Assembling the Agri-Fab 45-02993 48-inch Plug Aerator involves several steps. Here's a detailed guide based on the product's instruction manual: First, assemble the aerator knives by attaching eight knives to the outside of each double spool assembly. Rotate each knife to lock the tab into the spool plate and secure them using a 5/16" x 3/4" carriage bolt and a 5/16" nylock nut. Next, prepare the spool assemblies and bearings by inserting the split plastic bearings into both ends of all spool assemblies. Then, attach the wheel brackets to the shaft's middle hole using a 1/4" x 1-3/4" hex bolt and a 1/4" nylock nut. Following this, assemble the spool assemblies and spacers onto the shaft, referring to the provided instructions for correct placement. Attach the wheels to the wheel brackets, using the specified bolts, washers, and nuts, ensuring the wheels spin freely but are securely fastened. Assemble the hitch bracket to the tongue using the appropriate bolts and nuts, securing the hitch pin through the bracket and tongue. Assemble the end plates to the tray's corners, but do not tighten the bolts and nuts at this stage. Now, attach the lift handle by inserting it through the slot in the tray and fastening it to the wheel bracket with bolts and nuts. Secure the lift handle further using a 3/8" x 1-1/4" hex bolt, a shoulder spacer, and a 3/8" nylock nut, tightening both nylock nuts firmly. Finally, attach the grip onto the lift handle to ensure a secure locking mechanism. Always consult the Agri-Fab 45-02993 48-inch Plug Aerator manual for detailed illustrations and any specific clarifications during assembly.
