Happy to post something about the tractor this time.  I don't think I had mentioned earlier that when we brought home the H it was missing the hydraulic pump.  The pump is a big self contained cast iron unit that fits into the belly of the tractor and is powered by a coupler that attaches to the counter shaft.  Not long after initially getting the tractor home I found some pictures from the web and sent them to cousin Renae and asked that if she came across something that looked like the picture to let me know.  Well, they are selling the farm and in the process of cleaning things out she came across the pump in a shed.  I was ecstatic!  I have no idea why it was removed or if it even works but at least now there won't be a big gaping hole in the tractor where it goes.  It probably weighs 75lbs or so and moving it around was pretty fun.  It was missing the lever that engages it, the rod that is used to move the lever from the tractor seat and the coupler to power it.  Thank heavens for ebay - found them all and they arrived is short order. 

Here's the pump itself.  The lever on the right was purchased from ebay.

The round slotted part on the front of the pump is where the coupler attaches to power it.

The coupler and the rod to move the lever in the above pic.  More ebay finds.

The counter shaft where the coupler attaches.  This is from the web.

I didn't feel like crawling under the tractor and taking a picture so I found this one on the web so you can see where the couple attaches.
