WOW, I think I am starting to get Articulated 4x4 envy... That thing is sweeeet!!!

[Methos]

Ok so I got a little bored tonight so here's some more links for ya to follow. Not going to do any more searching tonight for them so so if you want more type cub cadet articulated into google and enjoy the results!

Most of the planning work is done for you.

And here we have Artie (this is the one I rembered seeing a while back)

I've been toying with the same idea of a 4x4 Cub. Guess it would be more accurate to call it a tractor with mechanical front wheel assist, but either way all four would be powered. It would look just like Dan's 100 with the Dana front end & operate the same way for the most part, but use a GM rear axle and no transfer case. Here's the math that I have thus far & what parts I would like to use. Dan's 100 is chain driven off the pinion shaft in the tranny thru a couple of gear sets then to the front pumpkin. My tractor is a 100, so I stayed with the stock tire sizes or 23" dia. in the back & 16" dia. up front. I carried all of my numbers to 4 decimal places for accuracy & ease.

Tires & Rear Axle:
23" dia. = 72.257" cir. --> @ 3 MPH = 43.8435 RPM
16" dia. = 50.265" cir. --> @ 3 MPH = 63.0259 RPM
Stock gear drive diff = 13t & 46t ---> 3.5384 : 1 ratio
Rear pinion speed = 43.8435 RPM x 3.5384 = 155.1358 RPM

Using a GM S-10 Blazer rear axle with a 3.42 ratio for the front axle would give you:
63.0259 RPM x 3.42 = 215.5485 RPM @ the pinion input

The ratio difference in the two input speeds:
215.5485/155.1358 = 1.3894 : 1

This ratio difference would leave you with a drive option (sprocket or gear) of an 18 tooth item & a 25 tooth item.

The math check shows that 18 x 1.3894 = 25.0092, but if you convert it over to a percentage of difference between the real world parts & the equation would give you: 25/25.0092 = 0.9996 --> 1 - 0.9996 = 0.0004%

A difference of four tenths of a percent is almost certainly negligible in our situations & the slop in the drive system overall is much more than that if I had to guess.

This setup would give you the addition of one gearset to drive system (the tranny countershaft to the front prop shaft) to which you could drive the front axle without the need for a transfer case like Dan's tractor has. The S-10 Blazer axle with that ratio is fairly common (up here in MN at least) because that's the gears they put in the pig when the Blazer had an auto tranny. An added benefit is that the S-10 wheel bolt pattern is the same as the bolt pattern on the rear of the 5-lug Cubs. Would like take power from the tranny like Dan did on his 100, and tweak the rest of the system a bit.

Looks like you've put a lot of thought into this. Just so you know, the bolt patterns aren't the same. The S10 is 5 on 4.75" and the Cub is 5 on 4.50".

Measure a couple of tires to be sure, but I'm willing to bet that a 23" tire isn't actually 23" in diameter. Same for the 16" tire. I think I would figure out what you'll be using for tires first, and then measure the actual diameter, which will vary by tire style, manufacturer, etc. I can find at least 3 tires here that are all the same labeled size, but are all completely different as far as actual size because they are all different brands.

5 on 4.5 is a ford pattern, mustang, ranger, most mid size fords. Just FYI!!!!!

Thanks everyone. I was looking at something else when I typed that in. Brainfart mostly. Matt G is right too... I just did perfect world numbers to see if the system I wanted was possible. It should still work with the correct tire diameters put in from that start. I was bored at work one day and this is the result.

Cub I have been working on. Used two case transmissons to power the front and back wheels. The articulation joint is a combination of two front car hubs and bearings. I have different tires to make all the tires match. Just waiting for some snow to try it out. If everything works OK this winter, I will take it apart next summer for a paint job.

Thanks for the progress pics!
