North Central Indiana | Just got back in from the field. Still no luck. It's not electrical because this planter has no solenoids like my 7200 did. Just straight hyd. I have the tech manual from JD and traced the hyd circuit and can't see how anything in the valve can prevent it from lifting. 1 check valve might cause problems, but took it out and seems to be ok. Possibly a lift cyl could be bypassing all the oil, I'll check in the morn. (thanks for the tip remmpork) Agrivates the he!! out of a guy, rain, rain, rain and then finally get some good weather and this crap happens. And to think I gave up a desk job for this! | |
