We have recently gotten into the fertilizing side of the business, and filled the tanks tonight for the first time. To answer any questions before I continue, we are licensed and insured. Well, we began to get the liquid out of the tank and put it into our truck tanks. This was done with a HAND PUMP! Talk about taking forever - whew! I know that there is a pump available that will suck the fertilizer out of the tank and into the tank on the truck, possibly even one with a digital readout. Does anyone know where I can find a pump that will do this, or have a picture or explanation of how you do it? It takes way to long doing that with a hand pump, and we are running a 1/2 rate of nitrgoen this round. I can only imagine what will happen when we have to do a 3/4 rate or 1 lb. rate. Thanks in advance for any help or suggestions that you may have.
