[AJD] GP thoughts and comments, was: Where to find extensive information about the JD GP?

[kreig]

In regards to the GP's, I am interested in knowing more simply because I own 
one.  A 1930 GP in good running condition, needing a few parts here and 
there and not really knowing what parts are needed.  Have been looking at 
and comparing GP's at shows and my impression is that no two GP's were EVER 
built the same!!!

Seems there are about 4-5 ways to run the spark plug wires, about 10 
different configurations for air cleaners and exhaust.

I found an original tool box off a parts tractor and am finding they came in 
two versions, one with a large hole at the front and some without. In 
pictures i see some holes are empty while in other pics I see there is 
something attached.  In conversation this last weekend I was told the hole 
was made to accomodate the "dirty" end of the grease gun.  True???  There is 
a small hole on the top of the tool box and appears to have no function, no 
knob is seen in the parts catalog.

Never could figure out what kind of handle was needed to actuate the PTO. 
Some tractors have a non-removable 90 degree handle for the PTO while others 
seem to have a missing handle.  This last weekend I found the "correct" 
handle on a 1935 model and will make a reprodution for my 1930. This looks 
like part number #AC-573-R   Hope this is correct.  I also see in the parts 
catalog, number C-2118-R.    There are no part numbers on this handle.
At the show there was a 1930 GP next to mine with the 90 degree handle, go 
figure!!!

Also the radiator casting #C-257-R    seems to come in two versions, one 
with a bolt hole on the right side to attache the air cleaner and the same 
casting and casting number without this mounting hole.  Wondering why I have 
the mismatched set of air cleaner/radiator setup. Thinking if it is worth 
picking up a replacement radiator casting to make things "correct".

I was surprised to look through the owners/operators manual and there seems 
to be no mention how to operate the machine, how to activate the PTO or 
anything else, seemed rather strange.  Have never seen a GP with power lift 
and not sure what it is designed to do.

Ok, I guess that is enough in one posting.
