Some lawn mowers such as the Craftsman 37705 have a washout feature. It is essentially a garden hose fitting on top of the circular blade cover. This allows you to pump water into the blade assembly while running the engine. That action is designed to flush dirt and grass debris right out.
Several buyers suggest coming up with a mowing pattern that moves away from the outlet and thus makes it harder for you to trip over the cord. One buyer found that the motor would get dirty during use and recommended opening it up and cleaning it with compressed air. When you first lay eyes on the Sun Joe MJ401E Mow Joe 14-inch 12 Amp Electric Lawn Mower you may be struck by how small it is. At 29 pounds it weighs almost half as much as the next lightest mower on our list. This makes it easy to maneuver but it does raise questions of durability.
The EGO LM2101 is the highest-rated electric-battery mower on Consumer Reports by far. Its lowest category rating is for its bagging for which it is rated “good.” Despite testing the push option the reviewer found this mower was easy to operate and had effortless handling. However they found the 40-minute battery runtime to be fairly short a common issue with cordless electric mowers. Techaeris tested the EGO LM2102SP and found the battery lasted 60 minutes which was long enough to finish the reviewers 1/3-acre lawn. He estimated that the yearly cost to operate the EGO would be $1.50.
