Low-Rate Sorghum1

Before assembling the low-rate metering unit, you must determine the size of the seed. You can accomplish this by using a seed sizing kit, available from your John Deere dealer.

NOTE: The three washer shims must be used with the low-rate feed cup. Do not operate without all three shims.

If the seed being planted will pass through the 3 mm (9/64 in.) screen by shaking vigorously, use three washer shims (C) between feed cup (B) and housing (A) only.
