Hows your magnetism????is coil no. 3 activated????if not you have a power , or grnd, or connection isssue. Clean your connector on the valvestack, spray it dow with a good penetrating oil.Also if your reel raises and lowers fine you might have a switch issue???now if you have magnitism at coil no.3, you probably have a o-ring rolled on the manual drop rate poppet, poppet in question is above the 1/4"bolt on the bottom of the raise lower valve, please note that o-ring material can get stuck in the seat under the no.3 hyd .stem. If you are going to work on the hyd. system make sure the feederhouse is down with pressure released.the kit to repair valve is a ah151400.
thanks for the tips. did you read the question about the oil pressure warning light. the engine has pressure but the light will not go off. when i put this machine to rest last fall after harvest, everything was working fine! any suggestions are appreciated.
Did you add hydraulic oil in tank before cranking. If you bust a line or leaks out and you add oil, sometimes there is an air lock and you have to press the charge pressure fitting right above the electrical control bank with motor idling till you get oil out of the little insert in center of fitting. This lets the air out and then hydraulics work normal.
