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

[buckeyefarmer]

I use clinch factor to measure slope, but that's not a standard...

There is more to it besides slope and CG. Transient CG, like when an uphill rear tire hits a rock, or falls in a crevice and rebounds are your items to consider with speed a direct contributing factor.

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.

Oh, is that what it is? Heck I used it this afternoon, to calculate where the corners of my garage are going to land.

Then I managed to the rear wheel off the ground again... and I wasn't even on the tractor. I was screening loam into the sterilizer in the back of my pickup, and had the bucket raised to a little above tailgate level. The soil was a little wet, and I suddenly realized that as I drove the shovel into it, the LR was coming off the ground. I've never worried about it until I bought this tractor, now I'm saving up for a set of rear weights.

Well that can help you find sides you can't directly measure, but the Sine and Cosine functions can help you calculate angles. or if you know the angles, it can help you calculate sides.

You can so some of this without a calculator if you can remember the special case of the right triangle with 45 degree corners, You can set up the sides in a 1 , 1 ratio and the hypotenuse will be the square root of 2 or approx 1.414. This can be handy to remember.

Sides of a triangle equal to 3, 4, and 5 (or multiples of) make a 90 degree corner.

You just need to remember that old Indian... SOH CAH TOA. (Sine = opposite/adjacent, Cosine = adjacent/hypotenuse) Tangent=opposite/adjacent.)

Decades ago I was laying out and surveying thinning blocks for precommercial thinning. I had a hand held programmable calculator (Hewlett-Packard 11C) and wrote a program for it so that I knew the error of closure and acreage before I left the woods.
It saved me a lot of time, which translated into money.

Has anyone ever investigated a roll over accident and discovered a rear tire flat?

Another thought. Does the torque of the pto shaft play a role in turning a tractor over when mowing in a particular direction?

Thanks, i remember that now that you told me!.. I had forgotten that old memory device.

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.
