I'm looking at a 2015 54" Raptor SD with a 23 HP Kawasaki motor. It's got 161 hrs on it and the guy says i't in excellent condition and that it has just been serviced. He wants $2800.00 for it. I'm a pretty good haggler for thing I know about but I really don't know what I'm haggling for when it comes to mowers like this. I've read good things about the mower here so I guess it's a good machine. This is what it looks like... What are your thoughts? THANKS!!!!
