Thanks for the replies, but if you're not supposed to run a box blade backward then why does it have a rear blade?
Also, this video from everything attachments shows Peanut running both directions.

If it's not recommended, then why is it shown in every "how to box blade" video I've come across?
I was more afraid of flipping then just running out of power/traction.
