Can someone please explain how exactly the disc-o-matic works so I don't take mine apart to try to figure it out for myself?

Note: I know how to USE it, but am not quite sure how exactly it functions.

Hell, I understand DSGs, Auto trannys, SMGs, manuals, and CVTs more than I understand this.

hi everyone,

can somebody explain this disc-o-matic system ?

do you need to stop the snowblower's moment in order to switch gears ?

thanks for any info.

Zippo.  Hi, there.  Yes, you do have to stop to change gears.  Same for reverse.  Only the Honda hydrostatic trannys allow you to shift as you keep moving.  But then, they don't have power steering.  Weird.

Update:  I wasn't so clear when I posted my first comment.  I was thinking of saving unneccesry wear on the rubber portion of the one disc.  You can shift while moving, but I'd prefer avoiding that possible extra wear.  It's certainly not a mechanical problem to change forward gears, or the reverse gears, but never go from forward to reverse, or vice versa, unless you stop beforehand.

Actually you can shift on the fly. Just not from forward to reverse or vice versa or you could rupture the friction disk.

PK

in simple terms there are 2 disks one with a rubber outer surface and perpendicular to each other that contact and the farther out one moves the faster you go
