Cub Cadet SC500EZ 159cc Electric Start Self-Propelled Lawn Mower
There may be more expensive models out there, but none cut better than the Cub Cadet SC500EZ (21") 159cc Electric Start Self-Propelled Lawn Mower w/ Swivel Wheels. The swivel wheels make this a true zero-turn radius mower, and the 159cc motor is made by Honda. That engine is reliable as the day is long, and it will last the life of the mower. It's a 3 in 1 mower, that discharges either at the back or the side, and converts to a mulcher when need be.
The mower has six speeds so you'll easily be able to find the walking speed that's right for you. It has a keyed electric start with on-board battery, so you won't be using a pull rope, height is readily adjustable on all 4 wheels, and it even has a high pressure deck washing system. Although not an inexpensive mower, it’s one of the better values available on the self propelled market with a three year warranty and Cub Cadet quality.
