I understand you're dealing with thick, long grass that's difficult to cut. While a power electric/corded lawnmower could be suitable, I can't make a specific recommendation without knowing important details like your lawn size and exactly how long the grass is.

For thick, long grass, you'll need a mower with sufficient power and cutting height adjustment, but the best type (corded electric, battery, or gas) depends on your specific situation.

Please use my lawnmower selection tool at the link provided below - it will help you choose the best mower for your needs by considering factors like:
- Your lawn size
- Grass length and thickness
- Power source preferences
- Budget considerations
- Storage space
