My LM2100 has the 5 Ahr battery. It has an adequate amount of capacity to cut my 1/5 acre Mid-Atlantic lawn. The grass is not drawn upright by the air circulation within the mower deck if it is configured for mulching, which results in the cut looking uneven no matter if the blade is sharp. If there are leaves present while cutting the grass, the mower does not pull them up and throw them into the attached catcher. That's disappointing. Please improve the blade design to draw more air for even cutting and collecting any leaves present while the mower is cutting the lawn. Thank you.
