I have 2 scag foldable roll bars for sale. One came off a 36" Z-cat rider with about 35 hrs on it. It has some damage to the seatbelt (looks like it was burned by the exhaust) but the bar is fully functional and comes with hardware. $150 The other is off a 61" wildcat and was taken off with less than 5 hrs on the mower. It is foldable and in as new condition with hardware. $175 These may work on other mowers, I'm guessing the one of the 61" mower will fit many other models. The Z-cat bar is significantly narrower, but may fit other small riders.
