Gregory, Thanks for your questions on our video. This is Eric Watson…I am the one in the video. To address your questions… Setting the planting depth: I always suggest working from the front to the back. Set your coulter depth first. Then focus on your seed depth. Your coulter depth is controlled by the single point depth stop valve located directly behind the gearbox on the drill shown in this video. Coulter Depth: Generally on a drill with a “frame mounted coulter” such as this model…you will run the coulter ¼ to ½ inch deeper than your seed depth. The reason you seen the comment on the other video about running the coulter depth ¼ inch shallower than the seed depth…this is a normal practice on a “Unit Mounted” coulter. Meaning the coulter is mounted directly, on the front of the opener frame itself…rather than to the actual frame of the drill. We want the “Unit Mounted” coulters to be shallower, so that you’re not taking away as much down pressure or force from the row unit itself. Once you have the coulter depth properly set…then turn your focus on the seed depth. This is adjusted by moving the “T-Handle” on the back of the opener frame. When you have the seed depth properly set…you need to double check that the drill is still running level in the lowered or planting position in your field. You can place a carpenters level on the lid of the seed box to check this. I hope all this helps you better understand your drill and how to properly set it for the best results. Feel free to reach out to me if you have further questions on this. Thanks, Eric Watson
Great video! I have a new Great Plains 706NT that I just started using this year. I have questions about setting the planting depth and how to measure the actual seeding depth in the field. SETTING PLANTING DEPTH: Once the drill is hitched up level, what sequence of steps should I take to set the depth? Do I (i) first get the opener depth set with the T-handles and, once it is correct as confirmed in the field, (ii) make sure that the coulters are 1/4" to 1/2" deeper as you recommend, and (iii) if the openers need adjustment, move the coulters up or down as needed by turning the knob by the gearbox?. Another TH-cam video about Great Plains no till drills recommends that the coulters be 1/4" higher/shallower than the openers; whereas, you recommend that the coulters be deeper than the openers by 1/4" to 1/2". The other video says that if the coulters are deeper than the openers, some seeds will fall into the coulter trench and be too deep. Frankly, this makes sense to me. Why do you recommend that the coulters be deeper than the openers? MEASURING SEED DEPTH: When I'm in the field planting a test area to ensure I am planting at the correct depth, where exactly do I measure the seed depth? In particular, do I measure (i) between the seed and the top of the soil immediately above it where the press wheel rolled over it or (ii) between the seed and the higher soil on the sides of where the press wheel rolled over the seed? Your advice would be greatly appreciated. Thank you!
