Been through all of my service manuals, parts manuals, and operators manuals. Nothing describing this hole or what it is for. Heck, some of the pictures in my '68 operators manuals, don't even show the hole there. It wouldn't be for any of the attachments that I would know of, and the rear pto runs off of the same clutch switch as the front pto, so that is out of the question. I still say it was most likely a hole allowed for a cab mounted warning light or even cab mounted headlights, just in case you wanted to keep them independantly wired, and on separate switches just in case you wanted to remove the cab.

Troy, All my 140/120's have the rear PTO running off of the Hydro and not the front PTO. Was this an optional PTO?

No, you're right Brian. I had a brain fart. The rear pto is always turning, you engage the tiller drive with the tiller engagement lever.

I think he means the electric clutch on the rear PTO is controlled by the same switch as the from PTO.

 

Greasing the hydro control sounds like a good guess but I guess that isn't right.

 

Troy,

Do you have the service manual for the pre 30,000 models?

Thanks Troy, I only asked because you have seen a lot more of the rare options for JD's then I have.

Bobby , the electric clutch was only offered on the 300 Series and later. The 100 Series turned all the time as long as the Hydro pump was turning as the Rear PTO was coupled to the back of the pump.

I have service manuals for the 120's and the 140's, but I'll have to check to see if they cover all years and serial numbers. I just assumed they did, and never really looked to see if they are broken down to serial breaks. I'll let you know tomorrow afternoon.

Thanks, I got one set of the service manuals but they are they are for 30,001 and up. I think most of the info is the same but of course the rear axle items are different. Here are some screenshots from the JD 140 Hyd Op Manual:

The second pic of the two is of a later tractor as the engine is painted black.  That change took place in 1970...

 

Things that make me go "Hmmm...."

You can also tell that it is a later unit, as the clutch knob was revised to the toggle switch and the PTO light has been discontinued. The hood decals also have the black outline border, rather than the silver outline like used on the earlier 140's.

The 120 service manual does not have any pics that help with this mystery.  Part of me wonders if this is a hole that could be used to lubricate the hydrostat control handle as that pivot point is located right in line with the hole.  Still got me on this one...

I have a 1969 H-3 apart with the same hole. It gives you access to remove the pin that holds Hydro control lever inside the dash to the Hydro Control Shaft that goes thru the dash to the Speed control handle.

That's a Patio for sure. Back in the day it wasn't a popular option. Some dealers went so far to paint them green just to get them sold ! Two years ago I found just like yours painted green. Lucky for me no one else there new it was a Patio.  Nice score !

Thanks Sandburr! So far I'm having fun with it! After the garden gets planted I plan to do some work on it.
