I recently inherited an AC 1961 D10.  It has no battery in it and was wondering how to tell if it is a 6v or 12v.  

The tractor has been restored.  If I were to sell it, how much should I ask for it.

Thanks

You know this is one that I could have sold.  They originally came through with a 6 volt battery.  I would suggest you look at the generator.  Usually it they have converted it to a 12 volt there is an alternator instead of a generator. 
They were nice tractors.   
I have no idea what they are selling for.  You could check the hydrallics.  They could come through with two types.  One would be the pump would be on the rear of the differential.  The other is a live pump and would be on the right side of the engine facing front.  You would find a tank for the oil there.
Good Luck!

D-10 changed from 6 volt to 12 volt in 1961 with introduction of Ser. II at serial 3501, along with the 149 cu.in Engine.

Maybe take out a head light and see if the volts are stamped on it.

The D-10 series came 12 volts, also if it came 6 volts someone could have changed it to 12 volts.

Shouldn't hurt it any to put a 12v battery on it, no matter the setup.

My parts book shows beginning serial #9001. I think that was the beginning with series III.

Gary's information is correct. There were a number of changes to the D10/12 in mid-1961. The Series II decals came a little bit later. The 9001 serial number was the start of Series III.

There are three types of hydraulics on D10/12s. The early models had either the WD/CA piston type pump on the back of the tractor (not live) or a gear pump on the engine (live). With the mid-1961 changes the D10/12 got a gear type pump on the rear of the tractor which (along with the PTO) was driven through a quill shaft through the clutch, giving both live PTO and hydraulics. The engine mounted pump was also used for power steering (fairly rare).

I would really love to have a D 10. Only missing it and a D12 to complete my D series collection. Unfortunately, looks like you are quite a ways away from me, and if I give you an honest "what it's worth" price, it would be beyond what I can afford. Darrel
