Slope...what is safe?? Anyone here ever roll over?

The one universal thing you will see in almost all roll over tractor accidents is the FEL raised too high. At least the pictures of almost every one I have ever seen.

So for time being let's take the FEL out of the equation.

I thought a 45 degrees as it relates to hill sides is considered a 100% slope. So that picture of Moss Road's is a tractor on a 100% slope?

Yep. 100% slope. 100% grade. 45 degree angle.

too darn steep to be messing with..

Yeah, there's a reason mother nature has ground cover! :laughing:

I could ask your question another way;
Why do we always have this confusion about % slope and degrees of slope. Why in heck can't we all just use the EXACT same nomenclature when we talk about grades. Why not just use % slope. As in this is a 66% slope. Why do we need to refer to slope in degrees? Doesn't % define the slope exactly?

Both will define a slope exactly, but I contend that it is more visually obvious to specify slope by pitch. So, a 100%, 45-degree slope is a 1:1 pitch slope. Or, more commonly, my roof is a 3:12 pitch: 3 inch rise in 12 inches of run.

That works if you are a roofer, but at least it does make sense. I think degrees is easier. Grade is not something I would recall.

A square + B square=C square. Or put another way the sum of the squares of each side of the triangle = the square of the hypotenuse. Or so Pythagoras seemed to think. Learned that one in 8th grade math. Yeah I am old enough to have went to school when they actually taught some things.

The carpenters call it the 3-4-5 rule.

In the civil engineering world slopes are almost always described as percent slope or run over rise, such as 3 to 1.

Yet the highway grade is expressed in %.

Yet the highway grade is expressed in %.

And the very first thing that pops into my mind when I see one of those signs is: "how much is that in degrees".
