Very popular storage concept back in the day when space is at a premium. It is easier than stacking them on top of each other.

Let me guess. The yard flooded and those big rear tires floated them all right up onto their noses?

Attached to the original photo. Not sure how all the numbered Cubs wound up on their noses.

If anyone would like to find out if their numbered Cub with flotation tires will float rear end up let me know. I have a pond.

I think I'll keep mine safely dry and on 4 wheels, but I'll bring a lawn chair if anyone else wants to give it a whirl.

Are you sure they were not trying to root those numbered Cubs, so they could grow them into full size Cubs!

Yep, that's exactly what must have happened, lot flooded. Here's some basic calcs

a 13.6 x 16 tire is 38.5inches in diameter and roughly 13.5 inches wide, taking out the 16 inch diameter for the rim, the volume is roughly 13,000 cubic inches, or 56 gallons, or in buoyant force, roughly 469 pounds of buoyant force per tire.

So, figure roughly 900 pounds of buoyant force on the back (given 2 rear tires) and a tractor that weighs just about 1,200 pounds, I'd say you end up with the tractor standing on it's nose! I'm just surprised that the water was slow moving and the tractors were steady enough to remain that way. If you look closely in the middle, there's another lo boy behind the others with the standard 9.3 x 24 tires on it, sitting normal. Very cool photo!

Yep, that's exactly what must have happened, lot flooded. Here's some basic calcs . . .

I took a different path to the same conclusion:

Tire fluid fill charts say 31 gallons for that size tire, 75% fill. That puts a full fill over 41 gallons, just for the air volume inside the tires. At 8+ pounds per gallon, you get 350# of buoyancy (31/.75x8.34). Times 2 for the pair gets you around 700#. To that, you add the volume of the tire material itself (another 15-20% ?) and all the volume of the rest of the back of the tractor (mainly 3 gear housings) and you are easily in a range where the back end would float, but well short of enough to float the whole tractor. If the front wheels hadn't remained on the ground, it is unlikely they would have remained lined up and spaced so evenly.
