Does it have guards front and back? If not, then get something in place.
Does it have a slip clutch or shear bolts? If it has a slip clutch, go over the maintenance schedule. If it has shear bolts, buy extras to have on hand.
It's not if you will break a shear bolt, it's how many you will break. Lastly,
but the most important thing. When I bought mine the dealer told me it will throw a rock 250 ft with enough force to penetrate wood. Remember that when people are around. I'm a relative newbie as well, but when they chuck stuff, it's not like a walk behind lawnmower.
Happy mowing...
