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

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

The problem I always had with that old Indian is I could never remember if his name was "SOH CAH TOA" or "SAH COH TAO".

Yeah, and if you look carefully Jstpssng got it wrong because SOH is Sine = Opposite/Hypotenuse NOT adjacent.

While the mnemonic can be useful, it is pretty easy to mess it up.

Here is something else to consider. Are you ever without your smartphone nearby? I am not. Why remember a mnemonic when you could write out the definitions in a simple PDF and keep it with you in your smart phone? I have dozens of manuals for complex systems in my phone for browsing offline if needed.

But for that matter if you are in communication with the internet, you have the world's largest reference library in your hand. Think of that. Yeah, all the knowledge you could ever want about things like math and geometry at you fingertips. So if you cannot remember SOHCAHTOA or remember what stands for what, heck just google it. It only takes a few seconds, and you can find trig converters on line there also, or conversions and lookup tables for anything on earth. So you don't have to remember old Indians if you don't want to.

And I can't even remember what the definitions mean, sine, cosine tangent? I think I have it in book somewhere...

Or simply Google it.

Just remember one sine = opp/hyp

The rest are trivial.

I think at this point in life I'm math challenged, don't even know what this is supposed to represent. But it doesn't matter, cause I'm not calculating anything like that. If it looks steep I ain't going there.

Keeping in touch with my family is the #1 reason I carry a cell phone.
#2 is work.
#3 is looking stuff up.
I look stuff up all the time, be it for work, play, general interest, maps, satellite views.... it sure is a nice thing to have many libraries at your fingertips. :thumbsup:

On car trips, my wife takes a printed atlas, looks stuff up on the cell phone, and looks at it on the big paper map. That's my only gripe on cell phones, the screen is too small.

I keep a list of my bottle opener collection on my phone so I can see if I already have something when we're out and about and find something. Stuff like that makes it worth the money.

Opposite over hypotenuse.

This is Canton Ave. in Pittsburgh. It's one of the steepest roads in the world. I've driven it a couple times in our car. It gives me the creeps. It's listed as a 37% grade which is about 20 degrees. Now considering a Power Trac slope mower is rated at 45 degrees.... YIKES!!! :laughing:

Just remember one sine = opp/hyp

I have a sign on a high post in use at my driveway,

Just a 90 degree phase.

There is a street in Harrison Ar. that looks kind of like that middle picture, but I believe yours has it beat.

The last slope in my driveway is uncomfortable to walk down. One reason is that it is gravel, and the fear of slipping in pretty great. I have never seen a two wheel drive truck that can start on it. A two wheel drive front wheel drive car with traction lock might be able to, but will sure dig a lot of holes. I know, I fill the holes all the time from people coming up the drive too slow.

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?

Had an uncle that worked for several years mowing right of way for the power company. Every rollover he had was due to flats. They learned quickly not to put fluid in the tires because that caused them to be less pliable and let the sharp stumps and limbs they were creating puncture the tires more easily. They found that big fat tires, low pressure and no fluid was the best way to go, especially mowing the really crazy stuff they had to mow.

I have a stretch in my driveway that is the same. If you don't hit it with a head of steam you won't get up it with 2wd. When I put new tires on the 3000 I went down it one time before the tires were loaded. That was more than enough for me! Wheeeeeeee!!!!

Did you have a good time, trying to keep it between the ditches? Lots of fun. I did it a couple of times when I had the little Kubota B7500. I had been using 4WD but switched to 2WD up on the driveway (asphalt) and forgot to put in back in 4 wheel going down with a load in the bucket.. Oh boy.. was that ever fun... whoooo hooo..

Why are people cutting grass on a steep slope do you all hate tall grass that much?

 

[Evets Tsorf]

Never really got an answer regarding tractor stability with a brush hog attached. Again on my tractor the brush hog is a bit oversized for the tractor. With the weight of that on the three point very low to ground I would think it would increase stability ( more weight lower than most ballast boxes ). What am I missing in this equation?

I thought the world steepest hill would have resulted in some kind of really cool bike pile up.
