Lex Berezhny 6:14 PM Marcin: Does the length matter? Maybe if the platform is longer the powercube could be placed directly on platform without interfering with tracks? I assume the width is importan to fit through standard openings? But length could be longer, right? It's that dang Universal Rotor, it's just so huge for a "micro" tractor :-D me 6:16 PM To within practical limits of maneuverability. The longer they are, the more radial stress on axles upon turning. Our general design principle is not longer than wide. Toro is 70". http://www.toro.com/professional/sws/brochure/Track_specs.pdf Remember that we are using gutterpunk bearing systems - common 4-bolt flange bearings not designed for axial thrust. Lex Berezhny 6:16 PM okay, i'll keep that in mind, i'll try to modify the sketch, unfortunately i accidentally deleted the one i did yesterday, but that's okay, i'll try to make a new, better, one me 6:17 PM Otherwise, price goes way up. That's why we are doing articulated design - to allow huge machines with minimal axial thrust. sorry, radial thrust. Lex Berezhny 6:17 PM And there is no way to reduce the size of the rotor, right? me 6:17 PM Articulation for larger machines. No. Lex Berezhny 6:18 PM okay I'll think about it and try to come up with a new design and post it, I'll make sure to upload the sketch to wharehouse this time me 6:18 PM Basically, the above allows 10-100 cost reduction over industry standard Cat D7 bulldozer. Uplaod the old one too. Lex Berezhny 6:19 PM I accidentally deleted it. If i can't come up with a new/better design I'll recreate the one I did yesterday and upload that. me 6:19 PM https://www.facebook.com/OpenSourceEcology/photos/a.10151381815921562.574965.66469461561/10154027343551562/?type=1&theater Lex Berezhny 6:20 PM cool
