Yesterday I did a rough calibration for fescue and was going to drill my yard. When first lowering the drill I noticed the openers were not touching the ground and I could not lower them with the handwheels. Also some of the hoses for the back box were pinched under structure. I returned the drill to the shop as I was sure I had an assembly problem. I removed the front weight plates and the rear plate used for a step. This just opens the area so you can see and access everything. When you remove the rear plate you can step over the basket and use it for a seat when tightening all of the loose hardware.
The disc openers down pressure spring assembly attaches to a rotating square rod as does the handweel assemblies for raising/lowering the disc openers. I started trying to rationalize the correct way to install the brackets that hold the assembly to the square rod. It turns out that because of universal bracket arms there were tons of combinations, but only one would truly work. I could not find a suitable pic of the assy, this was when I reached out to the forum. This AM Kev sent pics which showed me the definitive and correct way to mount the brackets to the bar.
After looking at the way it was factory installed, the disc openers and handwheel assemblies were actually fighting each other causing binding, not allowing the openers to raise/lower. So, I removed all of the opener brackets, then set the handwheels at midpoint of their travel, and re-installed the opener brackets CORRECTLY using Kev's pic. Now the openers raise/lower as they should.
Now that the drill raise/lowers correctly, and I had the rear of the openers disconnected I decided I would check coulter and opener alignment. Wow, some were decent and some were over an inch off. I began alignment by setting the coulter spacing across the toolbar and found most bolts just above finger tight. Then I aligned the openers using a 4' lever jammed against the last vertical inch of the coulter, extending to the opener. The front of most opener brackets had to be tweeked and some were majorly off. The bolts for the opener bracket were also not what I call tight. once the front was loose, then the down pressure spring brackets were loose I aligned the openers/coulters and re-tightened bolts. Now the proof is in the pudding on how good my alignment actually is when this rain stops, we dry out a little and I can pull the drill to check alignment.
I noticed that some of my hoses just didn't look right. I found out they were mixed up, some rear on front and vice versa. I also found the little red nozzle that comes out of the seed cup will rotate 360 degrees. By rotating you can make the hose come off the seed cup with natural flow which should help prevent clogs and prevent stress on the hoses.
Tomorrow I hope to finish up and wait for the ground to dry out a little so I can verify my coulter/opener alignment and then play a little. Thanks again to Kev for the pics, and to everyone else on this forum for sharing the good and the bad.
