It doesn't matter how big the machine, the key to good loader work is finesse and time behind the wheel. They look like a brute force tool but they are not. Find a spot where it won't matter if you tear things up a bit and practice scraping up soil and putting it into a pile. You will have better luck taking small bites and scraping over a distance rather than digging a hunk out of the ground. If (I mean when!) you do dig a hunk out, back up and refill the spot before continuing. To start, place the bucket flat onto the ground, tip it down a couple of degrees, begin moving forward. As soon as you feel the bucket cut into the ground, level the bucket out while continuing forward. If done correctly, you should have a small drop onto a flat piece of dirt. If you find your tires spinning too much or the tractor stops moving forward, then you should take thinner cuts.
Once you have a nice pile, put the dirt back and smooth it out with the loader. This will give you some practice using both downforce, bucket angle, and the float position.
If you don't have a spot that you can dig, then buy a load of soil. Practice spreading it out then picking it back up. With a little practice, you will be able to pick the dirt up off of grass without tearing up the grass (much!)
