I do put the ROPS up and wear the seat belt on the hills. Where I am at up down is not an option. I have a very small part at this angle, takes some getting used too, need to go slow, if you do not have an out at the bottom just plain don't want to do it. I have another spot with a wall, there you mess up you are plain screwed, its flat up to it. It just that if you move the controls a little wrong your going over and it would not take much. I won't go near that with out the ROPS and seat belt on.Should you mow up and down the hill instead of at that angle?
