Used farm equipment can be purchased at farm auctions, through farm equipment dealers (especially tractors), or found through website listings such as Craigslist or tractorhouse.com. For tractors, combines or other powered equipment the number of hours on the unit is a consideration.
No problem, Beth! A general rule to follow for a follow-up email to an application is to send it between three to five days after you submit the application. You want to give them enough time to receive and possibly review your information.
However, if you have sent in an application one option you have is to follow-up to confirm that the application was received and accessed. If you directed it to a person by email you can add a note in the message asking for a confirmation that the application was received and that they were able to access the content.
