Two tractors are preferable to one in most cases. You need one 60+ HP and one 30- HP so you can get to all places and lift large loads when needed. I prefer to have FEL on both. I use my LS to move large loads, push over trees, pull up stumps, bushhog pasture, till up the garden with 72" tiller and disk up pasture for reseeding. I use my Kubota TLB for digging, all kinds of digging like stumps, dead standing trees, rocks, burial plots for animals and moving small amounts of dirt when I need to fill in some small holes in the yard. It is light enough so it doesn't damage the grass.
AND lets not forget to have the second tractor to pull out the one that is stuck, BTDT.
