I have this mower with the 4.0 Ah battery. Is the mower supposed to start up and rev up slowly? It takes over a second. My previous electric mowers revved up in a fraction of a second (24 V). Otherwise this is a great mower. Thanks.
My understanding of the slow ramp-up to speed is, the tool is making sure there are no obstructions before applying full power.
The 12" trimmer was recently confirmed to do this in an intelligent manner, and if the guard is removed and the string is too long (operator asking it to cut a larger than designed radius) the tool will go into a limp mode.
I wouldn't be surprised if the mower is programmed to start up in a similar way for similar reasons.
