Ethan, at a glace maybe. From the 660-PUP to the Cubette to the numbered prototypes the frame stayed fairly consistent. The tractor that Matt posted photos of is quite different if you study it. Here's a couple photos of the 660-PUP proto, one of the actual Cubette, one of Tim Delooza's reproduction Cubette and finally prototype #409. All used a Farmall Cub transmission.
I really thought it was a Clinton engine. Oh well, my memory isn't what it used to be, lol. Made a lot of progress cleaning up the backyard today. 1200 did just fine pulling my 4x8 trailer full of brush. I love the reciever mount from Mike M. In Elgin, won it a couple years ago at a PD. Let's me use an extended hitch for tire clearance when turning and backing. I can think about a cub shed now.
So I got to my 149 tonight and fastened the throttle cable out of the way of the lift cylinder,but I found something which I found odd,a safety switch above the key switch inside the steering tower which seems to have something to do with the pto lever.it looks much like the start safety switch that’s actuated by the brake pedal.so here’s the question,is that factory and option or a PO add on?
