Congratulations and welcome to TBN from Downunder, Mate.
The first thing you do is to read the owners manual... all of it (maintenance schedules & procedures are in there). The second thing is to take your time and slowly get to know the functions of your tractor... If you've got a Front End Loader [FEL] keep the load low to the ground when moving from point A to B.
Have fun! Oh, and enjoy the site.
