There is no way under the sun you should own equipment to put up hay on 40 acres. Look around at neighboring full time ranches and you will see most of them hire their hay baled or have it baled on shares. You don't need all the hay anyhow so why not let someone do it for half the hay. The very best and well educated rancher in Tx can run 40 cows on 40 acres and that is exceptional. The average rancher run's 8 mother cows on 40 acres. I doupt it's much different in Fl. I hate conterdicting but you only need 1 tractor for all jobs on your place. I 100% agree that a Ford 3000,4000 or 5000 or equvalant is ideal (4000 being the most ideal). I 100% agree a FEL is indespensible but might not handle the largest bale in the country but it will handle 90% of them. To be prepared for the heaviest bale that come's your way,buy a 3 point hay spear or better still,a bale lift with 2 arms that do double duty for moving things too heavy for the FEL. The iceing on the cake,if you first put a bale on the 3 point,you can lift the heaviest bale in the country. As far as mowing,if grass is choking the engine down,move over and take 1/2 width of deck. Once cows are on the ground,it will never get too tall to mow. If you must ask advice on the net,I recommend inlisting the help of an experienced neighbor to look at tractors with you. Paying an experienced person $200 to broker for you is the best money you will spend. If you must wing it alone,buying from an established dealer is what I recommend. If you haven't turned wrenches,buy something much newer than the thousand series Ford. Good luck with your new place,keep posting as you get rolling.
