We have commercial Hustlers at work and they're the only mower I'll use on some of our banks. Operator error is a lot of the problems when mowing a steep bank. I watch the neighbor mow a piece of property with a couple banks that aren't that steep, but he's going full out and all he does is spin out and slides down the bank. Hustlers seem to have a little more weight, lower center of gravity. We had Exmarks and even demoed a couple others before going with Hustler. We have several guys who mow for us, but only a couple of them will mow the steepest banks we have, and yes I classify those banks as giving you the pucker factor when mowing them.
