I have a brand new roll over protection system from my brand new IS2000Z. It is in perfect condition. It has a folding top to lower the highest point if you desire, and while folded, it remains within the length of the mower, so it won't hit anything. My local dealer said that it was a $575 replacement part before shipping, so I think $400 is a fair price, but I will consider any offers if anyone is interested. Shipping will be arranged before the sale, keep in mind that it weighs about 80-100 pounds i think (its heavy). Please PM me with any questions or if you want pictures.
