Start of new year project

Happy New Year everyone, they seem to come faster every year! Well the mock-up work is done, now its time to take it all apart and head to the Fab. shop. First picture shows the overall set-up. The top link hitch assemble will be 2 pieces of 5" channel welded back to back. Everything will be welded into a single fixture. The placement of the pivot pin gives me an 18" mast height (per Category 1 standards). The second and third photo are a close up of the bracket and lastly the seat in place.
This whole project started with, "What can I come up with for hydraulics" While doing some research on this I ran into the fourth and fifth pictures. Both show a model S with a hydraulic pump mounted between the governor and magneto. John Saeli identified this as the pump used on the SP-9 and SP-12 combines. More searching lead me to a gentleman who had one from his Dad's SP-12 combine. When the combine gave out he transferred the pump to his model D tractor. Eventually he passed the tractor on, but kept the pump, which lucky for me, he was willing to sell it. The last photo shows the pump, manuals I acquired and a Cross 2 spool valve which has a "float position" on one spool. I plan to use a small torpedo shaped compressor air tank as the reservoir and a Paul hydraulic fluid filter. I haven't decided if I will "hose" everything or go to the added work of hard piping.
One of my criteria was not to modify the tractor in any way. Now it can easily be returned to original condition, if desired, by a future owner. Anyway its back to my regular job tomorrow, so it may take awhile before I can get the rest done. Hope you enjoyed the project, I did, I welcome all coments.

I personally like it I think you have addressed some of the concerns that others have had on strength.

My I ask what you are planning on lifting with the 3 pT. if its a blade you will probably be ok but it its a plow I question that the 3 bolts holding the bracket will hold up over time. My concern is since the top link attaches lower than the bolts it may create a lever type pull against them and pop the head off the lower bolt.

When you lift a plow or a disk it puts a lot of strain on the top link until the implement lifts free of the dirt. That's why the top link position and strength is so critical.

Just my thoughts

Nice work so far, so please don't be discouraged by comments or questions. I have built 3, 3PT set-ups on Allis Chalmers tractors they all work and all are holding up but are ugly compared to your work.

That is some good stuff! You should have one of the few (if not the only) Eagle Hitch SC without live pto, foot clutch, and right side turning breaks. That is a neat creation in my book. I like the idea for the hydraulics too. I'm not expert on engineering by any means but I think a 2 bottom plow would be adequate for the Eagle Hitch. I would like to see that in action.

I have no doubts that the set-up would pull a 2 bottom plow as the lower links and attachments are right out of the factory. I do have a top link casting on which the holes are flipped over, two at bottom and one at top, this would withstand a pulling force better. Since I don't have a plow, or for that matter ever used one, I would have to leave that up to you to form an opinion. At present I plan on using a Danuser blade that I acquired, this should exert a pushing force on the toplink bracket. Please keep the opinions coming, I plan on going ahead with the project. As I said I am not a Farmer and have little or no experience with most common implements such as a plow or harrow. But I am always interested in something which improves on my design. Thanks for all the comments!!!

Shoot me an email if you get a little free time. Should be open below my post.

Thanks.
