Machine possibly too large

A few days ago we noticed that our machine may not fit into the 24x12x12 box with the long extension arm out in front. We will need to fully dimension the whole machine to see if this is indeed the case. If we need to, we could possibly couple the extending front arm to the front axle so that when the machine first drives forward into the slot, the extending arm will flip down into the slot. This way, the machine will initially fit into the box but still allows the front arm to block the flipper.
