To the OP... Is there a good reason you can't just trim the trees and be done with the problem?

They are prettier the way they are is all... Has anyone ever heard of a BX going over without a loader or backhoe or ROPS being attached and WITH a 60" deck? That I think is the key more so than even the angle of the ground. Those implements raise the center of gravity so much. Seriously, picture a BX with a 60" belly mower and no ROPS. That would be a ground hugger. Heck the 100 pounds of ROPS probably contributes to the problem more than aids. As described, it would take some pretty extreme slope to take it over - I think.
Ill try to get a pic of my front yard as requested. Thanks guys!
