Here is a few more photos I call "barn time" that the spousal unit took a while ago. I did not bend the fuel tank in the third photo :laughing: Any questions or comments?

That barn looks cold!

I was gonna make a wisecrack about what if a snow drift blocked you in....

I guess those white wheels on the steering yoke control the individual speeds of the tracks so you can balance the speed of the tracks.

I still don't get it. how do you control the forward speed of the machine. If your foot controls engine speed and one hand on the yoke to steer and your right hand on the joystick controlling the blade.

Oh gee James, I'm not very good at describing technical items like this. Maybe we could chat on the phone? Seems you are over-thinking this... Only one dial on the column is used and its the transmission. Put it in gear 10 and you'll go fast. Or use 1 and you'll just creep forward but have lots more power. If your hands are not on the steering yoke, then the tracks go the same speed forward or rearwards. Your speed depends on the "gear" you have your dial at and whatever your engines speed is. To make the right left tracks speed different from each other, you then turn the yoke. Hows that?? Its not grossly different than the machines Kässbohrer made 15 years ago. Feel free to PM me and we'll chat on da phone.

so you do end up controlling the speed of the machine with the engine speed after selecting the appropriate "gear". It's just a lot different than the system I am used to.

Does it have actual gears, or just hydraulic flow settings? I'd assume some of that would be equivalent to how far you press the go pedal on a HST tractor. But the HST tractors do have a couple actual gears in there

Yes, but we change the dial on the fly all of the time. Its a pump volume control and you can change that and steer at the same time. You can move the dial with one finger while the rest of your hand is on the steering yoke.

No. its just a variable output pump that the dial is controlling. There is a planetary drive at the sprockets which are 2 speed. Does that count as gears???

Ya, at least if you can change the mechanical gear ratio I'd say so. An automatic tranny uses planataries & everybody considers those "gears".
