Post your serial number, someone will have the correct year.
Pretty good looking old D6, they are quite a machine. Mine has also been converted to elec. start.

Looks like a D6B to me, they started in late 1959 and were very good machines should have a ser. no on it 44A????
The tractor is 1952 and the engine is 1956 but still looks like a D6B seat
Serial # on tractor 9U10709
Serial # on engine 9U23310
Also, I have been searching the net and am looking for a service manual. Can anyone point me in the right direction?

Either the engine has been changed or the rear housing has been changed. Yes I would order parts for the engine by the number on the block.
Ebay is the place to get manuals. I have about a full set for mine and thats where I got 'em.
Here is a page on the other board with D6 serial numbers.

PS - Welcome from one Texan to another....😊
Here is a link to an operator manual. This is one that you need, and was the hardest one for me to find. It shows what oil, how much and where, grease points, adjustments, maintenence, etc.

I have the operators manual, but there has to be a more in depth technical manual. You know, like the old Chilton manuals.
What years are inter-changeable with mine?
