slope percent

My grandmas woods you have to go down a hill to get to it then she has a big hill in the woods and I have a tractor I want to take back in there but don't know about going up these
hills I'm going to find what percent they are but what's the biggest percent grade you guys would take a higher row crop tractor such as a fleet line Oliver or mh 44 or farmall m up?
We take our 8n and case 530 with a loader up them and down them and they dot have any trouble.
 
I have hills on my place that go up 60' over about 600' run, so I take that at 10%, it works tractors pretty hard going up with a load.
 
That depends on a lot of things.... but generally I think once you get pushing 25% grade you're really starting to ask for trouble. I've gone down hills with some gear that was probably in excess of 80% grade... but you don't climb those grades and you wouldn't do it with the tractor you're talking about either...
So I think you best keep it under 25% and ideally a good deal less than that.

We farm ground that is up to 19% slope, It's OK going up and down but gets nerve racking going across, you don't want to go very fast in case you get into a hole or wash-out on the lower wheel.
 
What Coonie said is the way railroads rate their grades. 2ft in 100 is a 2% grade. 2% on the tracks is a very stiff climb.
 
(quoted from post at 21:11:41 07/30/15) Slope of a grade is that simple... it is rise over run. 1 foot up for 100 horizontal is a 1% grade.

That is what I've always heard. 8)
 
If you are not used to hills, you should not ask for advice on a specific grade. The problem comes when you attempt a hill that is completely out of your experience and you don't have a contingency plan to escape any problems.


I regularly attack 40% and greater slopes with 2wd tractors, up and down. I regularly transverse slopes in the mid 20's. When I square bale one section of a strip, the square bales come out and then roll a few flips down the hill, behind the baler. The nose of the tractor leads the back by as much as 30 inches, or one full row of corn.

I have a hill that rises from 1060 elevation, to 1312, within a 1/4 mile of linear travel. I farm the bottom of the slope. You just do what you have to do. I have crested slopes in excess of 50% over a small distance, and that is the key.


You need to be experienced on the hills before you just attack one. try it on a quad, or a lawn tractor, or a truck. If you wouldn't take your truck on it, leave your tractor off of it.

I wish you the best.
 
I think you're about to get in big trouble, if you ask that question on a tractor without any ROPS. All it takes is one small moment out of that entire slope, where you over-balance and go over backwards. Particularly if you get confident and get used to doing this, and start hauling a bigger and bigger load that pulls backwrds.
 
Buy a logging winch for the 3pth on your tractor. leave the tractor parked , and winch the logs to you. fooling with slope can go bad real quick. We had grades in the bush that a goat wouldn't think of climbing and we dragged logs up or down. Works best with snow on the ground.
 
Percent slope is just simply rise over run. However, to find the degrees of a slope requires trig - it is the arctangent of the rise divided by the run.
 
I was raised on hills or what is called rolling ground. I never thought about how steep was to steep. Seems you get a feeling just looking at it. We farmed everything except what dad called the ravines. Some we would drive the tractor thru but didn't farm. I had a job mowing Ohio Turn Pike roadsides when I was 18 using a farm tractor puling gang reel type mowers. At that time we mowed fence to fence. They had low mower machines to mow the areas around the bridges and the banks where one tire wanted to slip on the farm tractors. One was a Ford and the other was a Farmall H. We never rolled one while I was out there. No ROPS on farm tractors in 1956.
 
I think if you have to even ask a question like that your not experienced enough. Now im not knocking the experience you have dont get me wrong. Its, just i would hate to hear about you getting hurt listening and taking someones poor advise.Just because they might have done it once dont mean youll be able to. Just be safe
 
Try walking up the hill with a bag of fertilizer. If you are puffing hard at the top then it just might be too steep!
 

With any load on a front loader, 2% may be Deadly..

I will NOT mow on any grade steeper than 30 degrees (and that is plenty too much)...

YOU are the Operator and responsible for your own Safety... (Captain of your own ship)...BE CAREFUL.....

If it don't Feel Safe, it probably is NOT Safe...

(quoted from post at 14:26:23 08/01/15) How do degree and percent compair?

30 degrees would be 33.333 % Ninety is vertical. Nothing can climb 40% unless there is some kind of chain or gears or cogs involved, like the cog railway here in NH.
