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.
MAINTENANCE BEARING ASSEMBLY AND LUBRICATION NOTE: If you choose to leave the seal, then you need to fill the cavity with grease. If you choose to remove the seal, then you need to fill cavity and maintain the grease every 50 hours of use. Practice Safety Understand and practice safe service procedures before doing work. Follow ALL the operating, maintenance and safety information in the equipment operator manual.

MAINTENANCE Grease must fill this Hubcap cavity.
MAINTENANCE Lubrication 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.
MAINTENANCE Lubrication Symbols Lubricate with grease at hourly interval indicated on symbol.

TROUBLESHOOTING Problem Cause Solution Planter frame not set correctly. Ensure that in operation the planter frame is at correct height (20”-22”) and level. Planter opener blade worn. Replace planter opener blades. Cannot adjust coulter deep enough. Coulter blade worn too small. Replace coulter blade. Coulter will not penetrate. Lack of spring tension. Increase spring tension. Coulter penetrates too much. Excessive spring down pressure. Reduce spring tension. Seed placement is too deep.
TROUBLESHOOTING Cause Insufficient down pressure Solution Increase the tension of the planter unit down force springs Planter frame not level for and aft Level the frame at 20” frame height while in planting position Soil too hard/compacted May have to use a tillage implement to loosen soil Fertilizer coulter blade adjusted too deep Raise the coulters.
Our name Is getting known Just a few years ago, Yetter products were sold primarily to the Midwest only. Then we embarked on a program of expansion and moved into the East, the South, the West and now north into Canada. We’re even getting orders from as far away as Australia and Africa. So, when you buy Yetter products . . .you’re buying a name that’s recognized. A name that’s known and respected.
