Zero turn mower style steering trial

[Brewer4377]

Between the holidays we are going to build a prototype chassis similar to a zero turn mower and control it with a left joystick and a right joystick. When we put the unit through its paces in some trials, I want to make sure that we give it a thorough challenge. Any recommendations of particular maneuvers that will demonstrate either a strength or a weakness would be greatly appreciated.

Thanks,
Paul
