Everyone else has had a go, so why not. I teach tractor operations at an ag college and this subject always comes up. The class disscussion usually follows a similar pattern to the one here. A first glance, narrows seem more tippey, but when you think about it and draw on your experience, people usually realise that there isn't much difference. A few days ago I posted a followup in reply to Chris Sweetland who wanted to know about brushhogging with a narrow front. I outlined a bit of theroy that may interest some and backs up what people are saying here about front pivot points etc. The only practicle way to improve a tractor's stablility is to increase the rear wheel spacing. Wide fronts have a slight edge in stability when the front axle hits the the stops but in most cases it doesn't help much. Since a lot of narrow fronts are rigged for row cropping, they can have a higher centre of gravity (this also applies to some wide fronts). Narrow fronts can turn sharper which could be a problem, but it's nothing a bit of common sense won't fix. Most rollovers I've seen involve some combination of slope, speed, sharp turns, potholes or high loads, regardless of the type of front.
