I was on my way home yesterday and spotted a a case on the side of the road, I pulled over and checked it out and it was a 448. It had ags on the back, rear tiller, three point lift, the hydraulic ports to run the tiller and a front weight bracket that looks to be factory with two weights on it, and it has the onan b48m engine. The unit looked to be in good condition with only a few rust spots on the hood, and the tiller looked brand new. How much should a setup like this cost given that the onan runs good? Is the onan b48m rebuildable, so they have any common problems? This is a nice unit and I really like the hood scoop, if it is the right price I will proably go for it.
