What is your budget?

My thoughts on the 2N:

The price is about average for a tractor like that. It is an old model tractor that won't have much horsepower, and only half of the PTO horsepower on those model tractors makes it to the ground. The age of the tractor also makes it harder and more expensive to find parts. So if you have a breakdown, you may be down for a while.

The original electric system on that tractor has also been converted. It was originally manufactured with a 6 volt system.
