Came off a functional 300a planet junior seeder. Front wheel gear cover guard with part number K721. Found seeder behind a garage under a tarp, so has some rust which i brass wire wheeled to reveal part number/markings/condition. The unit was rusty from being outdoors, but I was able to remove all hardware easily. Last picture shows assembled unit as found and is for reference only. I will be disassembling the entire unit, so if you need a specific part please contact me. Please see pictures for complete detail of overall quality, features, and markings.
