I grew up five miles from Unadilla where York rakes are made. All of the local town highway departments had a towed York for the dirt roads. I've seen them pulled with graders and pickups.

I don't have extensive experience with rakes, but as others have said York rakes are used by the local road departments on miles and miles of gravel roads. They are a local product-but they certainly are robust to handle that kind of use.
