The R2850R will fit the following: 24", 28" P Steel 3010, 28" cast spin-out 3020U
The R34810R will fit the following: 24" cast JD500, 3010 I, 26", 30" cast 4010-4020. Each weighs 115 lbs. May fit more but those are the ones I have for them.

I'll add to what MSD stated that the R34810 weight is listed in all the following parts catalogs.

I have the R34810 on my 60 std with 30 inch wheels. The weights were advertised as being for a standard tractor, so I bought them knowing they were not the same as the ones on my 70 std. They fit fine and even have the oval hole. Only an expert would know the difference.

I'd have to check the part number but if they are the ones with the large oval center and a flat outer face- they also work as a "converter" weight to put the 4020 flats on the heavy offset cast of the 4520-4850 wheel.
