 They made the articulating part in the center and got a Porsche 671 Detroit on it, which I drove them for ever. Really, there were a lot that you heard them all through the night. I mean, because they were so loud. Pretty interesting to have so much, you know, so much power back then. And like I said, this is probably the the last trackers were built in 71. And I'd say the first ones were probably built in the 50s. I'm pretty sure that might be that long of a span. Like I said, they're just two rear ends. The gears in the front one are turned around. And like I said, they've got a belt drive. They were a hauls back in the day. I guess I would say our first full drive was a 75-20. And it was probably purchased in the, I would say early 80s, probably more likely. And like I said, we had these and probably three regular trackers to go. And that's what we put 5,000 acres in with. And we were stretching them all the way from almost to too close to all the way down to Gregory. They self-propelled grain carts and they land planes, grain, I mean, just regular full-type grain carts. And oh, they're just just miles and miles of stuff that they actually did back in the day. Matter of fact, my grandfather built one of the first reversers for a header on a combine. And he worked a little bit trying to patent it. And I've seen some stuff on that. And it was a really interesting time. And he loved the river. And of course, he had houseboats on the river all the time. That was my enjoyable part of the day that me and him would take. And I'd be running one of these for, you know, several hours a day and he'd come get me an hour or so before sundown, we'd go out fishing.
