OutdoorEnvy 1,522 #1 Posted January 24, 2023 So I've been wanting a 2 inch rear hitch receiver for the tractors and came across a hitch receiver off a 97 F-150 that looked like a perfect modification project for this end. It is straight square tubing and nice long mounting brackets. Got it cheap enough and decided I'd have a go at making it fit. The 312-8 will be the fitment rig. It'll also get used by the C-100. after some measuring it was time to cut it down to size and remove the clevis hitch all work was done with an angle grinder and drill. But this wasn't too complicated a project. So I trimmed down mounting brackets and used that to replace the top mount bracket from my plow mount. Measured all holes out and then drilled holes for the receiver part to fit. It's not the most precise cutting as this was free hand but it'll do the job. I'm going to weld in some some coupons on the square tube ends to close it up and paint it all regal red. But for now I'm pleased with it and it's perfectly functional. Just in time for possible snow too! So this now has the 2" front and rear receivers. Should make it easier to add some weight down the road as well. I'll do an update when it's painted. thanks for looking! 7 11 Share this post Link to post Share on other sites

I’m sure it’s an auto correct flub, but I’m stumped! 2 Share this post Link to post Share on other sites

They're little square or rectangle pieces of metal for welding. Usually what people practice with or use to make tabs or gussets, etc. 3 Share this post Link to post Share on other sites

The word "coupons" is usually used to define a sample for testing, I think he is referring to gussets. 1 Share this post Link to post Share on other sites

Well the guy who showed me a little about welding called them that...so you know how that goes...maybe it's a regional slang?

ebinmaine 67,899 #7 Posted January 24, 2023 Excellent work there. I'd like to add something on the fitment here having done this myself in the past. I've built one hitch and modified another and they were both for eight speeds. When I went to install it on the 1975 Automatic last year it did NOT fit. Automatics are a little wider than the manuals. I've kept a bad Automatic casing set aside with my old three speed. Both had bad outer bearings and were shredded. They will be used as a jig to be able to use to make my future hitches. 2 1 Share this post Link to post Share on other sites
OutdoorEnvy 1,522 #8 Posted January 24, 2023 @ebinmaine Thanks Eric. That's good to know. Both my rigs are 8 speeds so should in the clear on this one. But my friend has a 417-A that I probably would've assumed matched as I may make up one for him if I find another hitch receiver. 1 Share this post Link to post Share on other sites

If you get to that point just let me know and I'll snap some pics and measurements on the core transmission I have. You can find those receivers by themselves on the interwebs for less than 20 bucks. After that, cross pieces and braces depends on what you have laying around. 2 Share this post Link to post Share on other sites

moe1965 743 #11 Posted January 24, 2023 I did the same setup on one of my tractors but I mounted the receiver upside-down to give me a little more height for moving a small landscaping trailer around and still have the smaller hitch that came on the tractor to move my small yard trailer and lawn roller. 3 Share this post Link to post Share on other sites

We did that on Trina's Military Tribute Tractor, 856, "Millie". Originally I did it so she could use the Single Ripper Spike but I came home one day to find the Monster Splitter in a different place. 1 Share this post Link to post Share on other sites
Lee1977 6,698 #13 Posted January 25, 2023 Two receiver hitches is better then one. The top one is braced to the top of the transmission. The bottom one hooks on to the top one and is held in place by the WH hitch pin it's easily remove. 7 Share this post Link to post Share on other sites

The 8 speed 10 1/2" will clear the cast triangle reinforcements. If you have snow blade bracket on the tractor you need to make the mounting holes match up. 1 Share this post Link to post Share on other sites
OutdoorEnvy 1,522 #15 Posted February 6, 2023 Well got the ends welded up and painted it Regal Red! First time filling gaps welding and it was a learning curve. So don't expect to see a pretty bead on them. But they'll do the job. Looks much better than rusty black! Thanks for looking! 4 4 1 Share this post Link to post Share on other sites
Tonytoro416 1,035 #16 Posted February 7, 2023 Looks like it will hold up just fine. I have learned when welding and doing fab work FIT UP is everything. I learned to spend more time getting things to fit really nice rather than trying to fill gaps with weld. I am definitely still learning. Also weld coupons are a thing. Can be found on the internet. As someone said generally they are precut piece intended for welding tests and certifications. Good job man looks pretty good 1 1 1 Share this post Link to post Share on other sites

Both the C Automatic and Gear drive tractors use the same attach-a-matic. Am I correct that your saying the main "gear housing of the automatic is wider so you have to account for that in how your side angles are mounted. If that the case, the a rear receiver hitch designed to fit on an automatic and use the attach-a-matic undir it, would also fit on a gear drive - Correct? 2 Share this post Link to post Share on other sites

That's the key there. A home made hitch I built to fit 3,4 and 6,8 speed transmissions didn't fit my Automatic. But... A hitch built on an Automatic should transpose to a manual transmission just fine. The Automatic transmission has a larger square size to the axle tubes. 1 1 Share this post Link to post Share on other sites
ranger 1,758 #19 Posted July 22, 2023 Nice job👍 Is it connected to the drawbar pin lugs? If not I think it would benefit from a couple of lugs underneath the cross piece to brace the receiver to the transmission. Because you have the four mounting bolts in line with each other, and at right angles to the receiver tube, any heavy weights hanging on the hitch further out will try to bend the mounting bolts. More so over rough ground. Bracing to the trans will help prevent that. Due to the cutouts in the vertical legs of the angles the receiver is bolted to, you have lost some stiffness here, and these could bend. Again bracing to the drawbar pin mounting on the trans would help. These comments are certainly not meant to be a criticism, just wouldn’t want to see something potentially bad happen that could be avoided. 2 Share this post Link to post Share on other sites

Debating designs as the draw pin in my C-100 is seized. So thinking of a C shape to fit over the top and sides on each end to help with down pressure mostly. I'll post an update with what I come up with. 1 Share this post Link to post Share on other sites
