After looking at several options I`ve pretty much decided on getting a Kubota RTV X 900 to use here on the farm. I don`t want anything that goes too fast so the kids don`t get hurt and we won`t take it on the road so I think it will serve the purpose and be a real upgrade over the 2001 Yamaha 4 wheeler I`ve used all these years. I`m sure some of you have these so just wondering how you like them. Have any of you installed the coast valve ? Do they really help take away the sudden stop of the hydrostat transmission ?
