Inside the the toro self propelled mower's gear box are two main
gears, a worm
gear and driven helical gear. Every site I go to lists the worm gear,
the helical. Model is 16775,sn 9007923. Any idea why this particular
not be listed? I'll call around on Monday but hope maybe someone
and maybe where I can find one. The whole gearbox is $250 or so.
