South Georgia | No, sorry, but I've seen this every time I've had fertilizer in the tank. No agitation, boom sections off, the 6700 would deadhead at 115-120 psi with water at WOT, or about 140-150 psi with liquid fertilizer. The 3185 does exactly the same thing. I slow the pump down to make me feel a little better, otherwise I get a little nervous about getting too close to the limits of my 200 psi-rated plumbing.
At the same pump rpm, deadhead pressure is higher with fertilizer, everytime I've had any in the tank.
You may not see this, if Deere has a 'spray off' pressure, as you said.
