With the mower still on its side grab your socket wrench and wood block. Place the block inside the blade well. This is to prevent the blades from turning while you loosen their bolts. Remove the blade mounting bolt/bolts. A typical mower will have one blade like the Craftsman 37700 I serviced for this guide (one mounting bolt). Some like my Honda HRR216VKA have two blades an upper and a lower (two mounting bolts). Each blade should have at least two cutting edges.
The 190 cc engine allows you to mow at a decent clip and it starts more easily and runs more efficiently than most side-valve engines. Also the rear-wheel drive makes it so you can mow inclines and hills effortlessly. There are more features than we have space to cover here but we would be remiss if we didnt touch on the Versamow system. This system allows you to choose how much grass is mulched and how much is bagged depending on your yards conditions. It also lets you shred leaves so you no longer need to use your leaf blower.
There is something Zen about spending an hour or two each week pushing the mower around the yard on a sunny day. The drone of the motor drowns out your thoughts as you work on a task with a clearly defined objective: Making your lawn look its best. Of course the deciding factor between an almost meditative experience and one filled with frustration is often the quality of the lawn mower you have.
