First things first. Did you wash the plow after last use? if so did it sit outside in freezing weather? Did you check the Hyd. oil level? If the springs on the wings have ice on/in them that can cause problems. The springs are normally extended to push the wings forward. If there is ice in there they will not compress very well when trying to retract wing. Did you change the Hyd. fluid this year? if there is any moisture in the system it can cause the solinoids to stick causing slow response times. You can add a couple of teaspoons of HEET or other brand methanol to your Hyd. oil to act as an anti icing agent. Just a couple of things to check. If you suspect icing... get it in doors for a couple of hours to thaw out. Hope this helps, Abbert55
