I haven't brought them home as yet, but I bought 2 more Sears GT's this weekend. One is a GTV/16 with the B&S 16 HP engine (just like Big Bertha). But I noticed something different about it. It has a cast iron front axle, mine has the stamped steel axle. Thought that was odd.
The second one is a Craftsman III with 20 HP and electric lift. Been trying to figure out what brand that engine is. Too many tins on the engine to see anything. There is a sticker on the flywheel housing, but unable to make out anything on it. Just has Craftsman 20HP decals on the head tins. Don't have pics as yet.
I hope to bring them home next weekend. For now this is all the pics I have:
