4.6.Gear shift of The Tractor
The transmission usually requires no adjustment in its service life, however it is required to pay attention to
following items during service and maintenance:
The lubricating oil in the transmission can flow into the rear axle. The oil filler port is located on the rear axle
housing, and during oil drainage, the oil drain bolt on the rear axle housing should be unscrewed, and the scrap iron
adhered to the oil drainage bolt should be cleaned. Use an oil dipstick to inspect the lubricating oil level.
Correctly selecting a tractor operating speed is not only able to obtain optimal productivity and economy, but also
extend its service life. When the tractor is working, it should not be overloaded frequently, it is better make the
engine has certain power margin. The working speed during operation of the tractor in field should be selected in
such a manner that the engine is operated at about 80% load.
Where the tractor works at light load and low speed, the next higher gear and small throttle can be selected to save
fuel.
