Getting ready for spring

I am getting ready to start working out and around the yard with my ATV this spring, get brush cleared and start building garden beds and trails. I need to get a few things for the ATV still, but I have the winch and a small trailer. I do need to get a better trailer though, since this one actually belongs to my brother and he switched the wheels for a smaller size in redesigning the utility trailer. It is intended for hauling lightweight things around the yard, and I want one that can be used for hauling rocks for building retaining walls and the foundation for additions to the house.
