Transmission (drive) mechanism

If you have a lawn mower with a drive (self-propelled), then for a long period of operation you will need to monitor the condition of the transmission (drive) mechanism. Depending on the manufacturer of the lawnmower, the drive system is different. But in general, there is quite a lot similar in the moments of maintenance.

First of all, pay attention to the condition of the drive shaft. As a rule, it can be wrapped around various objects (threads, ropes, fishing line, wire .....), about finding all these items on the lawn, you may not even suspect the threads and fishing line, can simply blow out the wind, and in the grass, Such items are difficult to notice. Especially it is necessary to be careful when mowing outside the site. Here everything is simple, when cleaning lawn mowers, after cutting, pay attention to the shaft, if you notice something like that, then remove foreign objects from the shaft. When operating a lawnmower with the objects wound on the drive shaft, you may encounter quite a costly repair. First of all, the packing glands of the reducer fail (the box that transfers the rotation from the drive belt to the shaft). The gear is filled with oil, and when oil seals fail, oil flows out, which leads to breakage. On some lawn mowers the manufacturer provides for the replacement of oil seals, but basically the gearbox is supplied entirely and its cost is 20-50% of the cost of the lawn mower. Therefore, we recommend to monitor the condition of the drive.

Another point when the drive of your lawnmower can fail. At a low position for a hairstyle, you can punch the reducer casing against a curb or tile, or when cornering, you can simply "comb" part of the reducer against the ground. Which also leads to loss of oil and failure of the drive mechanism. Again, when cleaning the lawn mower, pay attention to the reducer, if you saw chips and dents, then you should change the cutting system and be more careful.

Just pay attention to the ratchet mechanism in the gears of the drive located in the driving wheels. To control this unit you will need to remove the wheels. Often this site fails because of lack of lubrication and corrosion. But in the case of servicing the mechanism of gears, it is advisable to consult specialists. At each manufacturer and even in different models of lawnmowers of one manufacturer, the mechanism for transferring the torque from shaft to gear is quite different and consists of spring-loaded small parts that you can simply lose if you disassemble it yourself.
