If you are concerned about hills and stability, then be sure to step back a little and take a look at the footprint of the tractor (with dealer with you).  He should talk with you about the wheel rim options and ballast options.  We have hills.  I was concerned about that.  I selected a wide footprint.  That and ballast may help a lot.  Also. unless you are only needed to mow acreage, I would be careful buying a tractor HP based on having only 2 acres. especially doing rock - loader - road maintaining work.  Best wishes, Larry
