Varibox HD

The varibox is a self-contained gearing system that allows an Agrowdrill operator to have greater control over the flow of seed through the main seed box of the seed drill. 

This varibox is used on most Agrowdrills, with the exception of smaller drills such as the AD083 and the small seeds box assembly. It has an input shaft on one side measuring 20mm. Two output shafts measuring 25mm and two control shafts measuring 16mm are on other side.

Variboxes use diesel oil with a grade of 15W-40.
