Yep! Tippy as hell. Put a 250 lb dude in the cab and have them run over an 18 inch pile of dirt or into a rut at an angle. You also have to be mindful of how much you have in the bucket. Notice there aren't any stabilizer arms wider than the machine on them. A full bucket of clay or wet dirt will put the azz end of that in the air real quick if it's not close to the tracks. The deeper the trench or the farther you have to reach the more tippy you get. Also, you can slingshot your way into trouble if you spin a loaded bucket to fast. Think hammer throw without letting go of the weight. That said, they are a useful little machine when you use some patience and keep it's use to within reasonable expectations.
