Doesn't look like it.
Of course they are more prone to rollover. Didn't you ever have a tricycle as a kid. Make a sharp turn right turn and you go over the left side. Same thing happens on a tricycle tractor. Make a sharp turn to the uphill side and over you go.
Another example...
Draw straight lines between the four wheels on a modern tractor. You pretty much get a rectangle. Do that on a tricycle tractor. You get a triangle, like this... note the center of gravity. The COG moves, depending on slopes (both forward and backward and side-to-side), attachements hangin off the rear, FELs hanging over the front, etc... Get the COG outside of those lines and over you go. Its easier to move the COG outside those lines on a tricycle tractor.

Never drive across a slope with the nose pointed down hill , NEVER . As the front axle pivots in the centre it is like having a tractor with one front wheel in the middle . The weight is transfered to the low front corner and is taken away from the high side rear wheel . The front axle offers no resistance at all until the axle hits the stops by which time its all over . Thats why i mow steep embankments with the nose steering up hill , the rear axle being rigid stabilizes the tractor .
This link is no longer working. I poked around a bit, and this might be some of the same info.Here is a link to the tractor rollover demo pictures and videos that we keep talking about in many forums here on TBN. There are five pages of information there, many pictures and videos. Please read them all, look at the pictures and watch the videos. I'll make this a sticky post for now so that it stays at the top of the Safety Forum for a while.
