Oh, if reverse engineering were not just that cumbersome :-\ would really be nice to test this on a brake motor test station.

But still nobody out there who knows what this figure means exactly?

Still worrying about battery temperature. Ordered power resistors in China for some package scale tests, but looks like they got stuck in Christmas parcel flood :oops: So I built a small test pack (4S1P) that fits my discharger at hand and pack it into some insulation to get a rough idea. I...

Thanks for the image :) Looks like an elegant, lightweight solution. You have good lathe including operator in your team :thumb: ? Have you tried smaller front sprockets? Could make live much easier. Why do you still use the genuine 14T there.

Thats not my business. Full stop.

....well, yes, and a lot less material to buy in the beginning. :wink: But also a lot less money to make for the manufacturers and dealers, of course. May that be the reason why their prototypes still stick to the dino paradigm? :oops: Another motivation is that I like the way of living as...

When robo lawn mowers and robo vacuum cleaner entered the market, I kept laughing for quite some time. But in the mean, they are an established concept. Isn't this right the same idea of downsizing, combined with autonomous operation?

Interesting Image. I like the crane they use to handle the cable - looks like a standard piece of equipment, no need to reinvent the wheel. I also like the reeler. Hope they did not reinvent this one. A bit large for my taste, but I'd like to get such a thing. Where may I look? Crane...

Yes, that's the reason why I'd slow down for additional energy efficiency. I'm not sure where the optimum is, but I remember that somewhere above 4 km/h, power requirement increases at disproportional high rates, producing additional wear and soil compression. My plugh ran at 250 HP before, at...

:bigthumb: In the Votol-Thread, you mention a 2-stage transmission. How did you make that? Do you think that this high ratio is required? obviously, if you even want to use a larger rear sprocket? I'm going to convert an old KL 250, using a QS 138 with Votol 150, and I'd like to try it single...

regarding the question of till vs no till: That's not the point for me here. If can drive an electric gadget in parallel tracks over the field, I can let do it pretty much anything I want. So I'd like to leave evergoing agricultural discussions where they belong - they have their place there, no...

My Idea was to use ordinary standard industrial asynchronous AC induction motors. They are designed for 24/7 and quite cheap. Simplest design would be to attach each wheel to a simple worm gear motor. Had the advantage that I don't have to design for a brake. But worm gear may not be the best...

Yes, of course, you can use Glyhosate aka Roundup, of course. But I'm in organic farming, so well, let's say - I don't like that - OK :wink: I've been watching no plugh systems in organic farming coming and going for decades. Maybe in some areas it may work - in my area I don't know anybody...

still playing with the cable loss calculator. Losses scale inverse to the square of voltage, and DC is more effective than whatever fluctuating stuff such as AC. I think I should go for DC at max of the cabling rate. If I stay with H07RN-F - which is a standard cable type, produced at high...
