INTRODUCTION

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.

are staying tight.

4. The chart below is a guide for proper torque. Use it unless a specified torque is called out

elsewhere in the manual.

5. Torque is the force you apply to the wrench handle or the cheater bar, times the length of the

handle or bar.

6. Use a torque wrench whenever possible.

The following table shows torque in ft. lbs.

Lubricate all bearings and moving parts as assembled and make certain that they work freely.

attention should be paid to lifting techniques while handling and or maneuvering the
units during assembly. Failure to do so may lead to personal injury. Use heavy gloves

while handling the blades during assembly and any time adjustments or maintenance
operations are made to the units.
