3 point hitch build
1 Attachment(s)
Yesterday was a busy day in Cub Land. Was able to cut most parts out and drilled many to build 2, 3 point hitches. One for my 1711 and the other for my 782/4.
Another 15-20 holes to drill tonight. Then onto welding! Attachment 87095 |
:popcorn: Keep the pictures coming and did you make the lift bar.
|
Yes I made the lift bar. I made the hitch from my 1512. That took a lot of adjustment/ bend/ test fit. This time I just copied the bar that was working in my 1512.

Everything drilled. Started welding parts up.
Completed one side of the lift arms. Took some time to build a jig to have the correct spacing and alignment. Then welded some washers onto the side plates. Progress ended when I ran out of welding wire. Attachment 87305 |
Looking good so far, keep the pics coming!

I am running a lincolin weld-pak 100 (120 volt) wire feed welder with flux core wire.

Spent some time welding today. Top picture is with the plates tacked together.
Lower picture has plates welded together right before i welded outer arms on. The outer arms are now welded but I still have to weld inner arms on. Ran out of time. Had to load the 1512 and York rake up so I can rake out the little league inner field tonight. More time on the Cub! Attachment 87320 Attachment 87319 |
Looking good!

Hey...... before you spend a bunch of time, a flux core wire isn't going to penetrate deep enough to be able to hold the lift lever (crank arm) to that rockshaft. You will break the weld. Your welder isn't large enough. Sorry man.... it's just not going to hold. Oh, it may for a while, but it will break.
|
Thanks!
I completely agree the 120 volt welder with flux core is not the best tool for this job. With that said, I have been using the same hitch design, done using the same welder on my 1512 for a number years. It has not broken yet. Over the years using this welder I have made multiple items including a 25 ton log splitter, heavy duty trailer for my cub, repaired 1.5 ton dump trailer. Using a process of material beveling and multiple pass welding I have very few welds break. A more powerful welder is on my wish list but for now I have to make due with what I have. |
You can pick up a used Lincoln "tombstone" or "buzz-box" AC arc welder for $100, sometimes less. That would be far better than a 120v flux core machine.
I wouldn't trust a 3pt welded with flux core wire.... but it's your machine. Just out of curiosity, what exactly do you use the 3pt for? Just a York rake? |
The 220 volt welder was on hold until I had the electrical upgraded at the house. This just happened 2 years ago so first step in the right direction!
Right now I use the 3 pt hitch for: 1. York rake (4ft) 2. Small grader blade 3. Carry all. 4. Pallet forks to move empty plastic water storage tanks for maple sap. 5. Log hauler to drag firewood. 6. Trailer hitch but only once and awhile. Like my fixed hitch better. 7. Recently subsoil ripper and moldboard plow (not used much). |

But yes, as Jmech stated, the tombstones are pretty reasonable to pick up. I just got one from a guy at work for a crispy $100. Then I was lucky enough to be in the right place at the right time, a friend was cleaning out some garage space and needed a place to keep a weldpack 180 mig. I happily gave it a temporary home next to my weld bench, adding that he could come visit whenever he wanted. Keep up the good work! |

Lift link shafts almost finished. Bending the 1/2 thick flat stock is tough. What I did was make a shallow cut with the band saw. Then bent from the other side of the flat stock (i.e. hit it with big hammer). This opened the cut slightly. I then beveled the edges of cut with a grinder and filled the bevel with the welder. This seemed to allow good control of the bend location without actually having a press.

No updates on the hitch but did pick up a Lincoln tombstone for $75. Guy didn't even have outlet to show it worked. He is a friend of a friend and he agreed to give me my money back if it didn't work. Rigged up a temporary electrical outlet in the Garage to test and the unit worked fine. Will finish installing electrical early next week and back to work on the hitches!
List to do: - Weld inner arms on rock-shaft - Drill hole in hitch side for installing pin to rock-shaft - Drill holes for rear hydraulic quick connectors. - smooth all edges, clean and paint - build lift arms - build adjustable links for lift arm. |
Nice score! It should serve you well.
|
I bought a Tombstone for $50 because it "didn't work." I can email you the guide I used to clean and lube the switch contacts. Wouldn't you know I now have a welder that works perfectly.
|
All this talk about tombstone is making me hungry. :popcorn: Hows the build coming a long?

Sorry progress slowed. Spent a couple nights practicing stick welding. Was able to get one hitch welded. Then wife started me on another project.
Last year she copied a painting on plywood with exterior paint. We hung it on the side of the garage. This year she did three more. Since it was time to replace clap boards i spent the past weekend removing clap boards and putting up paintings. Now I am on new clap board duty before cub time! Attachment 87542 |

Sorry no updates. Too many other projects and multiple late nights at work.
Hopefully back onto hitches this weekend! |

Both hitches welded up. The tombstone did a pretty good job welding. Welds aren’t that pretty but they apprear strong and had good penetration.
Access hole for linkage pin drilled. Attachment 87915 Attachment 87916 |

Small steps every day!
Attachment 87977 Finished the second top link bracket. Welding getting better with tombstone. Attachment 87980 Adjuster parts before grinding and welding. Attachment 87978 Adjusters for rear lift arms. Attachment 87979 Adjusters on threaded lift arms. |
:popcorn:looking good!

Do you have a pattern for the lift rod? I have a new 1 I'd like to sell. It's from my 1864, it was used twice and then I modified the 3pt.

Few more step!
Attachment 88083 1st coat of paint. Thanks on the lift rod but I have one from my 1512 build which I used as a template. |

Well it has been a while but 1st install and test is complete!
Attachment 100709 I put the 3 pt onto the 782i rebuilt. Made a few passes on the driveway with the grader blade. All seemed good! |
Great job on the 3pt!
|
Nice work!
Great post and pictures.. I've GOT to pick up a tombstone.. This post has me banging my head that I bought a sandblast cabinet first. Thanks for the post!
|
Good job ! Thanks for the detailed photos, they will help me build my 3 point hitch :beerchug:
