I have sent the link to my brother to follow up. I am not sure he will as he the reckons the smaller utility handle tank is good for his yard. Almost a full tank every time he mows. Probably is best as keeps the fuel fresher.
I wonder if that guy wrecked a Super 600 He might have other bits that we need more. Like a spindle, a genuine belt and the proper pulley for a PT. Can not see a way to contact the seller.
