OMG, I dont have to worry about hitting anything. With that trail mower, you better not hit a rock or a large stick.
The key ingredient to the roughcut mower is that it has a single swing away blade.... The trail mower has 2 fixed blades, which is a recipe for problems if you hit any fixed or large objects.
The roughcut is not designed to cut grass around the house. Its awful at it. It does exactly as it is named.... Rough cut.
