If you do not change filters...
When the filter is clogged – impurities, dust and dirt can enter into the interiors of the machine and damage the internal components which can affect machine performance and can also lead to machine breakdown.
If you do not change oils...
Shortage or contamination of oil can lead to deterioration in power, fuel economy and increased friction and wear of parts. Not only the performance of the engine is affected, but it can also lead to breakdown.
If you do not change tilling blade...
As the cultivation function decreases, good soil tillage cannot be done. Soil can accumulate around the tilling blades and rotate, which can result in increased burden on the tractor, which can deteriorate the fuel consumption.
