor. The direction it turns is controlled by the transmission or the reversing relay, so why go through the complexity of the 'H' bridge, at several hundred dollars, to do what can easily be done with the original machine?
What we're doing is specializing and contouring the electronics to fit our application. Alltrax is making a unit to fit many applications, the problem is this multiplies the cost considerably.
