F3 with 16ft head.

So I just bought an 103 spra coupe from a guy. Great shape and low hrs by the way. and when I was loading it on my trailer I was telling him I was just getting equipment together to start farming. He asked what type of equipment I needed still. As a told him he said well I do have a gleaner up on the hill with my other equipment if I wanted to take a look at it I sure could. He said I haven't used it in four seasons and would hate if it just went to waste.  He couldn't remember the model . So we went up the hill and as we pulled up to it I could tell it wasn't used much.  I got out of the truck and walked around it. Every sprocket looked like new. I climbed up the ladder to check the engine out. It looked new. Same with the 16ft head. I climbed in the cab. It was very nice and the hrs meter said 598 hrs. I looked at the guy and said those are actual hrs aren't they. He said yes sir. He got it from the guy who bought it new with 201 hrs on it. I asked him how long it has been out side and he said  four years. But he started it two years ago and fired right off. As a new guy starting out. It's perfect for me and the price was so low I couldn't get my money out fast enough. Now I need to get it home.  About how many acres do you think an f3 can reasonably handle in wheat. Soybean. And corn? I am absolutely new to farming.
