ok i decided to rent a bed edger. they only have a ez trench and they have different models to choose. the cheapest is a 8 hp with a 1 inch wide single blade. the next model has a 6 inch wide blade that looks it would be used for doing a new curbing job. all i need to do is re do some beds and was wondering which one i need to rent. they dont have a brown model only ez trench.
