Wouldn't worry about the tires. Those are R4 (industrial) tires. Pretty easy on turf. Even wetter ground will not leave bar marks like an R1 ag tread.
If you have hills, keep your hand close to the 4wd switch. Little help from the front will keep you from spinning out and leaving a skid mark. Be sure to pull it out of 4wd for going around trees and making sharp turns. The fronts will tear the turf more when engaged while turning.
Nice setup. There's a school in our area running the same setup with no issues.
