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.

Hi Keith.  This is completely normal and by design.  A slow startup doesn't require the spike in amperage to get the mower up to speed and is easier on the batteries.  It takes mine about 2 seconds or so.

Ditto. And great explanation.

Still much faster than checking the oil, fueling up, yanking a cord, and waiting for the engine to warm up though!

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.

Whenever I shut the mower down while it is on the lawn, I always tilt it up on the rear wheels when restarting to allow it to get up to full speed before resumption of mowing.

Absolutely, Tim. Too much drag during start up (blades moving through grass) would surely upset the mower.
