[QUOTE="SilliamWhale, post: 1752806, member: 1232"] Triple discs are capable of getting seed in the ground like any other. There are thousands of them in the world, they disturb more soil than to get them to work but they will yield a crop like any other. I find them unwieldy and less compact - a worn triple disc is no fun either. I think triple discs are basically about getting a double disc coulter without any downpressure to work better. Double discs same. Some good double disc drills about. For a 750 spiked closing wheels are better than smooth but not sure its the case for other drills especially if they move more soil anyway making it easier to get the seed to soil contact with the fractured soil that coulters have moved. Especially if rolled after. For very low disturbance drills seed firming is more important than slot closing but luckily you can do both. Where you are doing more disturbance (triple disc, tines) I doubt the advantage is as great as you have fractured soil to put on top to ensure seed to soil contact. None of these factors will make a better or poorer yield providing you have the plants you want/need and so no direct drill manufacturer is able to say that their drill is the one that gives a higher yield than others. And by and large they are all capable of seeding enough of the plants you want (none of them are probably sub 85-90% in terms of seed establishment nowadays which is enough). If they weren't capable the drills wouldn't be sold or purchased. If you get the plant stand you need then that is enough you won't always know the right amount to seed or the right time to seed unless hindsight, all drills can do this now and the obsession with blogging on trials is mildly interesting but it won't demonstrate much really. I like low disturbance because of the other benefits it brings to the soil and system but that doesn't mean my drill is high yielding drill, it means it makes my soil better and more resilient for each year which is from where yield comes, not the colour of the metal in the field. Anyway to stop this all getting to narky I suggest we leave this all where it is, we disagree strongly but there is no point getting too excited about it. [/QUOTE]
