Two transmissions in line?
I am building sort of a cheap version of a skidder/forwarder and I'm thinking of putting two NM435's in line. Has anyone done this? I would be interested in any tips/cautions. Thanks

Never thought of that, it woudl seem like it would work. Seems like it would work well with rock crawling rigs or similar. But i see it as having Overdrive a 1:1 ratio and everything else increasingly smaller.
Quad why would you do this on a swamp buggy, dont you want wheel speed, or is it to get those HUGE tires to turn in the first place?

The more I think about it, the more I am leaning toward two transfer cases instead of two transmissions. I think the input shaft on the second transmission might not be able to take the torque of the the first tranny in granny-low. If I use divorced transfers it should be real easy to put two in-line behind the tranny (just cut-to-length shafts and mount them, I just have to get the front shaft from the last transfer past the first transfer ... I think I can just mount it tilted to one side ...) and I think they would better handle the torque ... right or no ?
I heard about a guy who put a standard in front of an auto; That might be better strength-wise. I think he removed the torque converter completely ...? I don't know alot about slush boxes.
What do you guys think?

quadzjr, nice work!
Thanks for the input guys.
A little OT, but has anyone put a t.case in backwards for a fifth gear effect?
I've also got a 2wd f350 with an NP435 and if I put a divorced t.case in line backwards, I might get better mpg if I put it in low range, no? With a t.case with a 2:1 normal low range wouldn't that be like a 0.5:1 high range if I put it in backwards?
Thanks

Why not use a 2-speed rearend? I believe there are some good ones on f600's ... Also mid-70's Internationals, and the 1972 to 1977 Dodge Medium Duty Truck (D-400, 500, 600, 700, 800) ... Then there is the '40 Woody Wagon ...
