CAD files for a removable three-point hitch

[jesusgatos]

Just uploaded some CAD files to theCAD Library for a removable three-point receiver-hitch mount for a deuce and a half. Started designing this a while ago, after seeing some of the receiver hitches that other member had posted pictures of on here. Decided to build a different type of hitch for mah deuce but thought somebody might find these files useful. Dimensions are unverified and the design is unfinished. If anybody uses these files, please let us know how they work out.

These mounting brackets are intended to be bolted to the frame using the three existing holes in the bottom of the framerails where the rear-most crossmember is riveted to the frame (rivets would need to be removed and replaced with bolts). The side-plates are intended to be bolted to the frame using two existing holes where the grab-handles are located, and three additional holes would need to be drilled to help distribute the load.

Was planning on using these mounting brackets to attach two triangulated tubes that would have been attached to a receiver hitch that would have mounted to the pintle hitch like this. The whole receiver hitch assembly could be made to be removable, but I was planning making it a semi-permanent installation. Had an idea that would have allowed the vertical pintle / receiver hitch part to be folded-up flat (horizontal) so that it would be out of the way when not in use.

In the end, I decided that I'm just going to make a high-clearance receiver hitch that will be permanently mounted to the rear crossmember. Will allow me to make better use of the space behind the rear axle (between the framerails) for storage and a drop-hitch is a relatively small item to store somewhere on the vehicle. Will most likely add a few different mounts somewhere so I can store multiple receiver hitch accessories, sort of like what I've done on my Tacoma.

This design isn't finished either, but I don't think the basic design requires much of an explanation? Here's a pic.

anyway to convert these files to a pdf so we can view them?

 

[jesusgatos]

Sure, I can post a PDF but if you download the EPRT file and then download/install eDrawings you'll be able to view the 3D CAD model. eDrawings is a free CAD viewer made by Solidworks, which is the CAD software that I use to design all this kind of stuff.

I got a question ?On the reciever mount what are you planning on using to space it out on the back side of the crossmember?And is it just gonna sit over the stud of the pintle hitch or are you gonna put another nut on the and allow it to spin like it does from the factory?

Reason I asked about the PDF I want to down load it to my Dell Tablet so I can show it to my freind.

OK, here you go. But I haven't created any dimensioned drawings, so I don't see how this would be any more useful than the screen captures I already posted.

If you do , do you plan on sharing them?

 

[jesusgatos]

Sorry no, I probably won't make drawings for many of the files I post. It's just kind of tedious and time-consuming, and I don't have any personal use for them. Maybe someone else will create drawings to share?

One of my next couple of projects for my 'Mog is going to be a 3 point hitch so I can use some of my John Deere's attachments on it. Just be handy now and them. They have factory 3 point hitch set ups but the mounts on the axle, I've been told, can be busted if they take a decent hit. Anyway for the CASE deck trucks there was a pin on 3 point hitch that was pretty neat. What I'm looking at doing is similar to the CASE deck pin on unit and will pin on to my rear winch shackle mounts and two other places. Here's what it's looking like so far that this is prolly very close to the final design with the exception of adding a little more steel and some other final touches. There will be two links that pin into the lower rear of this unit and then run back up to the frame. I have the heavy duty frame on my truck so there's not much worry of overtaxing anything with frame loads.

Sorry, missed this post. Are you talking about the hitch I posted a screen-capture of in post 3? If so, then I'm planning on welding that directly to the crossmember and effectively boxing-in that portion of the crossmember. The vertical bracket on the backside of the crossmember would extend to meet the triangulating braces, and would be welded to those, and further gusseted/reinforced. The three holes in the vertical bracket on the backside of the crossmember are sized to allow the swiveling pintle to be removed/installed (holes are size to accommodate nuts + sockets). Does that answer your questions?

Gotta admit, I'm not quite sure what I'm looking at. Could you post some pics of something like that installed on a truck? Just not too familiar with that type of heavy equipment and want to understand what you're talking about. Thanks in advance.

Yes thats the one i was talking about .I was thinking it was gonna be a bolt on..But it all makes sense being a weld on unit ....I like the idea of that one

Jesusgatos, here's an example of the Case Deck pin on models. Sorry the pics are crappy...for some reason the attachment thing was telling me my good pics were .bmp's. ??

 

[jesusgatos]

Thanks, but I was asking a more fundamental question: What does that piece of equipment actually do? Looks like it would raise/lower accessories that could be mounted to a vehicle? Like a snowplow?

 

[spicergear]

It's a 3 point hitch like a farm tractor...so anything that can pin on to a tractor (basically...there are different sizes of 3pt hitches) will fit. I'm going with class 1 so it's the same as my John Deere. I can hook a wood carrier, log splitter, 'T' bar hitch, my forklift back plate, blade, etc. And if I built a PTO centralizer I could run my baler, hay rake, sickle bar, or brush hog. The upper single center link is not shown, but the mounting point is in the first picture.

Hope that's a more fundamentally correct answer.

that would be cool having a removeable 3 point hitch on a deuce. It may be impractical, but still cool.I thought it would be neat to have a plow in the front and a 3 point snowblower in the back... that would make snow piles disappear! have to have an engine on the blower to power it seeing the deuce does not have a live PTO.

I wonder how many bottom plows a deuce could pull... wouldnt that be neat to see!

Mogs make up for this with gearing. The 20 speed transmission for example is basically the six speed with the cascade box with the extra low ranges in front of it. They are meant for PTO speed matching where you need PTO rpm and slow, slow wheel speed like snow blowing as a good example.
