There are many different kinds of lawn mowers, each with unique characteristics and advanced mechanics. The lawn mower comprises of different parts, each important in the whole operation of mowing a lawn. Although, any service center will fix any damage or malfunction of your lawn mower, one can always try a hand at DIY lawn mower repair.

How to repair different parts of lawn mowers

Broken Pull Rope: This is a very common problem with most lawn mowers, a hard or jerked pull, or an old starter rope could lead to its snapping. To repair this problem, start by unbolting and taking the motor cover off. Once you have reached the pulley, remove the tiny screws around it in order to remove its cap. Rewind the pulley against the spring and hold it there. Once that is done, tie a knot and seal it with a flame, only if your rope has a plastic coating. Remount the pull handle on the cord to create some tension.

Starter Clutch: A starter clutch will make a really annoying noise, before starting. Remove the top cap of the engine, by unbolting the plugs. The most common reason for the starter clutch to not function is mostly a stuck pawl. A pawl is a hinged catch that is fitted into a notch of a ratchet to move a wheel forward or prevent it from moving backward. Loosen the center screw and adjust the pawl back in its place. Fit the engine cap, back on.

Damaged or Plugged Air Filter: A damaged or plugged air filter will not allow smooth start up or running of the lawn mower. If the air filter is damaged, it needs to be replaced with a motor air filter of appropriate specification. For plugged air filters, one can use soap water, to clean it. Wring off the foam and put a little motor oil on it. Wring the foam back on and reassemble.

Shaft Not Spinning: A shaft is like a revolving rod that transmits power or motion to the lawn mower. The drive is a square shaft between the engine and the differential of the lawn mower. They have two large, square blocks, that are held apart by a spring. Completely clean up all the grease, or small grass blades from there. This will allow the blocks to squeeze up together and slip the shaft drive assembly out from between the engine and differential.

Clogged or Broken Belt Drive: A clogged or broken belt drive will not allow the lawn mower to move forward or backward. It is normal for the belt drive to get plugged with the cut grass. This requires no repair, just a thorough cleaning. A broken belt drive on the other hand, will need to be replaced.

Lawn Mower Engine Repair: An engine is like the heart of any machine. It needs to be regularly maintained and serviced to function smoothly. The spark plug is generally one the reasons a engine may die down. The terminal covers should be placed tightly over the spark plugs. Cleaning and greasing them normally does the trick. If one sees white smoke billowing out, clean the air filter. If the engine has shut down due to overheating, check the connecting rod and flywheel to make sure they are tightly secured in place. Carbon buildup can also cause overheating; however, this problem can be solved with a good cleanup.

Riding Lawn Mower Repair: If the riding lawn mower has starting trouble, check for the battery. When the lawn mower does not budge from its place, check the hardened steel shafts, as they could be jammed. The steel shafts hold all four tires on. A leakage in the gas tank can be quite troublesome. If they have developed rust and have holes, they would need to be replaced.

Irregular and poor lawn mower maintenance is one of the major causes of the problems in it. Most problems can be easily repaired by DIY lawn mower repair techniques; however, if a problem is persistent, it is best to have it checked by a qualified mechanic. Now that you have understood how to repair lawn mowers, don't let that lawn stay uncut!
