The first time I had anything to do with this was complaints from operators of Massey Ferguson 8100 series tractors, we were dealing with two models, 160hp & 200hp. The complaint was that the steering and hyd would stop on steep slopes and due to the hyd press loaded clutch, it would also loose drive.
I rigged up a device on the inside of the cabin window to measure the angle for & aft as well as another for side to side.
I then drove the tractor until it stopped on a steep slope, I then read the angles both ways to be 26 degrees, this was very steep and had me twitching I can tell you. I did not feel safe at all at this point and when i tried to walk up the hill I had jsut parked on, it was too steep to walk comfortably and I had to climb more than walk.
Other times I have had to check parking brakes and the OECD (I think) standard for tractors is 17 degrees (maybe someone can correct me) for and aft. This is steeper than it sounds.
On other occasions when we have needed to try to fix gearbox problems that only become evident on slopes, they have been around the 20 degrees and once again, this is a lot steeper than it sounds!!! So always be comfortable and if you are not, dont go there.
To help with stability, you can always adjsut your rear wheel track out. This does help, but be careful when adjustin the front as it only gives you a false sens of security. It does not make any difference having the fornt adjusted for stability.
I hope this is of help to every one.

Some months ago I went and used a 48" level with digital readout to measure some slopes in the flatter area that I bush hog. The steepest little piece was 18*, felt like a lot more [I was going backwards/up and forwards/down the slope, not laterally-- the ground is way too lumpy to even think of lateral angles over 8-10*].

Some of the back areas are 25* or more, but I haven't gotten to them yet.... I would not like to lose hydraulics with EHSS, though I don't think 25* would be enough to do that-- and I don't think I'd try anything much over 25 anyway. That is getting pretty darned steep, and with R4s traction becomes the limiting factor at some point. I was on the edge of needing 4wd for 18* backing up with the soil type on that hill in normal conditions.
