6x4 Extension Contraption
 

Absolutely sick of getting stuck in the snow I came up with this dooms day machine. Let me know what you guys think. A dumping bed will most likely be in the near future if this does prove worthy.

tracks is what it needs now.

I like it, do both rear ends drive? how does it steer? More pictures please.

I agree I like it impressive engineering at least, maybe a 5th wheel type trailor ! if the front rears high center will it spin and stop ?


128

It looks like the shifter is still on the second rear end?

That is very cool! I like it, too! :beerchug:

too bad your front drive tractor doesn't have a rear PTO...then you could somehow make a way to connect the shaft on the front of the rear transmission to connect to the PTO on the tractor's transmission. the pto spins the same as the engine, so itd be true four wheel drive with a flick of a lever.

I 2nd the idea for putting tracks on it

looks good

I like the concept. If there is not a provision for the axles to rock over terrain, then tracks would be in order. A split brake would be a good idea too.

that would be a good plowday machine. if you had ags on it or skidsteer tracks.:biggrin2::biggrin2:

Looks good! I have always thought about doing that someday, how did you do it? :bigthink:

I think you could put a yard cart box on for a dump. Looks cool.

The idea was simple enough, just like the 4x4 articulating machines seen on this site, I am simply trying to combine 2 cubs into one. Comparing tire sizes one day I had backed a trans from a 102 back up to my newly painted 122, going with the "stand back and look at it" principle for success I had created a monster idea. The most rear trans is used as a carrier bearing and weight. The power comes from chain & sprockets bolted to the wheel hubs. Looking similar to dual wheel adapters the inner sprocket is welded & spaced by a 2"x2"x6" tube, the same tube used to make attachments for my front receiver hitch. The outermost piece to the "drive spacer" is a 1/8"x6"x6" plate that has the lug pattern drilled & tapped. The frame extension is made of a C channel (8"x3") cut in half * drilled to fit the two trans-axles with even spacing for smooth operation.

Overall I enjoy the simplicity of it. The rigid frame, less the front, seems to work nicely for my chores. It handles weight nicely, I tested it & +/-800# & noticed the turning radius seemed to get large quickly on asphalt. On dirt it doesn't tear up anything more than my ags did. I have NOT been able to get it stuck yet tho. Because each side is locked & rigid I don't find the machine digging holes like the factory setup did, rather staying relatively level & not creating deep ruts. Thanks for the comments thus far, seems to be an enjoyable simple project & I will keep updating.

Wow!
Thanks for posting the pictures and your sketch. Love good sketches!

I agree, with Chris! Awesome sketches! :beerchug:

Spacing
 

I was wondering what the spacing is between the rear tires? Is the 2nd rear end in any gears when you are operating the tractor or is it that the front rear end gears drive through your chain. I think this is a very good idea. And could be a heck of a snow pusher. GREAT JOB:beer2:
