[Parks]

I spent my time building the drive system and the screwjack for stacking.
As far as I am concerned the cow-catcher is merely a decoration.
but seriously,
it could be used for an advantage in a shoving match - to reduce other's traction, as has been mentioned.
It can be raised but we can still go over the ramp with it down (teflon on the bottom)

Oh yeah, it goes nicely under the bar too. I find it hard to believe we managed to cram it all in there.
Thank you for your comments.
