How Steep is 30 Degrees? http://ventrac.com/slope
:: Most people don't realize how steep a 30 degree slope is. Field Service Advisor, Eric Hovan, demonstrates how steep a 30 degree slope is by first walking up and down and then driving the same course with a Ventrac 4500 Tractor. 30 degrees is equivalent to a 58% grade which is another way to describe the magnitude of a slope.
