To me, that is a primative rider. The bagger is way to heavy for the machine, and can cause premature cracking of the deck where that motor hangs off. It is relatively slow, and the cut does not appear great to me. It seems to me that it is fairly underpowered as well.
I would not give more then $2500 for the whole deal myself.
Maybe it would be a great machine for you, I am just not real impressed with that machine.
Not sure if it's the same model, but a mechanic at my local dealer is selling his '97 Scag SuperZ(?) with 61" deck and 800 hours. The original 22.5 hp engine was replaced (after being run with low oil - that's how he got it from American Freight Lines) with a new 24 hp Kaw, along with the PTO clutch and all belts. He's asking $2800. Does that sound right to anyone familiar with this Scag? I hope to check it out this weekend (primarily to be used on 1-2 acres residential). Thanx...
