Parts of a Lawnmower Lawnmowers are usually composed of several parts, each with a particular job in making the entire machine work. This makes mowers simple and complex at the same time. Simple because being familiar with each of them makes replacing each part easy as long as one knows what needs to be changed. They are also complex because it takes a competent mechanic to know where a particular part goes and to service the machine. Don't worry though, because if you're just an ordinary lawnmower owner, we've listed for you some of the basic parts of a lawnmower. 1. Blade - this is where metal meets the grass. The blade is responsible for cutting the grass and doing it neatly and evenly. Depending on the mower, it can be made of materials such as steel, aluminium and plastics. 2. Engine - if you own a motorized lawnmower, this is what keeps your blades turning. Engines used in lawnmowers are typically the single stroke types which pack enough punch for the job. 3. Handle - this is the part of the mower where you have the most control, for the human-powered ones at least. When buying this part, make sure to get that which is made of sturdy parts like stainless steel or any lighter alloy and fitted with rubber to prevent your hands from slipping. 4. Wheels - help in moving the lawnmower, especially for large ones. They can be made of different materials depending on the type and size of lawnmowers. For example, small, push-type lawnmowers are usually equipped only with plastic wheels while larger ones like the ride-on types have steel wheels.
