CAUTION: To help prevent serious injury or death to you or others caused by
unexpected movement, service machine on a level surface. Lower machine to ground
or sufficiently lock or block raised machine before servicing. If machine is connected
to tractor, engage parking brake and place transmission in "PARK", shut off engine
and remove key. If machine is detached from tractor, block wheels and use shop
stands to prevent movement.

CAUTION: Do not clean, lubricate, or adjust machine while in motion.

Use grease based on NLGI consistency numbers and the expected air temperature range during
the service interval.
Use a multi-purpose lithium, water resistant, moderate speed, and NLGI grade #2 grease.
Other greases may be used if they meet the following NLGI Performance Classification: GC-LB

IMPORTANT: Some types of grease thickener are not compatible with others. Consult your

grease supplier before mixing different types of grease.

LIQUID FERTILIZER APPLICATION RATE AND PRESSURE CHART

TABLES ARE BASED ON 30” NOZZLE SPACING

Values in this chart area based on using water. To calculate nozzle size required for your fertilizer application, the weight of the fertilizer solution
must be accounted for by using a conversion factor for specific gravity. The Conversion factor for 28% liquid nitrogen is 1.13. Example: desired
rate of application is 10 GPA of 28% N multiply 10 gallons per acre of fertilizer you want to apply x the conversion factor for 28% N (1.13) to get an
equivalent rate for water. 10 x 1.13 refers to the chart for 11.13 gallons per acre at your desired speed/MPH.

GPA = 5940 X GPM H20 = WATER SOLUTION
(Per Nozzle) MPH X W GPA = GALLON PER ACRE 28% = H20/1.13

GPM = GALLON PER MINUTES 32% = H20/1.15

MPH = MILES PER HOUR

W = WIDTH

This table is a reference only. Please calibrate your equipment to insure proper rate of application.

The information contained in this issue is offered in good faith by Yetter Mfg. Co. to further the understanding of liquid fertilizer
application.
