How to Repair Different Parts of a Lawn Mower
To repair this problem, first unbolt and take the motor cover off. Once you have reached the pulley, remove the tiny screws around it and remove its cap. Rewind the pulley against the spring and hold it there. Once 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.
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.
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.
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 a 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; 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!
