The 2920 MAX SEALER PLUS™ disc sealer has been designed for the operators who demand durability, longevity and performance in the field. The 2920 MAX SEALER PLUS™ has adjustable blade pitch to match the changes in soil tilth. The unit is heavy enough to fill the knife track and flexible enough to not cut a trench for water to start erosion. The 2920 MAX SEALER PLUS™ has independent arms to allow the blades to follow the roughest terrain and maintain soil flow to cover the knife track. Because each blade is independent the sealer can handle field conditions that have large amounts of crop residue, which keeps the toolbar productive even in less than ideal conditions.


The 2920 MAX SEALER PLUS™ is available in two models with three-blade style to choose from.
