I am in the market for an older (70's / 80's) used Simplicity riding mower. One of the guys I work with Heard this and mentioned that they were notoriously slower (presumably when compared to similar models of other brands), although the hydrostatic trans weren't as slow as the geared. I've looked around online and can't find anything to support or refute this. Does anyone have any experience with this one way or the other? It won't really affect my purchasing decision as speed is not a large concern for me, but now I'm really curious. What do you guys think on this subject?
