<font color=blue>Now i just have to wait for the clay/mud to dry up enough to tromp the hills. I have a couple compasses, but don't know what the heck i clinometer is, I'd guess it's that piece that folds over the compass face, and stand verticle when your using it .....but i never knew its name, let alone how to use it. But thats okay, i can handle doing it with a tape and level. </font color=blue>
Just remember, doing this will give you an average slope %. It won't take in account any sudden dips, holes,etc...the things that can cause your tractor to roll or lose control.
So, while you're making your measurements, keep an eye open for other potential hazards!
Good Luck!
