Finger Pickup Metering Unit Operating Characteristics

IMPORTANT: The graph shows the performance characteristics of the Finger Pickup Metering Unit relative to operating speed. An increase in operating speed above the maximum speed will cause an increase in the population. The population is shown as a band on the graph since slight variations in population may result from differences in seed size and shape.

The most accurate population will be obtained when the planter is operated between one-half the maximum speed and full maximum speed. Planting too fast may result in doubles and triples and planting too slow may result in skips.

The maximum speeds shown in the planting rate charts are for optimum conditions. Slower speeds should always be used when planting in rough seedbeds to insure satisfactory planter performance. Poor depth control and erratic seed spacing may result from planting too fast for conditions.

See CHANGING PLANTING RATE SPROCKET COMBINATIONS in this section for instructions on setting sprockets for the desired planting rate.
