So, I get the batteries in the mail yesterday. I put them in, flick the on switch, the wheels start turning. I adjust the ball speed knob, they move faster. I hit the oscillation and elevation buttons..things start moving. However, the metal rod that turns the ball hopper spinner/feeder thing is not turning. I turn the ball feed rate knob, wait way longer than the 10 second delay...nothing. I'm hoping that this is just a function of a barely charged battery....otherwise, how much will it cost to put a new motor in for that mechanism? GRRRRRRRR.
