If you buy a tractor with a FEL and you have never used one, the manual helps a little but it doesn't really tell you all you need to know, or maybe it does but you really don't learn much until you use the loader. I learned by using it that you can turn a tractor over very easily with it, much easier than I ever thought. I never turned it over but I came extremely close twice. Rule number one should be "never try to use a FEL sideways on an incline" Even a slight incline with the bucket loaded and up three or four feet will cause it to tip. If you start to tip, lower the bucket immediately, keep it low and try to back out of it. Rule number two should be " always travel with your bucket low to the ground whether it is loaded or empty". There are some other rules in the owners manual which are also important but these were the ones that I failed to pay attention to until I almost turned it over. Oh yes, one time I did it without the ROPS up and without a seat belt because I thought that I was going to be doing work which would make them unnecessary. Never try to use a FEL, even on level ground, without ROPS and lap belt. You can turn one over even on level ground if you drive over a hole or some soft ground with a loaded and lifted bucket. The best thing to do is always use ROPS and belt while on the tractor regardless of what you are doing. I don't think jumping off a rollover is possible in any circumstance, or at least, it would not be possible for me.
