Hi, I was wondering if anyone has had problems with the newer style Grasshopper frontmounts losing traction on a slight hill and leaving a rut, so to speak. This normally happens when I have to stop in front of a tree, back up and then move around the tree. The wheel facing the slope will sometimes spin and dig into the dirt. I am not going full throttle on that tire, most of the time I will not even give 1/4 throttle on that tire. Thanks in advance!
