Changing The Transmission Fluid On A Kubota Tractor

Just as it is imperative that you maintain the family car so that it runs well, the same is the case for your Kubota tractor. One of the most important maintenance chores as far as the tractor is concerned is regularly changing the transmission fluid.

Changing the transmission fluid of a Kubota tractor is an essential part of good maintenance.

Keeping a Kubota tractor well maintained including changing the transmission fluid regularly is paramount for optimum performance.

If you are a skilled farmer, then you probably also have the skills to replace  the transmission fluid. To make the task a bit easier here are step-by-step instructions.

Take Precautions

Any time you are involved in maintaining a motor vehicle you should be cautious. It is advised that you wear protective gloves and glasses when performing the task.

It should also be understood that the transmission on a Kubota tractor includes two draining plugs –- one on the right side of the tractor and one on the left. To ensure that the transmission is fully drained, you must unplug the drained plug on both sides of the tractor.
