With 47 acres I would go bigger.
Many of us here have tractors similar to the
L2800 on properties about 10% the size of yours and don't regret it.
I suppose it depends on what you want to do though. If you own 47 acres, but only want to deal with a couple of them, and let the rest in the natural state that would be one thing. If you want to improve and work most of your property in one way or another that is another thing.
<font color="blue"> What is that the
L2800 can't do that the
L3400 could? </font>
The bigger tractor will just do more faster than the little tractor. But it will also do more slowly. I mean, it will have more pull, more lift on the loader, and so on IF YOU NEED IT. Maybe you won't need it.
But is seems to me that once we get our tractors, we find that more is usually better when it comes to working them. You WILL find ways to work the tractor you buy if you intend to utilize those 47 acres I bet...
That being said, every tractor is a worker and will work many times harder than you would by yourself. You will not be sorry regardless of what you buy. The key is to match your needs with your first purchase, and to avoid having to do it a second time, which costs a bit extra.
Good luck in your decision to either keep what you ordered or change to something bigger.
If it were me...I would go bigger rather than smaller...
