How to Use Liquid Fertilizer Rate Charts

1. Select the chart with the desired row spacing, hose size and rate range.

The REGULAR RATE hoses are standard on the metering pump. LOW RATE hoses may be purchased through your John Deere dealer.

A LOWER RATE will require you to use the LOW RANGE CHART. The driver gear must be the 14-tooth gear and the driven gear must be the 28-tooth gear.

A HIGHER RATE will require you to use the HIGH RATE CHART. The driver gear must be the 28-tooth gear and the driven gear must be the 14-tooth gear.

Refer to CHANGING FERTILIZER DRIVER AND DRIVEN GEAR COMBINATIONS for location of these gears.

2. Locate the desired rate under the TRAVEL SPEED column at the expected planting seed.

Determine the correct fertilizer transmission sprocket combination. Refer to CHANGING FERTILIZER SPROCKET COMBINATION.

NOTE: The rate charts are affected by many factors. Drive wheel slippage, the material that is being used and it's temperature, travel speed and pump hose tension are a few of the many factors which can affect this rate and, therefore, these charts should only be used as a guide. To be certain you are getting the desired rate, you must do a field check. Refer to CHECKING FERTILIZER RATES for instructions on how to check fertilizer rates.
