My 1995 520H on the left (425 hrs) and my 1993 520H on the right (810 hrs) . Both run GREAT! The '93 has a foot-control for the Hydro and is going to get a "Resto" this winter. They go along with a push blade, a #79360 Blower with 42" wings on it, a 42" re-cycler deck and a 48" SD deck. These are the big brothers to a late-1970's C-101 I have as well.(The C-101 comes with rear discharge deck and single-stage blower for it) I'm toying with the thought of searching for a nice tiller.
