Posted 5/18/2017 22:20 (#6024165) Subject: hyd drive acting up when oil is hot
using an Integra with hyd seed rate control and it has been working ok last year and at start of season.
The last 2 days after about 2 hours of planting population (and hyd drive) goes up then quickly goes down and takes a while to settle down.
we think it is releated to the hyd oil temperature which was fairly high the last 2 days
we are adjusting the pwm gain and it has helped.
also when stopping to reload more seed and oil had a chance to cool down. problem was a lot better.
