I just bought a used 2005 eXmark Metro 36" belt drive walk behind.
My plan is to change the drive wheel tires with the new ones that I just bought. Looking for details on how to do the job.
From the photos that I was able to pull up on Google, it appears that all you would need to do is pull the plastic center cap covering the end of the axle where there should be a "C"-clip that you remove. After the C-clip is removed via a pair of ring pliers, the wheel should pull right off of the axle.
Did you get both the tires and rims or just the tires?
If only the tires it can be a barrel of fun to get the old ones off and the new ones on the rims. An extra pair of hand comes in handy when prying the tires off the rim and putting new ones on. Also if they are tubeless it can be a bit of a trick to get them first seated on the sidewall beads to hold air. I use a ratchet strap around the tire to pull the center of it in toward the rim. This helps to flare out the sidewall to help set the bead so they will take air. Only put a couple pounds in, then take off the strap and air up to full pressure.
