I have had a lot of requests with my surprisingly popular antique tractor series. I have been having trouble keeping track of them, so, inspired by PlanesOfOld's custom boat requests, I have opened a custom tractor request outlet. You can request tractors here.
RULES
1. They MUST be real tractors. Made-up tractors will not be created.
2. They must have at least 100 remaining examples in real life so there are pictures online. I guess you could request one with less if there is artwork of them. This one is at my final discretion.
3. Requests for a series of tractors get bottom priority. Series get lowest priority because I'll build each tractor separately and I'll just build them in between requests. Implements and attachments may be requested, but will be placed on low priority. Modern tractors will be made when I feel like it.
4. NO FARMALLS! (just kidding, I don't care. Go ahead.)

PREFERENCES
1. I would prefer antique tractors. Generally they are easier to build (look at a 48 G JD versus the latest model) and I know more about them. Modern tractors will be placed on medium-low priority.
2. I would prefer American tractors. I'll do a Chamberlain or a Lanz if you want one, but I'd rather do one that I've seen in real life.
3. I would prefer TheOldColonel or any of his numerous alt accounts not make any requests at this time.

To drive the tractor I created to justify posting, just throttle up to 75-100% and use yaw to steer. You can drop the implement with ACT-1, but I don't recommend it as it makes the tractor very difficult to control.
