We use the disrupters instead of a chopper in wheat. Mounted all 9 of them in a staggered pattern on a keystock grate and put it in the rear position. The front two grates are slotted. We are not running any spiked bars, and it totally destroys all of the straw if it is dry. Does a better job than a 9610 chopper in all the conditions weve run across so far (the 9610 we cut with belongs to a custom cuttermaybe the knives are dullIJ) As for power consumption, I have no idea, but dont notice a problem.
