Just go after it with your FEL. If you mess up you can fix it. It's just dirt. With practice you'll become confident. I've become fairly decent dumping with the front of the bucket low to the ground going forward so it smooths the dirt as I'm moving. Then back drag in float with the bucket curled up or where you need it. My wife has become very good at smoothing dirt with the FEL just by doing it.I stopped by my local Kubota dealer today just to see if they rented box blades. They don’t. But they do rent York rakes for the 3-point hitch. Not sure if I should consider that. I’m definitely going to wait until we get some drier weather. I bought a couple of big tarps from Harbor Freight to cover the soil (I think we are getting more rain on Monday).
