Help-regarding Facebook ads campaign

Can someone help me to tell me how to set a Facebook ads campaign for selling agriculture machinerys for small farmers?
#people whom are interest about tractors, farms, agriculture
#people whom are living in rural areas
#mens between 18-65 age
It's ok?
Please add more ideas.
Also maybe someone can help with some advices about a Google adwords campaign or any other types of paid advertising or unpaid regarding selling agriculture machinerys.

The only way you are going to find out is to actually test it.

Set up a campaign and test different audiences. Your targeting strategy sounds pretty good so far. Make sure you track everything (Facebook pixel) to find out how much you pay per conversion.
