Hello all! I have an old Jacobsen G10 tractor that has the Ford industrial engine 172ci.  It has hydraulic 3 point lift and hydraulic plow on front.  Right now my question is about the pto.  It has the pto in the rear and a rod runs from that gearbox to another gearbox in the front which has another splined shaft that sticks back toward the engine, and it looks like it centers the engine crank pulley.  But there is nothing connected to the engine and I can't see if it's connected to the rearend any where.  Has anyone seen this or is all this stuff aftermarket?  There is one rod that the driver can push or pull that looks like it pushs a rod in and out of the front gearbox, this may engage and disengage this gearbox which is what actually turns the rear pto.  Does this sound right?  If so I am wondering how I am suppose to connect that front shaft to the engine.  It doesn't look like the pictures/diagrams in the manual on this site.  Any help would be appreciated and also any comments on the tractor in general based on what you see.  The pics attached will kinda show the things I speak about.  Thanks, Nathen.

Nathen welcome to GTtalk.  I'm not familiar with the Jacobsen setup but I'm sure someone will be along that will be able to help.  Over all your tractor looks pretty good.  As you may know we like pictures so we appreciate the attached pictures. :thumbs:

Thanks, it's quiting time so guess I'll check back in the morning.  I still have to get the engine running so I'm not in big rush anyway,  I guess I'm just making a list of things I'll have to fix before it's ready to use.

Okay, I'm attaching a couple more pictures of the front pto/engine area and one of the shaft at the rear.  Do you suppose there is suppose to be a shaft that bolts up to the engine pulley and slides onto the front pto shaft to make the connection?  That would explain the extra long bolts and extra nuts on the engine pulley like it is.  I just wish I could find someone somewhere with a picture of what all this is supposed to look like or if any of this pto setup is factory.

Thats what it looks like,, The long bolt was for a thick part thats missing that conects to the shaft,, Like a ujoint part cause there mite be movements from the motor an that why u mite need it,, If there is no movement up an down or side to side then it looks like u should be able to make the part for it easy if u had the yoke part for the shaft,,,, Hope this helps,,,

You are missing the driveshaft for sure !! That engine in an industrial tractor has a driveshaft running a hydraulic pump. this shaft has 2 rubber bushings connecting it , kind of similar to that found on mid 70's cub cadet hydros. and it also had the same on the other side as well to drive the pump or what ever it needed to drive, like a gearbox in your case.. Tisco may have what your looking for, as they have a lot of goodies for old Fords. Look up stuff in the Ford section under "801" series you may get lucky and find something that will work. Also it could be made with u-joints too so keep an open mind while searching . Good Luck , Keith

Would anyone be interested in this tractor or any parts off it or the engine?  I would part it out or sell whole at a good price.  I see parts from/for this engine on ebay for really high prices, I can sell parts alot cheaper than what I've seen on ebay.  The hydraulics on the front and rear could be used for some other project if you needed it.  I am in Fyffe, AL 35971, near Fort Payne, AL (Northeast AL) and I can ship anything that UPS will accept, at actual shipping charges.  If you're interested please let me know, I'm having financial problems at the moment.  Thanks alot, Nathen.
