After an extensive search for some NOS and used ones I came up empty handed

I then had to go to plan B which was trying to repair the old wheels. I found some industrial rubber sealant and bought a couple tubes then filled the inside of the hollow tires and the outer cracks.
I used the sulky for about 15 minutes and the repair seems to be holding up

If anyone has some wheels they want to part with please let me know as I would love to have a spare set on hand. They are 14x2.75 with a 5/8'' bore.
Sorry for the poor quality of the video, It was pretty hard steering one handed with that front mount mower on.
I definitely got my exercise today
