It's a 1950 Pony. Granpappy said it was two years old when he got it in '52.
On a side note, the dealer who sold me the GC2300 is letting me demo a 48" Pittsburgh rotary. Did about two acres of 3' to 4' grass and it didn't even phase the tractor. The only thing that worries me is engaging the PTO. Even at idle, it really seems to jolt the tractor when you engage. Is this the nature of the beast, or can I do anything different? Kind of miss having a clutch to "ease into it".
