It's been called a calf roping machine, a roll-a-roper, calf roper, and roller roper—no matter what you call it it's a good time. The roller roper is an excellent tool for teaching basic roping skills as well as an exiting piece of entertainment for your next event. The roller roper only requires a basic electrical connection and a 10ft by 20ft space. Pair it with the mechanical bull and you've got an indoor rodeo!
