Should I switch back to gas for thicker grass?

I’d check the basics before replacing it. A blade can be sharp and still be the wrong shape for the cut you want, and a tired or damaged blade won’t help. Try mowing when the grass is dry, raising the deck, and taking less off per pass. If it still leaves a poor finish or bogs down, the mower may simply not suit your lawn.

If it’s regularly thick grass you’re cutting, gas is a reasonable choice. It can be more forgiving when the lawn gets long, and a local repair shop can be a real advantage. Just factor in the extra upkeep, fuel, noise, and storage. Experiences with particular mower models vary, so I’d compare the cut and service options rather than assuming any gas mower will be an upgrade.

I wouldn’t write off electric without checking the exact model and battery setup. Runtime and cut quality differ a lot, and some newer designs handle tougher grass better than others. A spare battery can help with coverage, though it won’t fix a mower that lacks the cutting performance you need. If you like the quiet and lower-maintenance part, it may be worth trying a better-suited electric model before switching.
