Is this an unusual direct electric start conversion?

Yes, it is an unusual conversion. Normally the pony and transmission is removed and replaced with direct electric start.

Having the transmission still allows for two speed operation but your still stuck with the old clutch/pinion release mechanism.

Hi, Mineoladavid and Old Magnet.
That direct electric start system is not the only unusual thing about that '1965' D7, methinks. I suspect there are quite a lot of things in those photos that don't quite match '1965' - - - - - if you get my drift. Spoked front idlers, no turbo, apparent LeTourneau blade, - - - - - - should I go on?

A curious mind would like to know.

Link doesn't work for me, like to see it though, sounds shade tree or red neck whichever you prefer

Yes, link did not work for me either, had to look it up.
Try this one. Plenty of modifications as Deas noted.

well, seeing is believing. The guy has plumbing talent, could have just blocked off the pony passages though. Wonder how all that works? Just turn on the starter thru an on off switch instead of the normal spring loaded switch then go engage the old bendix and clutch? Shot of starting fluid and off we go. Thanks for the link Old Mag

Yes, I'd guess that is the procedure.....as apposed to pre-engaging the clutch and drive then Bang the starter runs up to full amperage rpm and the drive sleeve and latches wind up in the bottom of the flywheel housing.

Looks like a 3T or older with what resembles an AC hard nose.

Think your right. It would have to be a 47/48A to be a 1965 model.

I took another look at the pictures. Looking at the mainframe, just below the starter, it has to be a 7M, 4T or a very early 3T.

They beefed up the mainframe at around 3T 1200 to maybe 1500, somewhere around there.
