I've owned an LM2000 (56v 20") for 3 years. The spec's for this mower say this motor is 800 watts. Google translates this to 0.8 mechanical HP. This performs far better than a mower would with a 0.8 HP gas engine would, so the LM2000 must have a lot higher torque than an equivalent-HP gasoline engine. I remember way back decades ago when I was a teenager using a smaller 3 HP gas mowers when compared to the much more powerful 6.5 HP mowers of today. My LM2000 seems like it's close, if not at least equal to, the mowing capability of those old 3 HP mowers. I'm hoping someone might have enough information to be able to say what the rough-equivalent HP would be in a gas mower.
