Assembly Supplement: Working Angle of 2-Bar Drag Harrow As an added feature, the straight and offset joiner links of the 2 bar drag sections have one end with two different angle cuts. This gives you the opportunity to set the spikes bars to run at a shallow angle of about 30°...
Assembly Supplement: Rollers When assembling the 300 DDSS Harrows it is important to note that there are left and right hand roll- ers. These are identified by a decal on the roller assemblies. If the decal is missing the rollers can be identified by looking at them from the end.

Start assembling the rollers with the front, middle roller in the center section and work out in both directions to the wings. Shift the center roller to the right so that it is 4" right of center and tighten to roller frame.
Assembly Completion: When the assembly of the harrows has been completed check to make sure that the complete assem- bly appears evenly spaced and centred across the back of the cultivator. If the harrow assembly is not centered you will have to shift the harrow sections as required. Improper centering of the rollers may cause the cultivator to pull crooked in the field.
Field Adjustments and Settings: The pull chains for the drag harrows may be shortened in order to raise the front bar and there- fore increase the working angle of the spikes. This will make the harrow more aggressive but may reduce the ability of the harrow to clear residue in some conditions.

NOTE: There are many factors that can affect the ability of the harrows to level or even out the soil surface behind the cultivator; Cultivator tine spacing, type of shares (sweeps), cultivating depth, ground speed, direction of travel across the field (angle), soil type, and soil conditions like moisture content and crop residue levels, all have an affect on the quality and levelness of the seed bed.
Maintenance: Periodically check all nuts and bolts and secure if loose. Lubricate the roller bearings after every 12 hours of operation. DO NOT OVER GREASE THE ROLLER BEARING: Over greasing may cause damage to the bearing seals. Periodically check and remove any foreign material that may become tangled in the harrow sections or wound around the rollers or bearings.
