By  | 

In case you own a self-propelled lawn-mower and it suddenly stops moving automatically or becomes a push-mower and even fails to start, then you shouldn’t get worried or panic because you will just haven’t to repair it yourself using the steps I have provided below or even take your lawn-mower for service if you don’t have time to repair it yourself. However, you should always do regular/routine maintenance on your self-propelled lawn-mower inorder to prevent some mechanical-issues and to improve on the performance and life-expectancy of your lawn-mower. So, below are some of the quick tips that you can follow in order to fix any problems with your self-propelled lawn-mower and in fact these steps will work either you have a gas electric or cordless self-propelled lawn-mower.

Steps To Follow When Fixing Self-Propelled Lawn-Mower:

  1. Do a visual-inspection before starting your lawn-mower: before start you start-up a self-propelled lawn-mower always do a close visual-inspection because this will help you to solve some of the problems that may have prevented the lawn-mower from operating after powering it on. So, this process may involve cleaning-up any debris if any, tightening/replacing any loose bolts/nuts, sanding or painting any rusty structural-parts and replacing any frayed of damaged wiring-connections.


  1. Check for fuel and oil levels: before you power-on your self-propelled lawn-mower, first check if there is enough fuel/gas and even check for the oil-levels. This is very important because it a lawn-mower does not have enough fuel or oil then its most probably to stop working mid-mow.


  1. Check the speed-control cables: if your lawn-mower stops self-propelling itself or moves too slowly when propelling itself, then the problem is usually with the cables that control speed. In fact, if the drive/transmission cables become loose or break then your lawn-mower will stop self-propelling forward. so, you will need to inspect the entire cable starting from the handlebar while moving down to the transmission system and then make sure that all the cables are connected firmly at both ends. However, if the cables are damaged or worn-out then consider replacing them with new cables for best operation-results.


  1. Tighten any loose-cables on a personal pace lawn-mower: in case you own a personal-pace lawn-mower that is moving at a slower-pace, then consider checking the wire-cable that runs from the handle-bar to the transmission-system but with the engine turned-off then squeeze the personal pace-handle to check whether it moves about an inch before feeling any resistance. If this pace-handle moves more than an inch then the cable will need tightening because these cables tend to stretch with wear. So, you will need to loosen the bolt that clamps the cable onto the handle and then pull-up the cable about an inch. After tighten the bolt and then squeeze the handle once again to check whether that problem has been fixed.


  1. Troubleshoot and fix any problems with wheels and drive-wheel gears: incase the problem of your self-propelled lawn-mower is with the wheels and drive-wheel-gears, then consider cleaning or lubricating these wheels and gears as the first measure and if they still fail to work properly then consider making replacements. In fact, a self-propelled lawn-mower will move at much slower rate incase the drive-wheels and gears are blocked by dirt or clippings so this implies that you will have to regularly clean-up these components and even spray the bearings graphite or any other type of lubrication.


  1. Check the cutting-blade: incase your self-propelled lawn-mower is vibrating a lot, makes a lot of noise, cuts poorly and even moves poorly on its own, then it may be having a bent, damaged or unbalanced cutting-blade. So, consider turning the lawn-mower off and then remove any grass-clippings and dirt under the blades then remove the cutting-blade and try balancing it by hanging it on a nail. If one-side hangs a bit lower than the other then consider filing it until it’s at the same level with other side. However, if the blade is worn-out or broken then consider buying a new blade for best results.


  1. Check-out the motor-shaft: a motor-shaft is actually a rod that connects the blade to the motor and this shaft can easily get bent if run over large-rocks or tree-stumps thus affecting the self-propelling system of the lawn-mower. So, if you notice that the motor-shaft is bent or damaged then it’s recommended to take your lawn-mower to an advanced mechanic for repair.


  1. Checkout for safety-features: most lawn-mowers are equipped with safety-features that help to protect the user while mowing. For example, some lawn-mower feature a fuel shut-off valve, a blade-control and choke and a lot more. In fact, if the fuel shut-off valve is closed or blade-control is engaged then the lawn-mower won’t be able to start-up. So, make sure that all safety-features are disengaged before starting-up your machine for best performance.


Tips To Consider When Fixing A Self-Propelled Lawn-Mower:

  • Disconnect the spark-plug cable before you begin repairing your lawn-mower. This is very important because it helps to prevent the lawn-mower from starting while under repairs which can easily lead to serious injuries.
  • Lawn-mowers spark-plugs should be replaced for at least once in year inorder to achieve optimum operating results. In fact, faulty plug will prevent your self-propelled lawn-mower form powering-on.
  • Always clean the Carburetor and Air-filter inorder to ensure proper air-flow and fuel-flow within the drive-system of the lawn-mower thus ensuring optimum performance. In fact, a dirty/clogged air-filter and carburetor can affect the engines performance and even increase on fuel-consumption.
