NH TC30 is just a toy compared to Zetor. For heavy use (abuse), Zetor is more forgiving tractor than you can imagine.
For cabbed tractor with 4WD and about 300hrs, price of Zetor is GIFT. For your size of property, Zetor seems more adequate than TC30 for me.
Only issue is higher centre of gravity and overall dimensions of Zetor compare to TC30.
Think once again before you spend your $$$. /forums/images/graemlins/wink.gif
