Forgot to mention I also have fully functioning brakes, an important bit. It is much faster than the chain drive but can still run it full bore at maybe 10 m.p.h. Enough for a mower, I suppose. Also this didn’t seem to put any strain on the motor, which stayed cool. Also noticed my older battery is going bad and neither is fully charged. So maybe it would be a little bit faster. I’m starting to lust after those pricey lithium batteries. Much quieter than the old mower but the transaxle probably needs some grease, after 20 years of mowing in the Texas summer.
