I added body molding strips between the rows of holes on the corn drum. This keeps the cutoff wheels from bouncing. One could also buy the new style double dimple drum, but that costs a lot more money. Next, if it has the shaft turning to drive the insecticide boxes, cut the shaft so it only drives the seed drum. Some are configured differently and use a separate drive, but at any rate, reduce the resistance that turns the drum so it's nice and steady. Then make sure there is no flopping of the seed tubes, get a nice steady shot to the row unit. Run low air pressure to the seed doesn't ricochet in the tubes. Probably a few other tricks that I've done over the years that I've forgotten about. |
