| Currently using 2630 screen, jd rate controller and a pwm valve to apply starter fertilizer, we hove 3000 psi hydraulic pressure prior to the pwm valve and 500 coming out or going to hydraulic driven pump, we cannot change flow or rate of the starter, have tested voltage and even replace the pwm valve, have change set up configuration numbers but nothing seems to change flow rate, the hydraulic pump just stays the same speed. What do we have wrong? | |
