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.
After sharpening both sides of the blade place it on the kits cone-shaped balancer. If one side dips below the other continue sharpening it until the blade rests level. Return the sharpened blades to the mower and reattach. If you have a torque wrench its a good idea to use it here. Often you need to tighten the blade mounting bolt/bolts to a specific tightness level. Typically measured in pound-feet your instruction manual should list these specs. For example my personal machine the Honda HRR216VKA between 36 to 43 lb-ft of torque is required.
In the following guide we mainly focus on walk-behind mowers since the majority of lawns are served perfectly well by these machines. However if you have a lawn that is larger than half an acre you may want a riding mower. If you have a yard that is between a quarter and half an acre consider a self-propelled model. This basically means you do less pushing. Self-propelled mowers are especially helpful on hills. Also pay special attention to blade size. Look for a mower with a blade thats at least 20-inches long if you have a larger yard. Conversely if you have many narrow areas to mow a smaller deck the area within which the blade spins around is best.
