I don't know that the real story is with Vishal's departure, but regarding the collar, I agree, they should have been checked before the first one was sent out. Given the timing, the first one may have been sent out after he was gone. Nevertheless, KA has resolved the mowing height problem with the collar. I had them send a collar to someone who experienced the problem and they do allow the correct mowing height now, but you do have to push up the motor from the bottom to obtain the full height. So sorry for the trouble... If you have one of the long ones and are unsure of trimming it, then request the collar from your dealer.
