Hey guys, I am currently looking at some new to me used x7 series tractors. I am looking at getting a four wheel drive one for snow removal of me and my neighbors driveways. Also any other misc. projects I can get my hands on. I am curious how you guys like the full time four wheel drive units? Do you find they tear up lawns when making tight/sharp turns? Do they all work like the newest style with the valving built into the hydros for slowing one wheel or the other when turning? Thanks for the info.
