I don't often run it for a long time, but when I get the chance I don't want to have to cut my work time short or spend an extra $300 to cut down trees and not have to worry about the running time.
There is also a company that offers a stand on mower comparable to what I use at home, but it would be about $18k to replace my $4k mower with an electric option.
I am interested in the responsible, environmentally friendly, option, but it is hard to swallow.
