NW Washington | Put a good easy see mark on the plates and then measure the distance you have to pull the planter to get the plate to rotate one turn. Then the distance you have gone divided by the number of holes in the plate will give you the plant or hill spacing in the row. Once you have figured this out you can adjust the gear ratios or plates to get the stand you want. Plate holes or notches needs to match you seed size. The number of holes and the planter/plate drive ratio are going to be related. The gadgets that push the seed out of the plate holes has to be working right too, seems like they are called "knockers."
Plate planters are kinda ancient history these days, but the basic are the same as with the new vacuum planters. You just have to drive slower. | |
