I'm sure there are more than one answer. I know for a fact that some have gearboxes with multiple speeds and reverse. And zero-turns are probably using either hydrostatic or a gas-electric direct drive type system.
But is there another option? I made a post in a go kart forum about how it would be really cool and useful if someone made a kit to make the comet torque converter ( a belt drive CVT ) from an automatic shifting thing, that just shifts based on RPM and centripetal force, to one that was shifted manually by a lever.
Anyway this one guy said thats how his riding mower worked. I'd never heard of that before but when I thought about it, it makes perfect sense. Since you want your blades to spin at the same optimal speed but you want your driving speed to change. Doing that with a belt drive cvt that you can manually control sounds like a very easy way to do that.
So is this a thing in riding mowers?
Is it a common thing in riding mowers?
If it is a thing, how exactly does the mechanism work? I tried looking up the parts breakdown of this guy's mower to see how it worked but there wasn't nearly enough detail for the function to make sense.
For the go kart version, I was thinking of a sequential shifter that would work similar to the way a mountain bike trigger shifter worked. Each forward or back shift would pull or release the shift cable in a linear fashion, and that would move the belt as the drive pulley was squeezed by the shift cable. A setup like that would need a preset number of gears to function, but those "gears" would basically just be detents in the shifter, they wouldn't actually exist in the belt drive. So lets say you had 7 positions. Fully released would be neutral, the belt wouldn't grab. Then as you shift up from lets say 1st to 6th, it would squeeze the drive pulley more and more, shifting to higher and higher gears. This would be an awesome solution for a go kart. It would add a fun factor for screwing around, and being able to keep it in low gear at high RPMs would let you use it more as a utility vehicle too, which would also be very nice.
