Currently I run a JD HD75 48" walk behind and a JD F735 60" front mount. I'm looking to get rid of the walk behind for trade on a ztr or AWS tractor. Does anyone have good things to say about the JD X485? I've run around on a large tractor before but the AWS would have been the cats hinder. My customers don't care too much for ztr's and I have some nasty hills to deal with almost daily. I don't use the walk behind every day so the cheaper LX277 AWS also caught my eye. Not sure what to approach, going to the deal this week. Also, some estimated prices others have paid would be great! Any suggestions greatly appreciated.
