Tree cart with dually wheels and tape the ball dig the hole to the tape roll it in ,If its to deep roll tree one side add dirt then roll tree to the other side of the hole add dirt stand tree up. Im old school I guess, Planted lots of trees that size 2.5-3''cal. over years. Not often I dig holes with a machine. Now if its a new lawn install and trees go in before the lawn is done I take my 2ft auger and dig the hole and hand spade sides off.
