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.
EGO has two 21-inch deck 56-volt lithium-ion cordless battery mowers that are quite popular and share a number of similarities: the LM2101 and the LM2102SP. The major differences between the two are that the LM2102SP is self-propelled has a larger-capacity 7.5Ah battery and it costs $100 more. For the purposes of this review we are going to focus on the features they share in common.
Other buyers comment that the mower feels and look like a toy. It seems flimsy. But they also found it could handle child-swallowing yard growth. One of the coolest features of the Toro Recycler 22-inch Personal Pace Variable Speed Gas Walk Behind Self Propelled Lawn Mower that kept coming up in our research is the blade-brake clutch. This allows you to stop the blade without stopping the motor of the mower which is helpful for moving debris out of the way.
