The riding lawn mower can save hours of work and allow lawn maintenance to be carried out in a relatively short time. These are valuable machines and regular maintenance is necessary. When there is a problem, it may be possible to carry out an equipment troubleshooting without taking the machine to the a shop.
Lawn Mower Repair Troubleshooting Tips
Here are seven useful tips on equipment maintenance. These should only be followed by people who are familiar with riding lawn mower repair and are sure they know what they are doing. If in doubt, advice on its troubleshooting should be obtained from the shop.
- The first problem that may arise is that the riding mower engine does not crank. There may be a simple reason for this, for example that some safety controls are not functioning and the mower will not start until these are operating. Check that the parking brake is correctly set, that the mowing deck is not engaged and that the operator of the mower is correctly seated. It is also worth checking the battery to see if a cable has been loosened by the motion of the machine or is not connected properly. The fluid level in the battery could also be checked, but if in doubt leave this to an expert. When checking the battery it is important to avoid spilling the electrolyte. This is diluted sulfuric acid and can burn the skin as well as damaging clothes.
- If the small gas engine cranks but does not start, the fuel level may be too low. If there is enough fuel, the fuel line could have become obstructed. In this case the fuel line should be cleaned and the fuel filter replaced. The throttle or the choke should be adjusted correctly and you should consult the manual to see the correct positioning of the choke for the model of your equipment. The problem could also be caused by a problem with the spark plugs in lawnmower engines. A spark plug tester could be used to test the plugs and find any faults. The plugs should be cleaned regularly.
- If lawnmower engines are smoking this may be a result of too much oil, so any excess oil should be removed. If the problem persists it may be worth checking the crankcase vacuum. Loss of vacuum could be caused by defective lawn mower parts such as a broken or defective dipstick or dipstick tube, or there could be internal damage in the small gas engine. This problem could be fixed by replacing the faulty parts.
- Excessive vibration of the equipment could be caused by damaged mower blades and may be solved by replacing these or lawnmower parts such as pulleys or spindles. Lawnmower parts can be damaged during lawn maintenance if the ground is uneven and there is a bumping motion. The problem may also arise if the belt is twisted or torn and this should be replaced. Vibration could also result from loose mounting bolts or if the cutting deck is in the wrong position.
- If it is not bagging or mulching properly this could be due to the engine speed, as these functions only operate smoothly at full throttle. The mower blades will cut properly if the deck is set up properly so that it is slightly lower in the front than the back and is level from one side to the other. If the grass has grown tall, the deck should be at a higher setting for the first mow. The blades themselves should be cleaned and sharpened regularly. Where there are problems with the lawn maintenance this could be because the grass is too wet and cannot be cut easily. The problems will be solved by simply delaying the lawn maintenance until the grass has dried out.
- If it does not cut the grass when going in reverse you may find that this is a safety device built into the riding mower engine. The cutting deck would then need to be disengaged first before the mechanism will allow the mower to be put into reverse. The manual should be consulted because more recent models could have the capability for reverse mowing.
- Another situation that could arise is that the mower does not move freely in neutral. This may result from incorrect positioning of the transmission relief valve. It is also worth checking the brake which may not be completely releasing and is therefore not allowing the mower to move freely.
