Common fault repair of tiller

author: Manhope
The micro-tiller is powered by a small diesel engine or gasoline engine, and has the characteristics of light weight, small size and simple structure. Micro-tillers are widely used in dry land, paddy fields, orchards, etc. in plains, mountainous areas, and hills. With the corresponding equipment, it can be used for pumping, power generation, spraying and other operations, and can also be towed by trailers for short-distance transportation.
The micro-tiller can be used freely in the field, which is convenient for users to use and store. It saves the trouble that large agricultural machinery cannot enter the mountainous fields. It is the best choice for farmers and consumers to replace cattle farming.

The micro-tiller has become the new favorite of farmers because of its lightness, flexibility, multi-function and low price. However, micro-tiller operators generally report that the failure rate of micro-tillers is high. Through years of promotion and investigation, we found that the reason for the high failure rate of micro-tillers is mostly caused by improper use and maintenance of the operator, and there are some misunderstandings in the use and maintenance. Now I will share some views on the investigation situation for the reference of the majority of micro-tiller operators.

When using the small cultibator, when a fault occurs, it is necessary to turn off the engine and stop for inspection. The following are common faults and repair methods:

1. The clutch cannot be disengaged.
If the clutch handle fails, the clutch handle should be repaired or replaced; if the clutch cable fails, the clutch cable should be replaced; if the bolt at the end of the positioning pin is loose, the cable should be adjusted and then tightened; if the friction plate fails, it should be replaced; if the release bearing is damaged, it should be replaced; The spring fails and should be replaced.
2. Clutch slips.
The separation fork is not fully combined, and the joint surfaces should be separated or cleaned several times; the clutch rocker arm is blocked from returning, and the obstacle to returning is cleared; the adjustment of the clutch cable is too short, resulting in the friction plate not being combined in place, and the cable needs to be readjusted , so that the friction plates are fully combined.​
3. The gear is not in place.
If the shift dial is too worn or loose, it should be replaced; if the inner shaft spring of the gearbox fails, the spring should be replaced; if the gearbox bearing is damaged or the nut is loose, causing the gearbox shaft to move axially, the bearing should be replaced or the nut should be tightened.​​
4. The V-belt slips.
If the V-belt is too loose or the belt is worn, the tightness of the V-belt should be replaced or adjusted.​​
5. There is a noise in the gearbox of the mini tiller.

Due to the harsh working environment of the tiller, maintenance is particularly important. In order to prevent the occurrence of the above situation, it is necessary to strictly implement the maintenance system of "prevention is more important than cure, and maintenance is more important than repair".
