Yeah this one needs hydros serviced, and I'm weary about replacing the oil because my other snapper 36" takes 10w30, but ive never heard of the oil they recommend for these unless the oil for the part number has changed over the years.
Spindles aren't seized, new rear tires, needs belts, bushings, and a possibly a clutch (which im going to see if it's a switch first).
The deck is in fairly good shape too, just done surface rust mostly.
I did buy out from a guy who said he bought them four his son to start cutting lawns but he never did. He paid $600
