As for the height of the handle, that will vary depending on a few factors (handle position, deck height, the position of the user's hands, etc.), but an approximate range would be between about 35"-42".  If you need further support, then feel free to ask another question.

A:  No. I only put one battery in at a time. I tried to use both batteries the first time out, but had trouble lifting the batteries out, as I didn't have the strength to pull from the top, and very little room to get my fingers between the batteries.

A:  Hello, Batteries - This lawnmower has dual active battery ports, but only uses one battery at a time. To switch from one battery to the other, simply remove the start key and rotate it 180 degrees. When you reinsert the key, make sure that the arrow on the key points to the battery in use.
