To each is own but I think you will be really disappointed with the capabilities of that tractor with undersized turfs and not loading them.
Our JD 2040 has ags that are loaded and about the equivellent tread of turfs. It wont getout of its own way. It will literally get stuck on a wet leaf with Just the weight of the loader, let alone putting anything in it.
If you go the route you are planning, I dont think that blade will you much good. Because when you drop it to the ground, you have absolutly no added weight to the rear, and turfs to boot. Unless you have a way of removing the loader, I dont think you will be able to move much dirt/gravel. And with a bucket load of wood, I think you will be fighting it more than you want, especiall trying to back up.
If possible, and you really want the turfs, I'd look for a set of rims. That way, if you are unhappy with the performance, you can throw your old tires back on. If you decide you can live with them, sell your old tires/wheels then.
