I really looked at the global loader attachment on the JD website. I couldn't figure out if the lower pin configuration was an electric over hydraulic or straight electric or straight hydraulic operator.
And the pin configuration appeared to be a likely source of frustration when using with ice, snow or that wonderful combination of ice, snow and mud (or throw in a little hay and manure into the whole mix). It seemed to me that getting the lower pins either in or out with those kinds of conditions would be a time of "blessing the implement" and thinking of ways you'd like to torture the engineers who designed it..
I have the SSQA and the neighbor has the SSQA on his JD 542 FEL. It works and it's real simple..
