So, i'm having a thought, and I'd like input for good or ill. Ok here's my logic. I'm considering a skid-steer from a peerless four speed rearend from a craftsman. Basically I take the last three feet from a craftsman riding tractor frame, a vertical shaft gas engine from an old pressure washer mounted ahead,  Basically what is in the picture attached. My question and query to all you really experienced guys. Is "What am I missing?" "Why won't this work?"  My thought for the steering actuation. What i propose are basically plywood discs mounted on the inside of each wheel, with a curved steel band, that is attached to a lever, which when pressure applied slows the left so the right side turns and vice versa.Given the limited slip design of the rearend, it seems almost too perfect... 

A free-wheeling front-end, with 31. 10.50's truck tires side-wall cut out. tire inflation to act as extenders..... critiques are welcomed.  Ideas are highly encouraged. Thanks!!

You will most likely break that lawn mower differential with independant brakes.

   And when you get to the working stage, what about leaves, sticks, mud etc. getting inside the tracks. You know you wont just run it on cut grass. If the tranny is truly limited slip that will present steering problems itself.

Similar rigs have been built. My issue would be the ply wood disks and band brakes. Depending on which differential you have. It may take some serious brakes to turn it. It would help to know which transaxle you have.

 

And you will have to keep the chassis/engine level.

Absolutely!

Go for it. Great way to spend some shop time, have a few pints and some

fun.

 

You could cut some holes in the tracks, to eject any dirt. But, you may just

pick up more that way.

Slot the frames to slide them to help tension the tracks. Of course, then you'll

need a drive belt tension system.

Worst case scenario is it will not work. I think it was Thomas Edison who said" I have not failed. I have found 1000 ways not to make a light bulb.

Would you expand on keeping the engine level? And as for brakes i have two discs and calipers from 2 mini quads. Bought a forney stick welder for a whoppin $40 so modifications arent an issue. The peerless rearend is the one in my gallery pics. It was a salvage i unmucked, so its a freebie and if i break an axle, i bet itd make an awesome winch.... Also going to 2" holesaw drill the tracks for debris release. Keep it coming guys. Thanks!!!

utube , mudders from ride on's & such , there was a lot of that stuff to watch a ways back .same thing you are trying to do , btw disc brakes & calipers off cheap import motor bikes do a wonderful job too hydrolic type , not cable 70cc up type & easy to set up as well

The engine needs to be kept relatively level for proper lubrication and proper carb operation..

I have two identical peerless rearends.  which if faced towards each other, and the one facing backwards stays in neutral. Could culminate into a skid steer that will have four speeds in either direction..... Thoughts gentlemen??

I like you really want a small skid steer. Over the past 5 yrs have researched and schemed fur unmeasurable hours.
Like others have said I have my doubts about a gt transmition being strong enough for the job.
If you do some digging back in the Popular Mecahnics arching a tractor tire there were plans to adapt an automotive differential and tractor tire for tracks.
If you google Mini Skid Steer you will find many ideas, and there are plans out there and even kits available.

Easier still might be finding a small skid steer and rebuilding it. Bobcat made models 310 and 317 that used clutches for steering and can sometimes be found for scrap prices. A guy who lives around the corner from my dad has a little guy (brand unknown) he has repowered and it is ones lick little loader. Lauman Little dippers are rare, Rounders, Ericson and many other brands show up once in a while. There is a thread on the net where a guy found a bobcat 317 0r 314 in a farm junk pile, restored and repowered it and had less than a grand in it.

Need to correct myself, I transposed some numbers. There is in fact a Bobcat 317 but it is a mini-excavator.
The model skid-loader i was thinking of is a 371

I know this is an old thread...but have you given any thought to a borg warner T20 transmission? Their stout as hell and were used in amphibious 6x6s.
