CAN I STILL FARM WITH A FARMALL H?

Hi i am 17 and i am going to get into the cattle business within the next 5 years for a side job approximately 25 to 30 acre piece of property to raise about 15 cattle and the rest use for hay and forge making. i have bought a lot of equipment in the last year so when i get the farm i can get right to work. I have a Farmall A and a H, two 2 bottom trailer plows, 2 manure spreaders, a drag, a 2 row corn planter and a 5 foot bush hog for mowing pastures and making hay and a set of cultivators. i still have to get a hay rake and a baler but everything else i have to get stated. All of my equipment is either refurbished or is in good working condition. i am only doing what i can afford and the equipment i am buying may be old but it still works and its all i can afford right now. can i still use this stuff in a small operation like mentioned above?
