I have a Gleaner G I am going through, greasing oiling and adjusting. I am completely new to combines, but have the original owner's manual on adjusting everything so going through it is not a problem, just a function of time. The combine is is very good condition, little wear on sprockets, etc, belts in nice shape. What I need to know is the dimensions of the header jacks (feet for parking the header.) They are missing. I need the length of each one, the distance from the top to the holes for the pins. One hole locates the raised position, the other the parking position. I will have no trouble fabricating them as I have a complete machine shop. I also cannot find any information on a lever in the cab. It is not listed or shown in the the Owner's manual. I think it may be a high-low range selector for the transmission. It is just above floor level on the right side of the seat. Following the linkage takes me to the tranny or differential, not sure which as I haven't been under the combine yet. I didn't notice the lever when I drove the machine home a couple of months ago or I would have checked it out. Any help would be appreciated.
