Greetings all! I figured I would start with sharing some design ideas and details while I work the rest I have a couple of different push mowers I'm going to start with... I have a really nice honda that's spare.. but it's so nice.. do I really want to hack it up?? (pretty sure it has a metal deck) but I really do like is the blade clutch.. meaning the engine can run w/o the blade spinning.. kind of a nice feature. .the other is a dinosaur craftsman mower I was given that I think has some internal engine issues. (feels like a LOT of drag when pulling on the rope) I'm also tempted to use a Kawasaki FV420 engine I have because I _REALLY_ like the idea of electric start! but I'm not sure about doing the rest of what I want to do with that engine..
I plan on running 12v, Lead-acid (I'm cheap, i have them, they're easier to charge) but also, I plan to run a 12v alternator off the belt previously used for the traction drive.
i'm thinking these electric motors should do the trick nicely, (cost effective, reasonable size) i'm waiting to get more details on the sprocket shaft.. I'd rather use a 420 chain over bicyle chain.

I plan on using 13x6.50-6 turf tires, (but can also get knarly lugged tractor tires in this size too)
and these wheels:

These wheels mean they can just float on a single solid shaft... simple.
so with all that.. and the 9tooth sprocket on the motors, a 24 tooth-ish sprocket on the drive wheels and the size tire will give me the target max speed of about 4.5mph. and again, if I need hardcore torque, I can always switch to up to a 75tooth sprocket (or whatever fits inside a 13" diameter tire)
I'm thinking of using pnematic casters on the front. i plan on mowing ditches and extreme hills, so it's not likely i'll be on manicured lawns
i'm also planning on a angle sensor similar to what cell phones have to alert if the hill is too steep, or in the case a rollover actually happens, can immediately kill the engine before the spinning blade of doom becomes a problem.
i'm planning on having r/c control of the throttle, (mainly a switch between idle and mowing speed, don't really need FULL control) if I can make the electric start happen, I might just automate the choke and throttle to make it an r/c puss button start..
I plan to have R/C control of the cutting height too.. if I can find a way to adjust quick enough, I have some advanced plans for that to help avoid lawn scalping..
ok, i think that brings me to end of what I've though of so far. so now on to the crappy part.. having to spend money.. lol
I did just order a FlySky Fs-I6X which comes with the IA6B receiver, but I'm going to go ahead and upgrade to the IA10B receiver because heck it's only $20
