Buying any kind of equipment is a kind of lottery, but a lot also depends on the gardener. In caring hands, and Chinese samples serve for a long time and do not fail their masters at the wrong time. And if you forget on time grease gear lawn mowers, do not clean filters, use cheap low-quality gasoline, then garden equipment from the most famous brands will become a headache.
Gear Lubrication lawn mowers one of the most important elements of maintenance of a gas trimmer, which should be carried out directly by the user.
Time and procedure for the prevention of the gearbox.
I recommend that you necessarily carry out the prophylaxis of a new gas trimmer immediately after purchase, with the addition of lubricant to the gearbox. Despite the high cost of gardening equipment, some manufacturers save and put grease only at a minimum, at the time of break-in.
How often to lubricate the lawn mowing gear.
Often, a routine inspection of the transmission with the addition of liquid grease is carried out once a year at the beginning or end of the season. If the gas trimmer is not used by you in professional volumes, this is enough.
For large mowing volumes, it is necessary to lubricate the lawn mowing gearbox every 20-50 hours of operation. If the operating conditions of the garden equipment are difficult, for example, a large field is mowed at a time, and the lawn mower does not have time to cool down, or cheap lubricants are used, then the grease must be checked and added every 20 hours of operation.
Indirect evidence that it is necessary to lubricate the gearbox may be overheating or increased unit noise. In these cases, if during inspection it is found that there is enough lubricant in the assembly by volume, then I recommend that it be replaced as a whole, while it is advisable to choose a different manufacturer of auto chemical goods. Also, a complete replacement of the lubricant, with disassembly and washing of the unit, I recommend when buying a used gasoline trimmer.

Assortment of lubricants for garden equipment
According to the instructions, a special transmission fluid grease should be used to lubricate the bevel gear. As a rule, gardening equipment manufacturers produce and recommend the chemistry of their brand as the most adapted to their devices.
At the same time, in order to reduce the cost of operating garden equipment and increase the attractiveness of the auto chemical brand, grease for garden equipment is usually produced multifunctional. It is intended not only for the lubrication of gearboxes of gasoline trimmers, but also for the processing of hoses, gears and gearboxes of any garden equipment and mechanical devices operating under high loads.
Even if the specialized lubricant for the gearbox was almost completely developed during operation, the additives still create an effective lubricating protective film on the surface of the gears.
It should be noted that many owners of lawn mowers in the former CIS expanses use conventional Litol-24 or lithium-based grease for lubricating the gearbox. It is convenient to refuel the gearbox with a 5-cc medical syringe. Many motorists, instead of the side screw, pick up the threads and screw the grease fitting from the cars that have served their crosspieces. This refinement allows the addition of Litol without disassembling the assembly using a grease gun.
An undoubted advantage of using Litol and lithium-based grease for refueling lawn mowing gears is the reduction in cost of operation. But there are nuances due to which spears break on forums of gardeners of Internet space. My thoughts on what can be lubricated with lithium-based lubricants and what is not, read the article “ Litol as a grease for lawn mowing gear ".

17 side bolt on gas trimmer gearbox
For safety reasons, in order to avoid accidental start-up, all preventive work on the lawn mower must be carried out with the electric cap / plug removed from the candle. Do not turn the trimmer over to avoid gas leaking.
We unscrew the side screw on the lawn mowing gear. Depending on the manufacturer of the garden tool, a turn-key bolt may be used instead of a hexagon screw, usually by 17. The thread is normal, turn off counterclockwise. Do not lose the sealing washer.
Add specialized grease
If no grease is visible on the inside of the screw, add 3-4 grams. Turn the gear by hand, changing the direction of rotation so that the grease is distributed over the gears. Repeat the operation several times. On average, about 5 to 10 g is included in the gearbox. The assembly must be completely filled with grease, taking into account the installation of the screw. Then reinstall the screw by tightening it firmly.
As you can see, it will not take a lot of time or special skills to lubricate the gearbox on the lawn mower. Usually, we’re going to take longer than we do the entire amount of preventive work. Reliable to you garden equipment. Share your experience with petrol trimmers in the comments.
