    That style track is not known to be a great swimmer. Interesting that it would swim a lot better backwards. If you find out why please let us know.

    Amazing rig....love the diff idea ...just wish one could split that so as to connter rotate steer.

    Amazing build.

    Do you have files for the cnc cutting?

    What is your investment in raw materials such as steel track grousers and such...not counting time or parts like wheels tyres engine trans....just basic raw materials.

    What about some limk5ing blocks on walking beams prevern body slapping?

    Have you considered going hydraulic like the mudox? Would allow much more room internally...maybe get some small planetery drives outboard driven by two hyd motors....

    Cost would go up...sadly

    Great job amazing machine.

    I will let you know if I figure it out. Looking at a Russian rig with the same track system, it looks to go 7 kph in choppy water. His tracks look fully submerged, not that it matters perhaps?

    Thank you.

    Yes I do have cnc files. There is some interest from guys around my area for a kit/plans which would be fun to do, but I didn't want release anything until I work these bugs out.

    Looking at my spreadsheet I spent:
    -$2175.16 on steel components (this includes the precut/preformed plate steel)
    -$79.05 on hardware
    -$514.37 on non-metallics (conveyor belt and polyurethane casting compound)
    So around $2800 in raw materials, not cheap. But to me the cost is justified in ruggedness and adaptability. This year though multiply the steel cost by 1.4, because tariffs .

    On my next machine I want to move to independent wheel suspension with torsion bars, I have been looking at Ford and chevy truck torsion bars for a foundation.

    I withdrew from hydraulics because of cost and complexity like you mentioned. Not too mention my history with hydraulics is a little tainted from previous projects (don't ask lol). In the end I was going for that 'good enough' design, where it uses simple/common automotive mechanical components.

    Did you just bolt that extension onto the existing track? Are you noticing a big difference in flotation in the mud?
    Looking good.

    It still only has the summer tracks.

    I've only tested a section of the extension back in early April. Extensions will only be for winter use to keep up with the Tuckers and Sno Tracs up north, I have a feeling they will work just fine.

    Cool pictures. Thanks for sharing.
    What it lacks in ground clearance it makes up for with traction.

    Hey, I think I know. I'm guessing your drive sprocket is on one of the ends, right? Going one way, the track under the vehicle runs tense. Going the other way, the track will slacken. One or the other swims better. If you can, get a go pro , a case, and a stick and look at what the track is actually doing down there.
