The year is really not important to value. They were all built about the same, and were not built as a model year like cars. You have a Super A.
Price depends a lot on the area of the country.
In poor condition in a low-price area, $500 to $1200. In good condition in a pricey part of the country, $1500 to $3500. Poor areas are where population is low and there are lots of that model available. Pricey areas are where there are lots of potential buyers (5a suburbs) and there are fewer tractors. For instance Arkansas, lots of A's were sold and there is not much market for them. Eastern Connecticut, the reverse.
Implements don't add much to the value (although it makes no sense to me) except for rotary mowers.
Tell us your state and you can get a better idea.
