How to service the Agrowdrill gearbox

Agrowdrill Variable Gearbox Maintenance.

Replacing the oil in your varibox is recommended to ensure correct function and longevity. The varibox gearboxes used in Agrowdrill models help ensure your seed drill's drive assembly continues to function smoothly over the life of the drill. 

Agrowdrill seeders have two different gearbox models. The recommended oil for both these models is the same. 

What grade of oil to use:

You should use a diesel engine oil grade 15W-40. Note that using a different oil grade may void the warranty on your gearbox. 

How much oil to use:

Most variboxes use between 3-4L of oil. They come with a level plug to provide a quick visual confirmation of the correct oil level. 

How often to check the oil level:

The oil level should be checked annually before sowing. 

How often to change the oil:

You should perform a complete oil change every three years.
