Just a bigger lawn mower, upping the ante a bit.  Also, I would really like for it to have a turbo button on the handle so I can run it at full power whenever I want instead of just when it hits dense stuff.

22" & 30" but it has to be able to MULCH well or they would be missing the boat again. The self propelled function would have to be more robust as well. That's the only other feature that has failed on our two 21" SPs. We returned one mower that would only go in low speed permanently and once in a while the others will temporarily lose the variable speed function while operating in rainy conditions.

A user selectable blade motor "throttle" would be nice, and the default setting as it is right now (auto speed adjust) could be called "Eco Mode" or something like that.

How about a countdown timer that estimates remaining run time based on current battery level and cutting power? Kinda like the "miles remaining" on a car's fuel computer? This way you could tailor the speed of the mower to the size of the job if battery capacity isn't a problem.

This will be a 54" mower. The hard part so far has been getting the geometry correct so they all 3 articulate in 2 axis. Along with following the exact same path over hills so the connection point will be critical. They need to pivot in the Pitch (up and down) and roll axiis, Not Yaw (left right) So to do this I do have the design finalized. It's a 2 axis pivot thingy I have to fabricate. I will need 8 swivel caster wheels for this to work. Zero turn is going to be kind of important I think.

I have the motors, and controllers for the reels. I will try to push these as they aren't terribly heavy. Maybe 100 lbs all together. But I think I'm going to have to propel them. Then I might as well make it remote control with a virtual reality camera lol. But it's coming along.

Hoorah for Diablo Sawblades.  You're not going to push those through thick grass, and as far as goes towing it behind a tractor, wait for a piece of debris to jam it up.  If you can solve those two problems, it should work well.

Oh yeah, and Blue, that would be way more disgusting if it weren't clearly brown paint.

The reels will be powered. Shouldn't care about thick grass. As long as the caster wheels aren't too small. I think 8" should be fine. But I think I will need to self propel it

reels vs rotary?  ah, atomtwister is correct: debris coming into a reel is a problem.

Reels all day. Debris is easy to keep out, just pick it up. Since I'll save like 6 hours per week mowing, I'll just pick up the sticks. Or build some sweet contraption to pick em up for me :)
