thanks to all for the good info. It's really nice to have a forum like this for us uneducated types.
the ss16 is still soldiering away, but it really needs a general going over. I too lament the days when you could buy a "real" garden tractor.
I remember my dad buying and using a minnie mo walk-behind tractor on our garden plot. Never got enthused by that type of tractor, need a place to sit down HA
again thanks to all for the kind replies.
