Looking for some old tractor tools/attachments for my tractors

I am a younger teenager who loves antique tractors and other old equipment like that. I have a 1949 John Deere B, a 1946 Ford 2N, and a 1938 Case RC. I love driving my tractors around, but would love to have something to hook up to them and use just for fun. I don't have a lot of money to spend since I have most of it into my tractors, so I'm not looking for something really nice or expensive, just some older cheap tool/attachment that I could maybe work on a bit. If anyone has something like that, please text (360) - 603 - 17onefour. I'm only 13 so I can't take phone calls. Thank you.
