How much does one of those case complete single units cost?

I think that instead of making fun of your coemption you should focus on why your red drill doesn't work!!!!! mimic the trailing arm (Deere) where it excels and make something better and let your product speak for itself everything you have said is true. except that your drill needs HELP!!!!!! lets start with the parallel arms GREAT IDEA Depth adj that is simple and works well and solid, good work 18 inch disc is too small and wears out too fast your old drill had a 22 inch disc and was way better hyd adj down pressure awesome! seed tube cheap, simple, effective, and JUNK!!!!! You are shotgun blasting the seed into the trench!!!! if you dig behind the unit you will find seed scattered in the trench not in the bottom this needs looked at scraper ok lets be honest your scrapers are simple but expensive for what they are. Finicky and plug easily. they don't like wet conditions and if disc gets too small dirt will stick to it and shove it up in between scraper and blade. this is always a good time and is a great way to test your faith the scraper guard oddly important cause if they wear out the scraper will be plugged from above from straw or dirt or anything that could possibly fall in there bearing on the disc remarkably easy to change great design simple gauge wheel assembly, its a gauge wheel it works little black rubber flapper between disc and scraper plug up with mud also flip seed out of the ground. They ride well on the floor of the tractor cab and are easily removed with Milwaukee zippy. I'm wondering if they are your design to trap seed in trench kind of trying to control the blast press wheel I'm not sold I think there are aftermarket options that are better than your stock option for no till. this is for the green one as well precision 500 tow behind cart the drill frame has been very good and solid even after a few close brushes with power poles splinters flew drill survived cart I actually like the metering system delivery system even for milo and alfalfa I have been pleased very simple. these are my opinions only and my guess is you don't care and will never read it anyhow
