Need new tracks for JD 333D

[kwbretired]

I have a 2013 John Deere skid steer that is in great need of new tracks. I live in north central Arkansas with lots of rocks. My question is what would be the best kind of tracks for this environment excluding metal tracks $$$$$.

I got a line on a used set of tracks but don’t know if they will fit my JD 333d. The numbers on my tracks are 450 - 86 - 56 and the set I’m looking at is 450 - 86 - 59. Don’t know what 56 & 59 represents. Anyone has any idea if they will fit or what the numbers represents.
