Replacement casters for a Honda HRC-7013 commercial mower 4.10-3.5/5

[Roc585]

Looking for casters for a Honda HRC-7013 36" commercial mower.

I've found the tires online: 4.10-3.5/5

But I can't change tires myself and I figured I'd try to find the tires and rims together with new bearings.

I've found casters at Tractor Supply, but my bearing hole is 3/4" and theirs are only 5/8".

Anyone have any numbers or links I could look up.

I think the mower is made by "Bunton"

Is this what I'm looking for? Will this fit my mower?

These are way cheaper than the John Deere casters.

They are "Marathon Tires Pneumatic Tire — 3/4in. Bore, 11 x 4.00–5in"

Just got them. They fit, but they're maybe an inch smaller in diameter. Also they don't have bearings, they have bushings. So not great, not perfect, but gives me time to take the original tires in to get repaired at my leisure.
